Welcome to the PPX Discovery Club

First and foremost—thank you.

Thank you for believing in ProPigmentRx, for trusting my formulations, and for being willing to continue investing in your education. The PPX Discovery Club was created for estheticians who don’t just want to use products—they want to understand why they work.

Every month, you’ll receive exclusive formulations developed inside the ProPigmentRx lab before they become available anywhere else. This is your opportunity to experience new ingredients, evaluate formulations, learn how different actives work together, and build confidence in choosing the right ingredients for your clients.

Why We Started with PDRN & Ectoin

For our very first Discovery Club release, I wanted to focus on two ingredients that are transforming corrective skincare but are still misunderstood by many professionals: PDRN and Ectoin.

Although these ingredients perform differently, they share one important goal—creating healthier, more resilient skin.

PDRN

PDRN is all about regeneration and repair. It supports the skin’s natural recovery process, making it an excellent ingredient for compromised, dehydrated, aging, or post-procedure skin. Think of PDRN as an ingredient that helps the skin recover more efficiently while supporting overall skin quality.

PDRN pairs exceptionally well with:

• Growth factors (EGF)
• Hyaluronic Acid
• Panthenol
• Ceramides
• Copper Peptides
• Beta-Glucan
• Barrier-supporting ingredients

Ectoin

Ectoin is one of my favorite barrier-support ingredients because it helps protect skin from environmental stress while strengthening moisture retention. It’s an incredible ingredient for reactive, inflamed, dehydrated, compromised, and higher Fitzpatrick skin, making it one of the most versatile ingredients available today.

Ectoin pairs beautifully with:

• Niacinamide
• Ceramides
• Panthenol
• Colloidal Oatmeal
• Beta-Glucan
• Hyaluronic Acid
• Tranexamic Acid
• N-Acetyl Glucosamine

When Should You Reach for These Ingredients?

Both ingredients can be used year-round, but they truly shine when the skin is under stress.

Whether your client has recently undergone chemical peels, microneedling, laser treatments, or simply has a compromised skin barrier from over-exfoliation or environmental exposure, PDRN and Ectoin work together to help support recovery while improving hydration, resilience, and overall skin function.

As estheticians, we often focus on correcting pigmentation, acne, and aging—but none of those concerns can be treated effectively without first respecting the skin barrier. Healthy skin responds better to treatment, heals more efficiently, and delivers more predictable results.

That’s exactly why these two ingredients were chosen to launch the PPX Discovery Club.

Your Assignment This Month

Don’t just use these products—study them.

Try them on different skin types. Use them before and after procedures. Layer them with different actives. Pay attention to texture, hydration, recovery, barrier function, and overall skin response.

The goal of the Discovery Club isn’t simply to receive products. It’s to become a more knowledgeable esthetician with every monthly shipment.

Welcome to the very first month of the PPX Discovery Club.

I’m excited to learn, formulate, and grow alongside you.

AUGUST DISCOVERY CLUB EDUCATION

RETINOL vs. BAKUCHIOL

Same goal. Different chemistry. Different way of getting there.

This month’s Discovery Club is all about retinol and bakuchiol—two ingredients that get compared constantly in skincare, and honestly… often misunderstood.

You’ve probably heard bakuchiol called:
“natural retinol,” “plant-based retinol,” or “nature’s retinol.”

And while that sounds clean and simple for marketing, it’s not scientifically accurate.

Let’s be clear:

Bakuchiol is NOT retinol.
It is NOT a retinoid.
It does NOT convert into retinoic acid in the skin.

What is true is that bakuchiol can create similar-looking results in the skin through completely different biological pathways. That’s where the confusion started and why this comparison matters.

We chose these two actives for a reason.

Not to decide which one is “better,” but to help you understand:

• what each ingredient actually is
• how they work differently
• where they overlap
• and why formulation + skin type matters more than marketing claims

PART ONE: RETINOL

WHAT IS RETINOL?

Retinol is a vitamin A derivative and part of the retinoid family.

That matters because all retinoids are connected to retinoic acid, the active form of vitamin A that drives most of the changes we associate with retinol use.

Retinol itself is not the final active form. It has to convert in the skin:

RETINOL → RETINALDEHYDE → RETINOIC ACID

Once it becomes retinoic acid, it binds to specific receptors in the skin and influences how skin cells behave at a genetic level.

This is why retinol is so powerful and why it’s so well studied.

HOW RETINOL WORKS

Retinol is not just “an exfoliant.”

It works much deeper than that.

It influences:

SKIN CELL BEHAVIOR
Helps regulate how skin cells grow, mature, and turn over.

COLLAGEN SUPPORT
Supports collagen production while helping reduce breakdown pathways that accelerate aging.

SKIN RENEWAL
Improves overall texture and smoothness over time through consistent cell turnover.

PHOTOAGING
One of the most researched ingredients for sun-related aging changes in the skin.

PIGMENT APPEARANCE
Helps improve uneven tone by supporting healthier skin turnover and function.

So instead of targeting one issue, retinol works more like a global skin regulator.

It’s working at a cellular communication level—not just the surface.

WHY RETINOL CAN BE IRRITATING

Here’s the trade-off.

Because retinol is biologically active, the skin can sometimes react while adjusting.

Common responses include:

• dryness
• redness
• flaking
• tightness
• sensitivity
• barrier disruption

This is especially important when working with pigment-prone skin.

Because here’s the truth:

Too much inflammation can actually make pigmentation worse.

So the goal is never:

“How strong can we go?”

The real question is:

“What level of retinol gives results without stressing the skin barrier?”

PART TWO: BAKUCHIOL

WHAT IS BAKUCHIOL?

Bakuchiol is a plant-derived compound found in certain botanical sources.

Chemically, it is completely different from retinol.

And this is important:

Bakuchiol is NOT vitamin A
It is NOT a retinoid
It does NOT convert into retinoic acid
It does NOT behave like retinol in the same pathway

So when people call it “natural retinol,” that’s marketing—not science.

A more accurate way to describe it is:

a retinol-like functional active

Because it can create some similar visible outcomes without using the same biological system.

HOW BAKUCHIOL WORKS

Research became more interesting when scientists compared how bakuchiol and retinol affect skin at a gene-expression level.

Even though they are structurally different, they showed overlapping activity in pathways related to skin aging and collagen support.

That’s where the “retinol-like” conversation comes from.

But notice the wording:

retinol-like FUNCTION

Not:

retinol chemistry

That difference is everything.

Bakuchiol has been shown to influence:

COLLAGEN SUPPORT
Helps support markers related to skin structure and firmness.

SKIN TEXTURE
Improves the look of fine lines and uneven texture over time.

PIGMENT APPEARANCE
Has shown improvement in uneven tone in clinical research.

OXIDATIVE + INFLAMMATORY STRESS
Has antioxidant and calming properties that may support overall skin resilience.

But important note:

The research on bakuchiol is still growing.
It does not have the same decades of data as retinol.

THE STUDY THAT CHANGED THE CONVERSATION

One well-known clinical study compared:

• 0.5% bakuchiol (twice daily)
• 0.5% retinol (once daily)

After 12 weeks, both groups saw improvements in:

• wrinkles
• texture
• pigmentation

But the retinol group reported more irritation—like dryness and stinging.

The conclusion?

Bakuchiol performed similarly in that study for those specific outcomes, with better tolerability.

But here’s the key point:

That does NOT mean they are the same ingredient.

It means:

two different ingredients can produce overlapping results in certain conditions.

Not identical mechanisms. Not identical biology.

WHY BAKUCHIOL IS CALLED “NATURAL RETINOL”

This is where marketing steps in.

Because “bakuchiol is a plant-derived compound with retinol-like gene expression activity” is not exactly consumer-friendly language.

So it gets simplified into:

“natural alternative to retinol” → “natural retinol”

And over time, that gets misunderstood as:

they are the same thing

They are not.

This is a perfect example of how marketing can take real science and simplify it so much that the meaning gets lost.

RETINOL vs. BAKUCHIOL (REAL DIFFERENCE)

RETINOL

• Vitamin A derivative
• Works through conversion to retinoic acid
• Strong, well-researched, predictable
• Can be irritating if misused
• Decades of clinical data

BAKUCHIOL

• Plant-derived compound
• Not a retinoid
• Does not convert to vitamin A pathways
• May influence similar visible outcomes
• Generally better tolerated
• Still emerging research

SAME RESULT ≠ SAME PATHWAY

This is the biggest takeaway.

Both ingredients can influence:

• collagen
• texture
• pigmentation
• skin aging
• overall skin quality

But they do NOT do it the same way.

In skincare, we have to stop assuming:

same result = same mechanism

Because biology doesn’t work like that.

There are always multiple ways to reach similar skin outcomes.

WHY THIS DROP MATTERS

This month isn’t about choosing a “winner.”

It’s about learning how to think like a skin professional.

We want you to:

• use both
• observe both
• compare both
• understand both

Because real education comes from understanding why something works not just what it’s called.

When you understand the mechanism, you stop relying on marketing to make decisions for you.

WHAT TO PAY ATTENTION TO

As you use these actives, notice:

TOLERANCE
Which one causes more dryness or sensitivity?

TEXTURE
How does the skin feel over time?

PIGMENT
How does tone change with consistent use?

BARRIER HEALTH
Does the skin stay balanced or feel stressed?

CONSISTENCY
Which one is easier for your client to actually stick with?

Because the best ingredient in the world means nothing if the skin can’t tolerate it consistently.

FINAL TAKEAWAY

Don’t let marketing define ingredients for you.

Don’t assume “natural” means better, gentler, or weaker.

And don’t assume two ingredients are the same just because they look similar on the surface.

Bakuchiol doesn’t need to be retinol to be effective.
Retinol doesn’t need a replacement to still be gold-standard.

Both have a place.

Both work differently.

And understanding that difference is what makes you better at what you do.

AFTERCARE

WHAT CAN YOUR CLIENT EXPECT? 

the skin may temporarily feel and appear similar to a mild to moderate sunburn.

Depending on the client’s skin, number of layers and treatment intensity, normal post-treatment responses may include:

• Flaking
• Scaling
• Mild scabbing
• Redness
• Dryness
• Mild swelling

These responses can vary significantly from client to client. Visible peeling is not required for the treatment to be effective.

POST-TREATMENT CARE

Keep the skin hydrated, protected and undisturbed while it recovers.

Do not pick, peel, scratch or manually remove flaking skin. Avoid scrubs, exfoliating acids, retinoids and other potentially irritating actives until the skin has recovered.

Avoid additional exfoliating or aggressive professional treatments during the recovery period.

Use a gentle cleanser, appropriate moisturizer and broad-spectrum SPF daily. Minimize unnecessary sun and heat exposure while the skin is recovering.

If the skin develops a reaction that is excessive, prolonged or inconsistent with the expected post-peel response, discontinue potentially irritating products and evaluate the skin before resuming the normal regimen.

Why I Chose Succinic Acid and Salicylic Acid

One of the biggest mistakes I see in acne care is treating every breakout as though it is the same. It isn’t.

Two people can both say, “I have acne,” while presenting with completely different skin conditions. One may have blackheads and closed comedones caused by compacted oil and dead skin inside the follicle. Another may have red, inflamed blemishes where microbial activity and inflammation play a larger role. Many people experience a combination of both—sometimes alongside sensitivity, barrier damage, and post-inflammatory hyperpigmentation.

Yet the common response is often the same: exfoliate harder, dry the skin out, or reach for the strongest acid available. That approach can leave the skin more irritated without addressing what is actually driving the breakout.

That is why I chose succinic acid and salicylic acid as September’s Actives of the Month. They allow us to examine two different places where a cosmetic active may intervene in the acne pathway.

Where Salicylic Acid Fits

Salicylic acid is most useful when follicular congestion is a major part of the problem.

Because it is oil-affinitive, salicylic acid can work effectively within the oil-rich environment of the follicle. Its primary action is desmolytic and comedolytic: it loosens the adhesion between accumulated surface cells so compacted keratin and sebum can shed more normally.

In practical terms, salicylic acid helps address the physical blockage that contributes to:

• Blackheads
• Closed comedones
• Rough, congested texture
• Oil-heavy breakout patterns
• The early microcomedones from which visible acne lesions can develop

Salicylic acid’s place in acne care is not simply to “dry out a pimple.” Its more meaningful role is helping prevent and release the follicular plug.

However, more salicylic acid is not automatically better. Excessive strength or frequency can create dryness, irritation, and barrier disruption. In skin that is already inflamed or prone to post-inflammatory hyperpigmentation, that additional irritation may create another problem while attempting to correct the first one.

Where Succinic Acid Fits

Succinic acid occupies a different position.

It is a water-soluble dicarboxylic acid, but it should not be viewed as another exfoliating acid or as a direct substitute for salicylic acid. Succinic acid does not have the same established comedolytic action.

Interest in succinic acid comes largely from emerging microbiome research. Succinic acid is one of the substances that can be produced through microbial fermentation. Preclinical research has shown that it can inhibit the growth of Cutibacterium acnes—formerly called Propionibacterium acnes—and reduce C. acnes-induced inflammation in experimental models.

Its proposed antimicrobial action involves creating conditions that interfere with bacterial growth, including disruption of the organism’s internal pH and metabolic environment.

This gives succinic acid an interesting potential place in formulas designed for inflamed, blemish-prone skin, particularly when the goal is to support a healthier microbial and inflammatory environment without depending entirely on aggressive exfoliation.

However, it is important to keep the science in perspective. The evidence for succinic acid in finished topical products and human acne is still developing. It is best described as an emerging, supportive cosmetic active, not as a proven replacement for established acne medications.

Why Compare Them?

This comparison is not about deciding which acid “wins.” It is about understanding that they address different parts of the breakout process.

Salicylic acid primarily addresses the plug. It is the more established choice when retained cells, oil, blackheads, and closed comedones are central to the condition.

Succinic acid explores the environment surrounding the blemish. Its potential value lies in supporting formulas concerned with microbial activity and inflammation, without approaching every breakout as a problem that must be exfoliated away.

Some clients may benefit from one approach. Others may need a carefully designed formula or treatment strategy that addresses both congestion and inflammation. The correct choice depends on the lesion type, the condition of the barrier, the degree of inflammation, and the overall acne pattern.

That is the real lesson behind this month’s Discovery Club comparison:

The best active is not necessarily the strongest one. It is the active whose mechanism matches what is happening in the skin.

Acne education begins when we stop asking, “What is the best ingredient for acne?” and start asking, “What type of acne am I looking at, and which part of its biology am I trying to address?”

Glycolic Acid vs. Encapsulated Glycolic Acid

Why 5% Does Not Tell the Whole Story

When an esthetician sees 5% glycolic acid on a product, that percentage only identifies how much glycolic acid was added to the formula. It does not fully explain how quickly the acid becomes available, how strongly it interacts with the skin, how it will feel during application, or how well a client will tolerate repeated use.

To understand an acid product, estheticians must look beyond the featured active. The product’s pH, free-acid level, delivery system, base, texture, supporting ingredients, application method, contact time, and frequency of use all influence its behavior.

Two products can each contain 5% glycolic acid and create noticeably different skin experiences.

Understanding Standard Glycolic Acid

What Is Glycolic Acid?

Glycolic acid is a water-soluble alpha hydroxy acid, commonly called an AHA. It has the smallest molecular structure among the commonly used AHAs, which allows it to move through the water-rich pathways of the stratum corneum relatively efficiently.

Its primary cosmetic action occurs within the outermost layers of the epidermis. Glycolic acid changes the environment surrounding compacted corneocytes and influences the structures that help hold those cells together. This encourages a more organized shedding process and reduces the buildup of dull, uneven surface cells.

Rather than thinking of glycolic acid as simply “removing dead skin,” estheticians should understand it as an ingredient that helps normalize surface renewal.

What Does Glycolic Acid Do?

1. Improves rough and uneven texture

When corneocytes accumulate unevenly, the skin can appear dull, rough or lackluster. Glycolic acid encourages those compacted cells to release more evenly, helping the skin appear smoother and more reflective.

That increased reflection of light is one reason glycolic acid is often associated with “glow.” The glow is not glitter, oil or an artificial shine. It comes from creating a smoother surface that reflects light more evenly.

2. Supports the correction of superficial discoloration

Glycolic acid is not primarily a tyrosinase inhibitor, and it does not directly shut down every stage of melanin production. Its role in a pigment regimen is different.

As epidermal cells move toward the surface, they carry melanin with them. By encouraging more consistent shedding of pigmented surface cells, glycolic acid can help improve the appearance of superficial postinflammatory discoloration and uneven tone.

This makes glycolic acid especially useful when paired with ingredients that address other stages of pigment formation. The acid manages surface accumulation while pigment-regulating ingredients address melanocyte signaling, tyrosinase activity, melanin transfer or inflammation.

Clinical studies have found that glycolic acid can contribute to improvements in postinflammatory hyperpigmentation in darker skin types when it is selected carefully and used under appropriate supervision. Irritation must still be controlled because excessive inflammation can stimulate additional pigment production. 

3. Helps manage visible congestion

Glycolic acid can be helpful for skin with surface congestion, compacted corneocytes and noninflamed comedonal activity. By reducing the buildup of cells around the follicular opening, it helps prevent surface debris from becoming as tightly compacted.

Glycolic acid is water soluble, so it does not behave exactly like oil-soluble salicylic acid. It is generally more focused on epidermal renewal and surface cohesion, while salicylic acid has a stronger relationship with oily follicular environments.

A clinical study evaluating a 5% glycolic acid product reported improvements in mild to moderate acne-related lesions and overall skin appearance, although product selection should still be based on the type of congestion and the amount of inflammation present. 

4. Improves the appearance of photodamage

With consistent and controlled use, glycolic acid can improve the appearance of fine lines, roughness, uneven tone and other visible signs of photodamage.

Its immediate activity is concentrated in the stratum corneum, but repeated use can also signal changes in epidermal renewal and dermal matrix activity. Research on glycolic acid formulations has documented improvements in photoaged skin, including with daily 5% formulations. 

These effects are gradual. A home-care glycolic product should not be presented as producing the same response as a professional chemical peel simply because both contain glycolic acid.

Where Is Standard Glycolic Acid Appropriate?

Standard free glycolic acid may be appropriate when the esthetic goal is to address:

• Dull, rough or uneven texture
• Compacted surface buildup
• Superficial postinflammatory discoloration
• Uneven tone and loss of luminosity
• Mild, noninflamed congestion
• Fine lines and visible photodamage
• Skin that has become accustomed to regular AHA use
• Thicker or more resilient skin that requires direct exfoliating activity

Glycolic acid can be used across Fitzpatrick skin types, but the treatment decision should never be based on Fitzpatrick type alone. The esthetician must also evaluate the client’s barrier, inflammatory history, current home care, previous reactions and tendency to develop postinflammatory hyperpigmentation.

When to delay or reduce glycolic acid use

Use should be delayed or modified when the skin presents with:

• Active barrier impairment
• Persistent burning, tightness or flaking
• Active dermatitis or eczema
• Open lesions or excoriated acne
• Sunburn
• Recent waxing or aggressive exfoliation
• Recent laser, resurfacing or other procedures that temporarily weaken the barrier
• Uncontrolled inflammation
• A routine already overloaded with acids, retinoids, benzoyl peroxide or abrasive exfoliants

In pigment-prone skin, irritation is not a harmless temporary reaction. Irritation can initiate an inflammatory response that contributes to additional melanocyte stimulation. The objective is controlled exfoliation without creating unnecessary inflammation.

Why the pH Matters

The percentage tells us the total glycolic acid content. The pH helps tell us how much of that glycolic acid is immediately available in its more active, unneutralized form.

At a lower pH, a larger proportion of the glycolic acid remains in the free-acid form. Free acid generally penetrates and acts more readily, but it also has a greater potential to create stinging, erythema and irritation.

As the formula is adjusted to a higher pH, more of the glycolic acid converts into its glycolate form. The total glycolic content may still be 5%, but its immediate activity and skin feel can change.

Human skin absorption research has demonstrated that glycolic acid penetration is influenced by pH, concentration and contact time. The same concentration penetrated differently when tested at different pH levels. 

This means:

A lower-pH 5% glycolic product may behave more aggressively than another 5% glycolic product formulated at a higher pH.

The presence of sodium hydroxide in an ingredient list usually indicates that the formulator adjusted the finished pH. However, the ingredient list does not tell an esthetician the final pH or exact free-acid value. Those values must be obtained from finished-product testing.

Understanding Encapsulated Glycolic Acid

What Does “Encapsulated” Mean?

Encapsulated glycolic acid is still glycolic acid. Encapsulation changes the way the acid is carried and released within the formula.

In a liposomal delivery system, glycolic acid is associated with tiny phospholipid structures called liposomes. Phospholipids have both water-compatible and lipid-compatible portions, allowing them to organize into microscopic vesicles.

Phosphatidylcholine, the phospholipid used in the PPX Encapsulated Glycolic Acid Toner, helps form this delivery structure.

Instead of all of the available glycolic acid making immediate contact with the skin at once, the liposomal system is designed to modulate its release and distribution.

A useful way to explain it is to compare pouring water onto the ground with using drip irrigation. Both methods may deliver the same total amount of water, but they do not deliver it at the same speed or create the same immediate impact.

What Role Does Encapsulation Play?

1. Modulates the initial release

With standard free glycolic acid, the available acid begins interacting with the skin as soon as the formula is applied.

With an encapsulated system, a portion of the acid is held within or associated with the delivery structure. The carrier can release that acid more gradually instead of presenting the skin with the entire available amount at one time.

Laboratory research has demonstrated that liposomal systems can alter glycolic acid release. 

2. May reduce the immediate sensory impact

The sudden availability of free acid contributes to the sharp sting, heat or immediate redness some clients associate with glycolic acid.

A more controlled release may reduce that initial peak of acid exposure. This can create a more measured skin experience and may improve tolerance in clients who find conventional glycolic products uncomfortable.

A clinical evaluation of a liposomal glycolic acid gel reported improvements in photodamage with fewer glycolic acid-related side effects than the comparison glycolic gel. Those findings apply to the specific delivery system tested and should not be assumed for every encapsulated product. 

3. Creates a different activity curve

Standard glycolic acid may create a more immediate rise in activity. Encapsulation can flatten that curve by spreading availability across a longer period.

This does not necessarily mean that encapsulated glycolic acid is weak. It means the skin may receive the acid differently.

A client may experience less immediate stinging while the product continues to provide meaningful exfoliating activity. Less sensation does not automatically mean less performance.

4. Can improve distribution across the skin

A well-designed carrier system can help distribute glycolic acid more evenly throughout the applied area. More even distribution may reduce concentrated areas of activity caused by uneven application or rapid absorption.

However, encapsulation does not guarantee perfect delivery. Performance depends on the type of carrier, encapsulation efficiency, particle size, phospholipid composition, stability, finished pH and release behavior of the final product.

The word “encapsulated” alone does not tell the entire story, just as the percentage alone does not tell the entire story.

Where Is Encapsulated Glycolic Acid Appropriate?

Encapsulated glycolic acid may be especially useful for:

• Clients beginning an AHA routine
• Clients who experience immediate stinging from traditional glycolic products
• Pigment-prone clients who require a more controlled approach to exfoliation
• Clients needing ongoing surface renewal between professional treatments
• Skin with dullness, rough texture or superficial uneven tone
• Clients who need regular exfoliation but do not tolerate a strong initial acid sensation
• Estheticians who want to introduce glycolic activity gradually while monitoring the skin’s response

Encapsulation does not make glycolic acid universally appropriate for sensitive or compromised skin. If the barrier is actively impaired, even a controlled delivery system may be poorly tolerated.

The esthetician must still evaluate the client’s barrier, current regimen, treatment history and inflammatory response.

Understanding the Sensory System in the 5% Glycolic Acid Serum

The PPX Glycolic Acid Serum contains standard glycolic acid in a base supported by:

• Snail secretion filtrate
• Glycerin
• Panthenol
• Hydrolyzed silk
• Hydroxyethylcellulose

These ingredients change the way the formula spreads, sits on the skin and feels after application.

Glycerin binds water and helps reduce the dry, tight after-feel sometimes associated with acid products.

Panthenol supports hydration and barrier comfort.

Snail secretion filtrate contributes humectant and film-forming components that give the serum a more conditioned skin feel.

Hydrolyzed silk forms a light film and contributes slip and softness.

Hydroxyethylcellulose creates the serum’s gel structure, improving application control, cushion and residence on the skin.

These ingredients can make a free glycolic acid formula feel more hydrated, silky and comfortable. They do not automatically neutralize the glycolic acid or convert it into an encapsulated acid.

In strict formulation language, these are better described as sensory and tolerance modifiers. A true chemical buffer controls or resists changes in pH. In this formula, sodium hydroxide is the ingredient used to adjust the pH and influence the balance between free glycolic acid and glycolate.

This distinction is essential:

A formula can feel cushioned and comfortable while still delivering active glycolic acid.

Stinging should never be used as the sole measurement of product strength or performance.

Reading the Complete Formula

When evaluating an acid product, estheticians should ask:

1. What percentage of acid is present?
   This tells you the total amount, but it is only the starting point.
2. What is the finished pH?
   The pH helps determine how much glycolic acid is immediately available in its free-acid form.
3. Is the acid free, partially neutralized or encapsulated?
   The delivery form affects how quickly the skin is exposed to the acid.
4. What is the product base?
   A toner, watery essence, gel serum and cream can distribute and remain on the skin differently.
5. What supports the sensory experience?
   Humectants, film formers and rheology modifiers can change slip, hydration, spread and after-feel.
6. What else is in the formula?
   Alcohol, botanical waters, penetration enhancers, soothing ingredients and other actives can all influence tolerance.
7. How is the product being used?
   Frequency, amount, contact time and the rest of the client’s regimen can make the same product appropriate for one client and excessive for another.
8. What condition is the skin in today?
   The percentage printed on the label cannot assess inflammation, barrier integrity or a client’s pigment response. That is the esthetician’s responsibility.

The PPX Discovery Club Takeaway

Both products contain 5% glycolic acid, but the number does not tell the complete formulation story.

The 5% Glycolic Acid Serum delivers standard glycolic acid through a hydrating, film-forming serum base. Snail secretion filtrate, glycerin, panthenol, hydrolyzed silk and the gel network change the spread, glide, hydration and overall sensory experience of the acid.

The 5% Encapsulated Glycolic Acid Toner uses a phospholipid delivery system designed to modulate how the glycolic acid becomes available to the skin.

One formula cushions the experience through its serum base and supporting ingredients. The other changes the acid’s delivery profile through encapsulation.

That is why estheticians must stop judging acid products by percentage alone. The complete formula determines how the acid is delivered, how the skin experiences it, and whether it is appropriate for the client in front of you
