Ingredient breakdown
INGREDIENTSBenzoyl Peroxide 5%Gold Standard
The most effective over-the-counter acne treatment available. BPO works through multiple mechanisms: antibacterial action against C. acnes, keratolytic exfoliation, and sebum reduction.
- Mechanism: Releases free radicals that destroy bacterial cell walls and reduce inflammation
- Efficacy: Eliminates 94% of acne-causing bacteria within hours of application
- Research: Studies show 2.5-5% concentrations are as effective as 10% with less irritation
- Safety: Metabolized to benzoic acid and rapidly excreted via urine
Glycerol (Glycerin) HumectantProven
A powerful humectant naturally found in skin. Helps counteract the drying effects of benzoyl peroxide by attracting and retaining moisture.

- Research: 2016 study found glycerin more effective than AHAs and hyaluronic acid as a humectant
- Safety: Comedogenic rating of 0, hypoallergenic
Carbomer 940 ThickenerVehicle
A high-molecular weight polymer that creates the gel-like suspension consistency. Allows even distribution of BPO across skin.
- Function: Thickening agent and formula stabilizer
- Penetration: Large molecular size means minimal skin absorption
- Safety: Considered an inert, non-irritating ingredient at typical concentrations
Sodium C14-16 Olefin Sulfonate CleanserSurfactant
A mild surfactant that provides cleansing action without harsh sulfates like SLS. Creates the foaming/lathering effect.
- Function: Removes oil, dirt, and debris from skin surface

Frequently asked questions
FAQPregnancy: Benzoyl peroxide is FDA Category C. While only about 5% is absorbed through skin and rapidly metabolized to benzoic acid, there are no controlled studies in pregnant women. Consult your doctor before use during pregnancy.Breastfeeding: According to LactMed, topical BPO is considered low risk for nursing infants due to minimal absorption. However, avoid applying to breast area and ensure baby's skin doesn't contact treated areas.
Yes, Benzaknen Wash 5% is safe for fungal acne. Research published in PMC shows that benzoyl peroxide has microbicidal activity against Malassezia species (the yeast causing fungal acne). The formula also contains no oils, fatty acids, or other ingredients known to feed Malassezia. While BPO isn't a dedicated antifungal, it won't worsen fungal acne and may help through its keratolytic (exfoliating) action.
Retinol: Use with caution. Both can be drying. Apply BPO wash in AM and retinol at PM to minimize irritation.Vitamin C: Generally safe but may reduce efficacy of both. Use vitamin C in AM routine, BPO at different times.AHA/BHA: Can increase irritation significantly. Start by alternating days, not using together. If using BHA (salicylic acid) leave-on products, skip the BPO wash that day until skin adjusts. Always introduce new combinations gradually.
Benzaknen Wash 5% is ideal foroily, combination, and acne-prone skin. The 5% concentration offers a good balance of efficacy and tolerability. It's particularly effective for body acne on chest, back, and shoulders. Those with dry or very sensitive skin should use with caution, starting with less frequent application and always following with moisturizer. Not recommended for those with eczema or severely compromised skin barrier.
Most users seevisible improvement within 1-2 weeks of consistent use. Clinical studies show "clinically visible improvement" by week 3, withmaximum lesion reduction at 8-12 weeks. Initial dryness or mild peeling in the first few days is normal and usually subsides. If no improvement after 4-6 weeks, consult a dermatologist about alternative treatments.
Benzaknen Wash 5% should be yourfirst cleansing step. Apply to wet skin, massage for 1-2 minutes to allow the BPO to work, then rinse thoroughly. Follow with toner (optional), any leave-on treatments, moisturizer, and sunscreen (AM). Can be used once or twice daily depending on skin tolerance. For sensitive skin, start with once daily (PM recommended) and increase frequency as tolerated.
No, Benzaknen Wash 5% isnon-comedogenic with a rating of 0/5. It will not clog pores. In fact, benzoyl peroxide actively helps unclog pores through its keratolytic action, breaking down the "horn plugs" that trap sebum and bacteria. The formula contains no oils or pore-clogging ingredients. It's dermatologically tested and specifically designed for acne-prone skin.
Benzaknen Wash 5% has aPAO (Period After Opening) of 12 months. Store at room temperature (20-25°C/68-77°F) away from heat and direct sunlight. Shake well before each use. If the product changes color, smell, or texture before the 12-month mark, discontinue use. Check the expiry date printed on the tube before opening.
Verdict: Benzaknen Wash 5% is a highly effective, German pharmacy-grade benzoyl peroxide wash that delivers what it promises. With its minimal 8-ingredient formula, clinical backing, and proven 94% bacteria-killing efficacy, it's an excellent choice for those dealing with mild to moderate acne - especially body acne. The 5% concentration hits the sweet spot between effectiveness and tolerability. While the drying effect and fabric-bleaching properties are drawbacks, the results speak for themselves with visible improvement in just 1-2 weeks. Best suited for oily and combination skin types who want a no-nonsense, science-backed approach to acne treatment.

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.

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.

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.
