โ Frequently Asked Questions
Benzoyl peroxide is FDA Category C for pregnancyโno adequate human studies exist, but due to minimal systemic absorption (only ~5% is absorbed), it's generally considered low risk. The AAD and NIH consider low-concentration BP (2.5%) safe for use during pregnancy, especially in the second and third trimesters. For breastfeeding, it's considered low risk, but avoid applying to areas that may contact baby during feeding. Always consult your healthcare provider before use.
Yes, this product is fungal acne safe. The formula contains no fatty acids, ferments, oils, esters, or polysorbates that feed Malassezia yeast. Additionally, clinical research shows that benzoyl peroxide has microbicidal activity against Malassezia species (M. furfur, M. restricta, M. globosa), making it potentially helpful for fungal acne. The gel destroys yeast cell walls similarly to how it kills C. acnes bacteria.
Yes, but with caution. BP can be combined with retinoids (tretinoin, adapalene)โin fact, this is a dermatologist-recommended combination. However, using them at the same time may increase irritation. Best practice: use BP in the morning and retinoid at night, OR apply retinoid first, wait 10-15 minutes, then apply BP. For vitamin C: they can be used in the same routine but at different times. For AHA/BHA: avoid layering directly together to prevent over-exfoliationโalternate days or use at different times of day.
This product is best for oily, combination, and acne-prone skin types. It works excellently for inflammatory acne (red, swollen pimples) and can help with fungal acne. The 2.5% concentration is the gentlest BP option, making it suitable for those new to benzoyl peroxide or with mild sensitivity. Those with very dry or eczema-prone skin should use with extra moisturization or consider a wash-off BP product instead.
According to clinical studies and manufacturer guidance: clinically visible improvements typically begin by week 3 of consistent use. Maximum lesion reduction is expected around 8-12 weeks. Some users may experience initial "purging" (temporary increase in breakouts) during weeks 1-2 as clogged pores come to the surface. Continuing use is required to maintain clear skinโstopping treatment often leads to acne returning.
Apply after cleansing and toning, before serums and moisturizer. The order is: 1) Cleanser, 2) Toner (optional), 3) Benzoyl Peroxide Gel, 4) Wait 1-2 minutes, 5) Serum (optional), 6) Moisturizer, 7) Sunscreen (morning only). For sensitive skin, you can try the "sandwich method"โapply moisturizer first, then BP, then another layer of moisturizer to buffer irritation.
No, this product has a comedogenic rating of 0/5โit will not clog pores. The aqueous (water-based) gel formula is oil-free and non-comedogenic. In fact, benzoyl peroxide actively helps unclog pores through its mild keratolytic (exfoliating) action, removing dead skin cells and excess sebum that contribute to acne formation.
The product has a Period After Opening (PAO) of 12 months when stored properly at room temperature (15-30ยฐC / 59-86ยฐF). Always check the expiration date printed on the tube. Store away from heat and direct sunlight to maintain potency. If the product changes color, smell, or texture, discard it even if within the PAO period. Recent benzene contamination concerns suggest storing BP products in cool, dry places and discarding if exposed to high heat.
Verdict: Perrigo Benzoyl Peroxide 2.5% Gel is a highly effective, dermatologist-recommended acne treatment that delivers prescription-grade results at a drugstore price. The 2.5% concentration is backed by clinical studies showing equal efficacy to higher strengths (5-10%) with significantly less irritationโmaking it ideal for beginners and those with sensitive skin. The fragrance-free, fungal acne-safe formula tackles inflammatory acne without promoting antibiotic resistance. While the potential for bleaching fabrics and initial dryness are drawbacks, the affordable price point, proven efficacy, and minimal ingredient list make this a standout choice for anyone dealing with mild to moderate acne.

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
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 ยซpromisesยป 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.

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.
