Texture & feel
SENSORYKills Acne Bacteria on Contact
USP-grade micronized Benzoyl Peroxide 5% penetrates deep into pores to eliminate P. acnes bacteria and reduce inflammation within hours.
Exfoliates & Resurfaces
Glycolic Acid 5% gently dissolves dead skin cells, unclogs pores, increases cell turnover, and helps reduce acne scarring over time.
Soothes While Treating
Botanical extracts including Calendula, Echinacea, and Allantoin calm irritation and reduce redness so your skin stays comfortable.
Goes On Clear
Unlike white-cast BP products, this serum applies completely clear, making it suitable for use under makeup or on its own day or night.
Safety & compatibility
SAFEBenzoyl Peroxide is FDA Category C but ACOG considers topical BP generally acceptable during pregnancy due to minimal absorption (~5%). Glycolic Acid 5% is also considered low risk. Consult your OB-GYN before use. Avoid applying to breast area while nursing.
No ferments, fatty acids, esters, polysorbates, or oils. This formula is safe for fungal acne-prone skin. Benzoyl Peroxide may also help reduce Malassezia overgrowth.
Oil-free, silicone-free formula with a comedogenic rating of 1/5. Unlikely to clog pores or contribute to breakouts.
Both Benzoyl Peroxide and Glycolic Acid increase photosensitivity. Always use SPF 30+ sunscreen during the day when using this product.
Benzoyl Peroxide can bleach towels, pillowcases, and clothing. Use white linens or allow product to fully absorb before contact with fabrics.
Initial breakouts (purging) may occur in the first 2–4 weeks as the formula accelerates cell turnover. This is normal and typically subsides.
Ingredient breakdown
INGREDIENTSBenzoyl Peroxide (USP Grade, Micronized) 5%Gold Standard
The most well-researched topical acne ingredient available. USP-grade means it meets or exceeds purity standards set by the United States Pharmacopeia. Micronized particles allow deeper pore penetration with less surface irritation.
- Mechanism: Generates oxygen inside pores, killing anaerobic P. acnes bacteria on contact
- Efficacy: 2.5% and 5% concentrations shown equally effective; 5% offers faster initial results
- Unique: No bacterial resistance has ever been reported to Benzoyl Peroxide, unlike topical antibiotics
- Oil control: Brand claims up to 85% reduction in pore oil production
Glycolic Acid 5%Proven
The most researched Alpha Hydroxy Acid (AHA), derived from sugar cane. At 5%, it provides gentle yet effective chemical exfoliation to keep pores clear and boost cell renewal.
- Action: Dissolves the bonds between dead skin cells, promoting faster shedding and renewal
- Pore clearing: Removes cellular debris from inside pores, helping prevent comedones
- Bonus: Stimulates natural hyaluronic acid production, improving skin hydration over time
- Scarring: Regular use helps fade post-inflammatory hyperpigmentation and smooth acne scars
Calendula Officinalis Flower ExtractPromising
A soothing botanical with well-documented anti-inflammatory and antibacterial properties. Helps calm irritation caused by acne and the active ingredients in this formula.
- Properties: Anti-inflammatory, antimicrobial, and wound-healing support
- Benefit: Helps moisturize dry or chapped skin, counteracting the drying effects of BP
AllantoinProven
Derived from the comfrey plant, Allantoin is a well-known skin protectant that soothes, heals, and promotes healthy cell growth. Helps offset potential irritation from active ingredients.
- Soothing: Calms irritated and inflamed skin, reducing redness and discomfort
- Healing: Promotes healthy tissue formation and supports the skin's natural repair process
Echinacea Purpurea ExtractPromising
Coneflower extract with natural antiseptic and anti-inflammatory properties. Traditionally used to support the body's immune response, it helps reduce skin inflammation associated with acne.
- Anti-inflammatory: Helps reduce swelling and redness around active breakouts
- Antiseptic: Provides additional antimicrobial support alongside Benzoyl Peroxide
Gluconolactone (PHA)Proven
A polyhydroxy acid (PHA) that provides gentle exfoliation with additional antioxidant and moisturizing benefits. Larger molecular size makes it less irritating than AHAs alone.
- Gentle exfoliation: Complements glycolic acid without compounding irritation significantly
- Humectant: Attracts moisture to the skin, helping counterbalance the drying effects of BP

Where it fits in your routine
ROUTINEApply after cleansing and toning on clean, dry skin. Wait 1–2 minutes before layering moisturizer on top. Always follow with SPF in the morning.
How to use
HOW TO USECleanse Thoroughly
Wash your face with a gentle, pH-balanced cleanser and pat dry. Ensure skin is completely clean and dry before application.
Apply a Thin Layer
Dispense a pea-sized amount and spread a thin, even layer over the face and neck. Avoid the eye area, lips, and mouth. Can also be used as a spot treatment.
Let It Absorb
Allow the serum to fully absorb for 1–2 minutes before applying any additional products. The formula goes on clear with no white residue.
Follow with Moisturizer & SPF
Apply a hydrating moisturizer to offset potential dryness. In the morning, always finish with SPF 30+ sunscreen. Use once daily to start, building up to twice daily as tolerated.
Who is it for?
WHOPerfect for you if:
- You have mild to moderate inflammatory acne (pimples, whiteheads, blackheads)
- You deal with hormonal or cyclical breakouts
- You want a clear-drying formula that works under makeup
- You need a treatment for face AND body acne (back, chest)
- You have oily or combination skin prone to excess sebum
- You prefer fragrance-free, clean formulas
Consider alternatives if:
- You have very dry or sensitive skin that reacts easily to actives
- You are already using prescription retinoids (risk of over-exfoliation)
- You have a known allergy to Benzoyl Peroxide
- You want a purely hydrating serum with no active treatment ingredients
- You have severe cystic acne requiring prescription intervention
- You cannot commit to daily sunscreen use
Skin type compatibility
SKIN TYPESIdeal match. BP reduces sebum production up to 85%, and the oil-free gel formula won't add shine. Lightweight and matte-finishing.
Works well on oily T-zone breakouts. Apply to acne-prone areas only and follow with moisturizer on drier zones.
Effective for occasional breakouts. Pair with a good moisturizer since BP can be drying even on balanced skin.
Can be drying — use as a spot treatment rather than full-face. Always layer a rich moisturizer on top. Start with once every other day.
The dual-active formula (BP + AHA) may be too intense for very reactive skin. Patch test first and start with spot application only.
This product was specifically formulated for acne-prone skin. Non-comedogenic, oil-free, and fungal acne safe formula.

Budget-friendly alternatives (dupes)
DUPESLower BP concentration (2.5% vs 5%) and no glycolic acid. Larger size (2 oz) at half the price. Includes dimethicone for smoother finish but no botanical soothing extracts. Better for BP beginners.
Higher BP concentration (10% vs 5%) but no glycolic acid or soothing botanicals. Much more affordable but also more likely to cause dryness and irritation. Best for spot treatment only.
Wash-off cleanser format (not leave-on like DRMTLGY). Lower concentration and shorter contact time means less potent, but gentler option. No glycolic acid. Great as a complementary cleanser step.

Frequently asked questions
FAQUse with caution. Benzoyl Peroxide is FDA Category C, but the American College of Obstetricians and Gynecologists (ACOG) considers topical BP generally acceptable during pregnancy because only about 5% is absorbed systemically and it is rapidly metabolized into benzoic acid and excreted. Glycolic Acid at 5% is also considered low risk. However, there are no controlled human studies, so always consult your OB-GYN before starting any acne treatment during pregnancy. While breastfeeding, BP is considered low risk — just avoid applying to the breast area and ensure your baby's skin does not contact treated areas.
Yes. This formula contains no ferments, fatty acids (like oleic or lauric acid), fatty acid esters, polysorbates, or oils that feed Malassezia yeast. The ingredient list is remarkably clean with only 15 ingredients. Additionally, Benzoyl Peroxide may actually help control fungal overgrowth due to its broad antimicrobial properties, making this a solid choice for those dealing with both bacterial acne and fungal acne simultaneously.
Be careful with layering. This serum already contains Glycolic Acid (AHA) 5%, so adding additional AHA or BHA products on the same application can lead to over-exfoliation, irritation, and a damaged skin barrier. Retinol: Avoid using on the same night — alternate evenings (BP one night, retinol the next). Vitamin C: Use Vitamin C in the morning and this serum at night, as BP can oxidize and reduce Vitamin C efficacy. BHA (Salicylic Acid): Not recommended to layer on top — the combined drying effect can be harsh. Always introduce new combinations gradually.
This serum is best suited for oily, combination, and acne-prone skin types. People with oily skin benefit most since BP helps reduce sebum production (up to 85% according to the brand). It also works well for normal skin with occasional breakouts. Those with dry or sensitive skin can still use it but should apply it as a spot treatment rather than full-face and always follow with a rich moisturizer. The brand states it is safe for dry, oily, combination, and normal skin types.
Many users report visible reduction in active breakouts within the first 24 hours. Significant improvement in overall acne and skin clarity typically occurs within 4–6 weeks of consistent use. Some users experience an initial purging phase during weeks 1–3 where existing clogged pores come to the surface — this is temporary and a sign the product is working. For full results including scar fading and texture improvement, allow 8–12 weeks of regular use.
Apply as Step 3 in your routine: after cleansing and toning, but before moisturizer and sunscreen. Apply to clean, dry skin. Wait 1–2 minutes for full absorption before layering your moisturizer on top. In the AM, always finish with SPF 30+. For nighttime use, apply after cleansing and follow with a hydrating night cream. The brand recommends starting once daily (preferably PM) and increasing to twice daily as tolerated.
No. This serum has a comedogenic rating of 1 out of 5, making it very unlikely to clog pores. The formula is completely oil-free and silicone-free with only 15 ingredients. It contains no known pore-clogging ingredients. In fact, both active ingredients (Benzoyl Peroxide and Glycolic Acid) actively work to unclog pores and dissolve the buildup that causes comedones (blackheads and whiteheads).
The serum has a Period After Opening (PAO) of 12 months. Despite the small 1.1 oz bottle, most users report it lasting 2–3 months with daily use since only a pea-sized amount is needed per application. Store in a cool, dry place away from direct sunlight and heat. Proper storage is especially important for Benzoyl Peroxide products — avoid storing above 77°F (25°C) to maintain product stability and safety.
Verdict: DRMTLGY 24 Hour Acne Serum is a potent, no-nonsense acne treatment that delivers on its promise of fast results. The combination of USP-grade Benzoyl Peroxide 5% and Glycolic Acid 5% makes it more powerful than most OTC alternatives that rely on BP alone. The inclusion of six soothing botanical extracts helps offset irritation, and the clean, fragrance-free formula is a welcome bonus. The main trade-offs are the small bottle size relative to the price and the potential for dryness — but for oily and acne-prone skin types seeking a clear-drying, medical-grade treatment backed by 2,000+ dermatologists, this is one of the most effective options available without a prescription.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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.
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
Notable Effects & Ingredients
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.
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!
Ingredients Related to Skin Types
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.
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.
