Texture & feel
SENSORYDual-Action Acne Treatment
Combines a retinoid (Adapalene) with an antibacterial (Benzoyl Peroxide) for comprehensive multi-target acne control in a single application.
Kills Acne-Causing Bacteria
Benzoyl Peroxide 2.5% eliminates Cutibacterium acnes without developing bacterial resistance, even with long-term use.
Unclogs Pores & Prevents Comedones
Adapalene normalizes skin cell turnover, reducing microcomedone formation and preventing new blackheads and whiteheads from developing.
Reduces Inflammation
Adapalene inhibits inflammatory mediators and arachidonic acid metabolism, actively calming red, swollen papules and pustules.
Safety & compatibility
SAFEContains Adapalene (a retinoid). Retinoids are contraindicated during pregnancy due to potential risks to the unborn baby. Discontinue use if you become pregnant.
Limited data available. Systemic absorption is minimal, but consult your doctor before using while breastfeeding.

Oil-free gel formulation specifically designed for acne-prone skin. Very low risk of clogging pores.
Both adapalene and benzoyl peroxide increase photosensitivity. Daily SPF 30+ sunscreen is mandatory. Apply only in the evening.
Benzoyl peroxide permanently bleaches colored towels, bed linens, and hair. Use white pillowcases and wash hands thoroughly after application.
Effezel Gel is a prescription medication. Consult a dermatologist for proper diagnosis and treatment plan before use.
Free from fragrances, parabens, sulfates, silicones, harsh alcohols, oils, and common allergens.
Ingredient breakdown
INGREDIENTSAdapalene 0.1%Proven
A third-generation synthetic retinoid derived from naphthoic acid. Binds to specific nuclear retinoic acid receptors to normalize follicular cell differentiation, reducing microcomedone formation and providing potent anti-inflammatory action.
- Mechanism: Modulates cell differentiation and keratinization in hair follicles, preventing pore blockage at the source
- Anti-inflammatory: Inhibits AP-1 factors, toll-like receptor-2 expression, and arachidonic acid metabolism
- Clinical data: Recommended as first-line therapy by the Global Acne Alliance and American Academy of Dermatology
- Stability: More chemically stable than tretinoin, less irritating while maintaining comparable efficacy
Benzoyl Peroxide 2.5%Proven
A powerful oxidizing agent that kills Cutibacterium acnes bacteria on contact. Also provides keratolytic and sebiostatic effects, helping unclog pores and reduce excess sebum production.
- Antibacterial: Generates reactive oxygen species that destroy C. acnes without developing bacterial resistance
- Efficacy: Clinically proven to be equally effective at 2.5%, 5%, and 10% concentrations — lower concentrations cause less irritation
- Keratolytic: Softens and peels the outer skin layer, promoting cell turnover and clearing blocked pores
- Metabolism: Quickly converted to benzoic acid in the skin and rapidly excreted, with minimal systemic absorption
Glycerin SupportingProven
A powerful humectant naturally found in the skin. Helps counterbalance the drying effects of the active ingredients by drawing moisture into the skin and strengthening the moisture barrier.
- Humectant: Found to be more effective than AHAs and hyaluronic acid at attracting and retaining moisture in a 2016 study
- Barrier support: Helps maintain skin hydration and reduces the dryness caused by adapalene and benzoyl peroxide
Propylene Glycol SupportingFunctional
A solvent and humectant that helps deliver active ingredients deeper into the skin while also providing light moisturizing benefits.
- Penetration enhancer: Improves the delivery of adapalene and benzoyl peroxide into the skin
- Humectant: Draws water to the skin surface, helping maintain hydration

Where it fits in your routine
ROUTINEApply only in the evening (PM routine). Use a gentle, non-foaming cleanser. Always follow with a non-comedogenic moisturizer. SPF 30+ is mandatory during the day.
How to use
HOW TO USECleanse Your Skin
Wash your face with a gentle, soap-free cleanser (such as Cetaphil or CeraVe). Pat completely dry with a clean towel. Wait 1–2 minutes to ensure skin is fully dry.
Apply a Thin Layer
Use a pea-sized amount for each area of the face. Apply with fingertips to all acne-affected areas — not just individual spots. Avoid the eyes, lips, nostrils, and mucous membranes.
Wash Your Hands
Thoroughly wash hands after application to avoid transferring benzoyl peroxide to fabrics, hair, or other surfaces where it may cause bleaching.
Follow with Moisturizer
Wait 5–10 minutes for the gel to absorb, then apply a non-comedogenic moisturizer to combat dryness. During the first weeks, start every other night to build tolerance.
Who is it for?
WHOPerfect for you if:
- You have moderate to severe acne vulgaris with papules and pustules
- You struggle with persistent blackheads and whiteheads (comedones)
- You want a clinically proven prescription-strength treatment
- You need long-term acne management (can be used continuously)
- You are aged 9 years or older with oily or combination skin
- Over-the-counter treatments have not worked for you
Consider alternatives if:
- You are pregnant, planning pregnancy, or breastfeeding
- You have fungal acne (pityrosporum folliculitis)
- You have very sensitive, eczema-prone, or damaged skin
- You cannot commit to daily SPF use
- You need to preserve colored fabrics and cannot manage the bleaching
- You have an allergy to adapalene, benzoyl peroxide, or propylene glycol
Skin type compatibility
SKIN TYPESIdeal match. Benzoyl peroxide has sebiostatic effects that help reduce excess oil production. Oil-free gel formula absorbs without adding shine.
Works well on T-zone oiliness and breakout-prone areas. Apply only to affected zones to avoid over-drying cheeks or dry patches.
Specifically designed for acne-prone skin. Addresses all four acne pathways: excess sebum, bacteria, clogged pores, and inflammation.
Both active ingredients are drying. Pair with a rich non-comedogenic moisturizer and start every other night. May still cause excessive flaking.
High irritation potential. Burning, redness, and peeling are common, especially in the first weeks. Consider Differin alone as a gentler option.
Results timeline
MONTH 3–6Adjustment & Possible Purging

DUPES
Identical formulation to Effezel (Adapalene 0.1% + BPO 2.5%) marketed under a different brand name. Available in more markets. Same manufacturer (Galderma).
Contains only Adapalene 0.1% without Benzoyl Peroxide. Available OTC in most countries. Gentler but less effective on inflammatory acne — best for mild comedonal acne. Can be combined with a separate BPO product.
Contains only Benzoyl Peroxide 2.5% without the retinoid component. Good for targeting bacteria and excess oil but lacks the pore-unclogging and anti-aging benefits of adapalene. Available OTC.

Frequently asked questions
FAQNo. Effezel contains Adapalene, a retinoid, which is contraindicated during pregnancy due to potential risks to the developing baby. If you become pregnant while using Effezel, discontinue use immediately and consult your doctor. For breastfeeding, data is limited — systemic absorption is low, but it is recommended to consult your physician before use. Safe acne alternatives during pregnancy include azelaic acid and certain antibiotics prescribed by your doctor.
No. Effezel contains Sorbitan Oleate and Polysorbate 80, which are known to feed Malassezia yeast — the fungus responsible for fungal acne (pityrosporum folliculitis). Additionally, Isohexadecane is a potential fungal acne trigger. If you have fungal acne, consider alternatives like azelaic acid, sulfur-based treatments, or zinc pyrithione products instead.
It is not recommended to use Effezel with other retinoids (retinol, tretinoin), additional benzoyl peroxide products, or strong chemical exfoliants (AHA/BHA/glycolic acid) as this can cause severe irritation, dryness, and damage to the skin barrier. Vitamin C serums can be used in the morning (Effezel is PM only), but introduce slowly. Avoid any products with peeling, drying, or abrasive effects while your skin is adjusting to Effezel.
Effezel works best for oily, combination, and acne-prone skin types. It is specifically designed for moderate to severe acne vulgaris with comedones (blackheads/whiteheads), papules, and pustules. It is suitable for teenagers aged 9+ and adults. It is less ideal for dry or sensitive skin due to its drying and irritating properties — those skin types should start very slowly and use a rich moisturizer.
First signs of improvement typically appear after 1–4 weeks, though a temporary worsening (purging) is common in weeks 1–3. Significant visible improvement usually occurs at the 2–3 month mark. For optimal results, consistent use for 3–6 months is recommended. Many users report their skin clearing dramatically around the 3-month point. Do not give up during the initial purging phase — this indicates the treatment is working.
Apply Effezel once daily in the evening after cleansing and drying your skin. The order is: gentle cleanser, pat dry, Effezel Gel (thin layer), wait 5–10 minutes, then non-comedogenic moisturizer. In the morning, use a gentle cleanser, antioxidant serum (optional), moisturizer, and SPF 30+. Do not apply Effezel in the morning as both ingredients increase sun sensitivity.
Effezel has a very low comedogenic rating of 1 out of 5. It is an oil-free gel formulation specifically designed for acne-prone skin and is unlikely to clog pores. In fact, its active ingredient Adapalene works by unclogging pores and preventing microcomedone formation. The formula is free from oils, silicones, and other known pore-clogging ingredients.
Effezel Gel has a Period After Opening (PAO) of 6 months. Once opened, use within 6 months for optimal efficacy. Unopened, it has a shelf life of 2 years when stored at room temperature (20°–25°C / 68°–77°F). Keep the tube capped and stored away from direct heat and light to maintain stability of the active ingredients.
Verdict: Effezel Gel is a highly effective, clinically proven prescription acne treatment that combines two gold-standard active ingredients — Adapalene and Benzoyl Peroxide — in a single, clean formula with just 12 ingredients. It earns its reputation as a first-line therapy for moderate to severe acne, supported by global dermatology guidelines and extensive clinical evidence. The initial adjustment period (dryness, purging, irritation) is demanding, but users who persist through the first 2–3 months consistently report dramatic skin improvement. Its limitations — not safe for pregnancy, not fungal acne safe, fabric bleaching, and mandatory SPF use — are important to consider. For oily and acne-prone skin types willing to commit to the process, Effezel delivers exceptional long-term results that justify the prescription.

Understanding Simple Alcohols
Alcohol ingredients are widely used in cosmetics and come in different types. For the most part alcohols are not problematic at all. However one type of alcohols, simple alcohols can be quite drying to the skin because it evaporates very quickly. This can cause irritation which can also lead to other skin complications. These alcohols should never be used alone on your skin, but combined with other cosmetic ingredients, they are normally without issue. However, for some people with sensitive and easily irritable skin, avoiding products with these simple alcohols may be beneficial.

Silicone-Free
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.
Note, that this does not include all ingredients part of the Silicone class of ingredients.
EU Allergen-Free
EU Allergen-Free
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.
For more information regarding the EU's Scientific Committee on Consumer Safety, please visit their official website.
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. 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.
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.
