Sébionex Purifying Dermatological Bar
Sébionex Purifying Dermatological Bar
Product Description
By Laboratoire ACM — a soap-free, physiological-pH dermatological cleansing bar formulated for combination, oily and acne-prone skin. Its patented Sébo-Régul complex (zinc salts + piroctone olamine + lactic acid) lifts away excess sebum and impurities on both face and body, without the tight, stripped feeling of traditional soap. A 100g French-pharmacy staple that doubles as a daily face and body wash.
✨ Texture & Feel
Sébo-Régul Complex
Zinc sulfate, zinc PCA and piroctone olamine work together to help regulate excess oil and limit the bacteria linked to blemishes.
Soap-Free Cleansing
A syndet base cleanses at skin-friendly physiological pH, so there's no tight, stripped feeling after rinsing.
Clinically Tested
In a 28-day brand use-test on 20 people, 100% said it did not dry the skin and 90% found their skin clearer.
Face & Body
One bar tackles oil and breakouts on the face as well as the back, chest and shoulders.
🛡️ Safety & Compatibility
A rinse-off cleanser with no retinoids, hydroquinone or chemical sunscreens, and no salicylic acid in the actual INCI. The only AHA is a low level of lactic acid. Generally considered safe — confirm with your doctor.
Contains piroctone olamine, an antifungal that actively targets Malassezia, and it rinses off. Cetearyl alcohol and hydrogenated castor oil are technically flagged, but pose minimal risk in a wash-off product.
The formula includes Parfum (fragrance). If your skin is very reactive or you are sensitive to fragrance, patch test first or choose a fragrance-free alternative.
Pairs well before BHA, benzoyl peroxide or retinoid treatments. Avoid combining with harsh scrubs to prevent over-exfoliation and irritation.
🔬 Ingredient Breakdown
🫧 Sodium Lauryl Sulfate & Potassium Lauryl Sulfate Cleansing base Proven
Two sulfate surfactants form the cleansing engine of the bar, creating a creamy foam that binds and lifts away oil, dirt and impurities so they can be rinsed off.
- Function: Surfactants that produce foam and remove sebum and grime effectively.
- Note: Studies link prolonged or high-concentration SLS exposure to potential skin irritation.
🍋 Lactic Acid Low / pH-adjust level Proven
A gentle alpha-hydroxy acid (AHA) that loosens the "glue" between dead skin cells for smoother, more even-toned skin, while also acting as a humectant.
- Research: Larger molecules than glycolic acid mean it exfoliates more gently with less sting.
- Bonus: Studies show it can support ceramide production and the skin's moisturizing factor (NMF).
🍄 Piroctone Olamine Active Proven
A water-soluble antifungal best known from anti-dandruff shampoos, included here to help keep the skin's microbial balance in check.
- Action: Particularly effective against Malassezia, the yeast linked to dandruff and fungal acne.
- Role: Part of the Sébo-Régul complex helping limit bacterial and fungal proliferation.
⚗️ Zinc Sulfate Active Promising
A synthetically produced zinc salt with antimicrobial and astringent properties — despite the "sulfate" name, it is not a foaming surfactant.
- Function: Helps limit bacterial growth and tighten the look of skin.
- Pairing: Works alongside zinc PCA for the formula's oil-controlling effect.
🪙 Zinc PCA Active Promising
A zinc salt of pyrrolidone carboxylic acid valued for sebum regulation and soothing in oily, acne-prone skin.
- Benefits: May help reduce redness, regulate sebum and support skin's healing process.
- Best for: Especially useful for those with oily, congestion-prone skin.
💧 Glycerin Humectant Proven
A naturally skin-identical humectant that draws moisture into the skin, helping offset any tightness from the cleansing agents.
- Research: A 2016 study found glycerin more effective as a humectant than AHAs and hyaluronic acid.
- Barrier: Well-hydrated skin maintains a stronger barrier against irritants and bacteria.
🌽 Zea Mays (Corn) Starch Top 1 Proven
Cornstarch is the highest-listed ingredient, acting as an absorbent base that helps mop up excess oil and gives the bar its solid structure.
- Function: A natural absorbent that can replace talc; pH around 5.92.
- Texture: Helps thicken and bind the bar into a stable, mattifying format.
🧈 Cetearyl Alcohol Emollient Proven
A blend of fatty alcohols (cetyl + stearyl) used as an emollient and emulsifier to soften skin and stabilize the bar.
- Safety: Studies show it is non-toxic and non-irritating; the FDA allows "alcohol-free" labels with fatty alcohols.
- Source: Usually derived from plant oils such as coconut or palm.
🥥 Cocamidopropyl Betaine Co-surfactant Proven
A coconut-derived secondary surfactant that boosts gentle cleansing and creamy lather while softening the harshness of the primary sulfates.
- Function: Gathers dirt and impurities for rinse-off and thickens the foam.
- Research: A 2012 study found pure cocamidopropyl betaine is not the allergen it was once blamed for.
🍬 Sugar Humectants: Glucose, Rhamnose & Glucuronic Acid Humectants Promising
A trio of skin-identical sugars that hydrate and act as prebiotics, helping support a healthy skin microbiome.
- Glucose: A humectant that draws moisture and acts as a prebiotic; may help fade discoloration.
- Glucuronic Acid: A humectant and precursor of ascorbic acid found in fermentation products.

📝 How to Use
Wet
Dampen your face and/or body with lukewarm water.
Lather
Rub the bar between wet hands to build a creamy foam — apply the foam, rather than rubbing the bar directly on the skin.
Massage
Work the lather over skin in gentle circular motions, avoiding the eye area.
Rinse
Rinse thoroughly with clear, lukewarm water and pat dry. Use once or twice daily.

💰 Budget-Friendly Alternatives (Dupes)
A pH 5.5 soap-free syndet bar aimed at blemish-prone skin. Cleanses gently like Sébionex but lacks the zinc + piroctone olamine sebum-regulating complex.
A gentle syndet bar with ceramides and a similar soap-free feel, but with no oil-controlling actives — better suited to normal or dry skin than oily.

❓ Frequently Asked Questions
It is generally considered low-risk. It is a rinse-off cleanser with no retinoids, hydroquinone or chemical sunscreens, and despite some retailer descriptions, the actual INCI list contains no salicylic acid — the only AHA is a low level of lactic acid, which is widely regarded as safe in wash-off products. As always with pregnancy and breastfeeding, confirm with your doctor or midwife before use.
It leans fungal-acne friendly. The formula contains piroctone olamine, an antifungal that actively targets Malassezia, and it rinses off the skin. Two ingredients — cetearyl alcohol and hydrogenated castor oil — are technically flagged by ingredient databases as potentially not malassezia-safe, but in a brief-contact wash-off bar the risk is minimal. If you are highly reactive, patch test first.
Yes. As a gentle cleanser it works well as the first step before applying treatments like retinol, vitamin C, AHAs, BHAs or benzoyl peroxide. Because it already contains a mild AHA (lactic acid) and zinc, avoid stacking it with harsh physical scrubs in the same session to prevent over-exfoliation and irritation.
It is designed for combination, oily and acne-prone skin, where the zinc-based Sébo-Régul complex helps regulate sebum and limit breakout-linked bacteria. Dry skin may find it too clarifying, and very sensitive skin should patch test because of the sulfates and added fragrance.
Most people notice cleaner, fresher, less-tight skin from the first wash. In the brand's 28-day use-test, 85% reported reduced excess sebum and 90% found their skin clearer over four weeks. As a cleanser, it supports your routine rather than acting as a fast-acting spot treatment, so give it a few weeks of consistent daily use.
It is your very first step, morning and/or evening. Lather between wet hands, massage onto wet skin, then rinse. Follow with toner (optional), your active treatments, moisturizer, and sunscreen in the daytime. It can also be used on the body — back, chest and shoulders.
The brand labels it non-comedogenic, and we rate it about 1 out of 5. It is a rinse-off product, and even its richer ingredients like paraffinum liquidum are considered non-comedogenic, so it is very unlikely to clog pores for most people.
Plan to use it within about 12 months of opening. To make a 100g bar last and stay hygienic, keep it on a draining dish so it dries fully between uses and store it somewhere cool and dry, away from constant water and steam.
Verdict: The Sébionex Purifying Dermatological Bar from Laboratoire ACM is a smart, affordable French-pharmacy pick for oily, combination and acne-prone skin. Its soap-free, physiological-pH base cleanses without the tight feeling of traditional soap, while the zinc and piroctone olamine Sébo-Régul complex genuinely helps with oil control and clarity — backed by a small but positive clinical use-test. The trade-offs are added fragrance, sulfate surfactants and mineral oil, which make it less ideal for very sensitive or dry skin and for strict fragrance-avoiders. As a gentle, multi-tasking face-and-body cleanser to anchor an acne-fighting routine, it offers excellent value.

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.

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 are Ingredients Related to Skin Type?
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
Pro Tip Alert!
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!

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.
