Texture & feel
SENSORYOmniSome Delivery System
Patented technology that stabilizes and carries 2x more salicylic acid deeper into the skin compared to standard formulas for superior blemish-clearing results.
Dual Acid Action
Combines BHA (salicylic acid) with AHA (mandelic acid) to exfoliate both inside pores and on the skin surface, tackling acne from multiple angles.
Anti-Discoloration Complex
Hexylresorcinol and ethyl linoleate work together to fade post-acne dark spots and promote an even skin tone while treating blemishes.
Fast-Acting Formula
Clinically shown to visibly improve the appearance of breakouts in as early as three days with consistent use.
Safety & compatibility
SAFEContains 2% salicylic acid, an FDA Pregnancy Category C ingredient. Topical salicylic acid at 2% is generally considered low-risk in small areas, but consult your OB/GYN before use. Avoid full-face application during pregnancy.
Not fungal acne safe. Contains Polyglyceryl-10 Dioleate (an oleic acid ester) and Ethyl Linoleate (a fatty acid ester), both of which can feed malassezia yeast.
Oil-free gel formula with a comedogenic rating of 1/5. Unlikely to clog pores, and the BHA active actually helps unclog them.
SD Alcohol 40-B is listed as the second ingredient. Can be drying for some users. If dryness occurs, reduce to spot-treatment use only and follow with a moisturizer.
PCA SKIN states this product is helpful for calming breakouts associated with rosacea without causing sensitivity.
BHA and AHA exfoliants can increase sun sensitivity. Always apply a broad-spectrum SPF 30+ during the daytime when using this product.
Ingredient breakdown
INGREDIENTSSalicylic Acid 2%Proven
The gold-standard BHA (beta hydroxy acid) for acne treatment. Oil-soluble, allowing it to penetrate deep into pores to dissolve sebum buildup, dead skin cells, and bacteria. Delivered via PCA SKIN's patented OmniSome system for enhanced penetration.
- Mechanism: Exfoliates inside pores (comedolytic), reduces inflammation, and has mild antibacterial properties.
- FDA Status: 2% is the maximum OTC concentration approved for acne treatment.
- OmniSome Advantage: In vitro data shows 2x more salicylic acid reaches the skin vs. standard delivery.
Mandelic Acid UndisclosedProven
A gentle alpha hydroxy acid (AHA) derived from bitter almonds. Has a larger molecular size than glycolic acid, making it less irritating while still effectively exfoliating the skin surface and reducing oil production.
- Benefit: Exfoliates surface dead skin cells, unclogs pores, and helps regulate sebum production.
- Research: Studies show mandelic acid is effective for acne treatment, especially for darker skin tones due to lower irritation potential.
- Synergy: Works alongside salicylic acid to provide both surface and within-pore exfoliation.
Hexylresorcinol UndisclosedProven
A potent skin-brightening agent originally used in the food industry as an anti-browning compound. Now a well-researched cosmetic ingredient with significant tyrosinase-inhibiting ability to fade post-acne marks.
- Efficacy: Clinical studies show 0.5% hexylresorcinol has comparable brightening effects to 2% hydroquinone.
- Mechanism: Inhibits tyrosinase, the enzyme needed to produce melanin, helping to fade post-inflammatory hyperpigmentation.
Ethyl Linoleate UndisclosedPromising
An ester of linoleic acid (omega-6 fatty acid) that helps promote an even skin tone and reduce unwanted discoloration. Works synergistically with hexylresorcinol for brightening benefits.
- Benefit: Supports skin barrier function while helping to brighten and even out skin tone.
- Note: Acne-prone skin often has lower linoleic acid levels in sebum, so topical application may help normalize composition.

How to use
HOW TO USECleanse & Tone
Start with a gentle cleanser, then apply your toner. Pat skin dry before proceeding.
Apply Acne Gel
Dispense a small amount and apply as a spot treatment on active blemishes, or apply a thin layer over the entire face if your skin is oily or acne-prone.
Allow to Absorb
Let the gel absorb fully into the skin for about 30 seconds before layering other products on top.
Moisturize & Protect
Follow with a lightweight, non-comedogenic moisturizer. In the daytime, always finish with a broad-spectrum SPF product. If dryness occurs, reduce to spot-treatment use only.
Who is it for?
WHOPerfect for you if:
- You have oily or combination skin with frequent breakouts
- You want a professional-grade salicylic acid treatment
- You deal with blackheads, whiteheads, or cystic acne
- You want to address both acne and post-acne dark spots simultaneously
- You experience rosacea-related breakouts and need a gentle approach
- You prefer a lightweight, fragrance-free, fast-absorbing gel
Consider alternatives if:
- You have very dry or dehydrated skin (the alcohol content may be too drying)
- You are pregnant or breastfeeding (consult your doctor first)
- You have fungal acne / malassezia folliculitis (not FA-safe)
- You are on a tight budget ($72/oz is a premium price point)
- You are already using multiple strong exfoliants (risk of over-exfoliation)
- You have an allergy to aspirin or salicylates
Skin type compatibility
SKIN TYPESIdeal match. The lightweight gel and BHA/AHA combo regulate oil production, unclog pores, and leave a matte finish without greasiness.
Great for T-zone application. Can be used full-face or as a spot treatment on oily areas while skipping drier zones.
Specifically formulated for this skin type. Non-comedogenic, clears existing blemishes, and prevents new ones from forming.
The brand states it calms rosacea-related breakouts. However, the alcohol content and acids may cause initial stinging. Start with spot treatment and patch test first.
Use only as a spot treatment. The alcohol base and exfoliating acids can be quite drying. Must pair with a rich moisturizer and may cause peeling.
Works well for occasional breakouts and as preventive maintenance. Use as a spot treatment rather than full-face for the best balance.

Budget-friendly alternatives (dupes)
DUPES
Same 2% salicylic acid concentration at a fraction of the cost. Uses squalane as a carrier instead of alcohol, making it less drying. However, lacks the OmniSome delivery, mandelic acid, and brightening agents.
Contains 2% salicylic acid plus AHAs (glycolic and lactic acid), niacinamide, and ceramides. Better for dry/sensitive skin due to barrier-supportive ingredients. Lacks mandelic acid and the OmniSome delivery system.
A cult-favorite 2% BHA liquid with green tea extract. Larger 4 oz size offers better value. Liquid format (not gel) and no AHA or brightening ingredients. More hydrating and less drying than PCA SKIN.

Frequently asked questions
FAQUse with caution. PCA SKIN Acne Gel contains 2% salicylic acid, which is classified as FDA Pregnancy Category C. While topical application of 2% salicylic acid on small areas is generally considered low-risk, the American College of Obstetricians and Gynecologists recommends limiting use during pregnancy. Avoid full-face application and consult your OB/GYN or dermatologist before use during pregnancy or while breastfeeding.
No, the current reformulated PCA SKIN Acne Gel is not considered fungal acne safe. It contains Polyglyceryl-10 Dioleate (an oleic acid ester) and Ethyl Linoleate (a fatty acid ester), both of which can potentially feed malassezia yeast and worsen fungal acne. If you have pityrosporum folliculitis, consider alternatives like The Ordinary Salicylic Acid 2% Masque or a simple benzoyl peroxide treatment instead.
Since this gel already contains both BHA (salicylic acid) and AHA (mandelic acid), layering additional acid exfoliants on top is not recommended, as this can lead to over-exfoliation, irritation, and a damaged skin barrier. Retinol can be used in a separate routine (e.g., acne gel in the morning, retinol at night) but should be introduced gradually. Vitamin C serums (L-ascorbic acid) may be used, but apply at a different time of day to avoid pH conflicts and irritation.
PCA SKIN Acne Gel is best suited for oily, combination, and acne-prone skin types. It can also benefit those with rosacea-associated breakouts. People with dry or sensitive skin should use it only as a spot treatment rather than full-face, as the alcohol base and acid combination can be drying. The brand recommends it for oily, acneic, or combination skin for full-face use and as a spot treatment for occasional breakouts on all skin types.
PCA SKIN states the gel can visibly improve breakouts in as early as three days. Based on user reviews, most people notice active blemishes flattening within 1–3 days. Full clearing and improvement in overall skin tone typically takes 3–4 weeks of consistent use. Some users experience a brief purging period in weeks 1–2 where clogged pores come to the surface before clearing. For best long-term results, plan on at least 2–3 months of regular use.
Apply PCA SKIN Acne Gel as Step 3 in your routine: after cleansing and toning, but before serums, moisturizers, and sunscreen. The brand recommends applying it right after cleansing and toning, then following with the appropriate broad-spectrum SPF product in the daytime and a moisturizer in the evening. Allow the gel to absorb fully before layering other products.
No. PCA SKIN Acne Gel has a comedogenic rating of 1 out of 5, meaning it is very unlikely to clog pores. The formula is oil-free and uses a lightweight gel base. In fact, the active ingredient (salicylic acid) is specifically designed to unclog pores by dissolving the sebum and dead skin cell buildup inside them. The mandelic acid further supports pore clearing by exfoliating the skin surface.
PCA SKIN Acne Gel has a Period After Opening (PAO) of 12 months. Once opened, use within one year for optimal efficacy. The airless pump packaging helps preserve the active ingredients by minimizing air exposure and contamination. Store in a cool, dry place away from direct sunlight. If the product changes color, consistency, or smell before the 12-month mark, discontinue use.
Verdict: PCA SKIN Acne Gel is a professional-grade, fast-acting salicylic acid treatment that delivers on its promise of clearing blemishes quickly — often within days. The patented OmniSome delivery system and the addition of mandelic acid and hexylresorcinol set it apart from basic BHA treatments by addressing both active acne and post-acne discoloration in one step. It excels for oily and acne-prone skin types, and the fragrance-free, lightweight gel format is easy to work into any routine. However, the premium $72 price tag for just 1 oz, the drying alcohol base, and the fact that it is not fungal acne safe are notable drawbacks. Budget-conscious shoppers can find effective 2% BHA alternatives at a fraction of the cost, but if you want a multi-tasking professional treatment with enhanced delivery technology and brightening benefits, the PCA SKIN Acne Gel is a solid investment for persistent breakouts.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.

Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.

Disclaimer
The EU Allergen Free label is for the 26 ingredients identified by the EU SCCS and products will be only flagged if a suspected ingredient is on it's ingredient list. It is possible for cosmetics to contain one of the suspect ingredients without it appearing on the ingredient list due to it not reaching the concentration threshold to disclose it and cosmetic manufacturers choice to not disclose it.
Also note, the EU Allergen Free label is not personalized for your own allergies you may have and it does not constitute as medical advice.

Fungal Acne (Molassezia) Safe
Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
What are Notable Effects & Ingredients?
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Pro Tip Alert!
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

What is the Ingredient Safety Breakdown?
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
Pro Tip Alert!
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
