Dapsone Gel 5%
Dapsone Gel 5%
Product Description
Product overview
Taro Dapsone Gel 5% is a prescription-strength topical antibiotic and anti-inflammatory gel formulated to treat acne vulgaris in adults and adolescents 12 years and older. Containing 50 mg of dapsone per gram in a lightweight, fast-absorbing gel base, it targets inflammatory lesions without the antibiotic resistance concerns associated with traditional topical antibiotics. A generic equivalent of Aczone® 5%, it delivers the same clinically proven active at a more accessible price point.
Dual-Action Anti-Acne Formula
Dapsone 5% works as both an antimicrobial and anti-inflammatory agent, tackling the two key drivers of acne vulgaris simultaneously — bacteria and redness.
Texture & feel
SENSORYDual-Action Anti-Acne Formula
Dapsone 5% works as both an antimicrobial and anti-inflammatory agent, tackling the two key drivers of acne vulgaris simultaneously — bacteria and redness.
No Antibiotic Resistance Risk
Unlike clindamycin or erythromycin gels, dapsone is a sulfone, not a traditional antibiotic, so P. acnes resistance is not a documented concern with this class.
Non-Drying, Gentle Vehicle
The minimal 6-ingredient gel base is designed to minimize irritation. Clinical studies show lower rates of dryness and peeling compared to retinoid-based gels.
Makeup-Friendly Formula
Absorbs quickly and leaves no greasy residue. Goes smoothly under oil-free moisturizers and foundations — ideal for daily wear on acne-prone skin.
Affordable Generic of Aczone®
Taro's dapsone gel carries an AB therapeutic equivalence rating to Aczone® 5%, meaning identical clinical efficacy at a fraction of the brand-name price.
Clinically Studied Efficacy
Two pivotal randomized controlled trials demonstrated up to 54% reduction in inflammatory lesion counts over 12 weeks vs. vehicle, meeting FDA approval standards.
Safety & compatibility
SAFEFDA pregnancy category C. No adequate controlled studies in pregnant women. Animal studies with oral dapsone showed embryocidal effects at very high doses. Use only if potential benefit justifies the risk — always consult your doctor.
Dapsone gel can pass into breast milk. Systemic absorption from the topical gel is approximately 1% of an oral dose, but the manufacturer advises against use while nursing. Discuss alternatives with your healthcare provider.
The formula contains no ferments, polysorbates, fatty acids, esters, or other ingredients known to feed Malassezia. Confirmed fungal acne safe by skinsort.com community analysis.
None of the inactive ingredients are known pore-cloggers. Carbomer, ethoxydiglycol, and methylparaben all score 0–1 on the comedogenic scale. Safe for acne-prone skin.
Patients with glucose-6-phosphate dehydrogenase deficiency may be at elevated risk for hemolysis. Hemolytic anemia is less likely with topical than oral dapsone, but G6PD patients should be monitored.
Applying benzoyl peroxide immediately after dapsone gel can cause a temporary yellow-orange discoloration of skin and facial hair. Allow dapsone to fully absorb, or use BPO at a different time of day.
Dapsone is not a retinoid and does not increase photosensitivity. Sunscreen is still recommended as part of any acne treatment routine to protect healing skin.
Rare cases of methemoglobinemia have been reported postmarketing. Risk is very low with topical use but increased in combination with certain oxidizing medications. Seek care if you experience blue-gray lips or difficulty breathing.
Ingredient breakdown
INGREDIENTSDapsone (Active) 5% / 50 mg per gramProven
The star ingredient. Dapsone (4,4'-diaminodiphenylsulfone) is a sulfone compound with dual antimicrobial and anti-inflammatory properties. Originally used systemically for leprosy and dermatitis herpetiformis, it was repurposed as a topical acne treatment due to its ability to reduce inflammatory acne lesions with minimal systemic absorption.
- Mechanism: Inhibits dihydropteroate synthase in bacteria; also suppresses neutrophil-driven inflammation at the follicular level.
- Clinical Data: Two pivotal RCTs (Draelos et al., JAAD 2007) showed ~48–54% reduction in inflammatory lesion counts at 12 weeks vs. vehicle.
- Systemic Exposure: Topical 5% gel produces blood levels ~100x lower than a 100 mg oral dose, making systemic side effects rare.
- Resistance: No documented P. acnes resistance to dapsone in topical form, unlike clindamycin or erythromycin.
Carbomer (Carbomer Homopolymer Type C) <1%Proven
A high-molecular-weight polymer of acrylic acid that functions as the primary gelling agent in this formulation. Carbomer creates the characteristic smooth, spreadable gel texture and helps suspend the dapsone drug substance evenly throughout the base. Due to its large molecular size, carbomer has minimal skin penetration and is considered an inert, well-tolerated excipient.
- Function: Gelling agent, viscosity builder, formula stabilizer.
- Comedogenic Rating: 0 — does not clog pores.
- Safety: Extensively reviewed; considered safe at concentrations up to 1% in leave-on products by the Cosmetic Ingredient Review (CIR).
Ethoxydiglycol (Diethylene Glycol Monoethyl Ether) Solvent baseProven
A synthetic solvent also known as DGME (diethylene glycol monoethyl ether, NF). Its primary role is to dissolve dapsone, which is practically insoluble in water, and to carry the active ingredient into the follicular unit where it exerts its effect. Ethoxydiglycol also contributes to the gel's smooth application and quick-dry feel.
- Function: Solvent, penetration enhancer, improves dapsone bioavailability in the formulation.
- Skin Feel: Contributes to fast absorption and the non-greasy finish characteristic of this gel.
- Safety: Approved as a pharmaceutical excipient (NF grade); well-tolerated in topical products at standard concentrations.
Methylparaben <0.1%Proven
A widely used antimicrobial preservative from the paraben family. Methylparaben prevents microbial contamination (bacteria, yeast, mold) to ensure product safety and shelf stability. In pharmaceutical formulations, it is used at very low concentrations — typically 0.05–0.1% — well below concentrations shown to cause sensitization in most individuals.
- Function: Broad-spectrum preservative against gram-positive bacteria, fungi, and mold.
- Concentration: Used at pharmaceutical grade (NF) at levels far below sensitizing threshold.
- Safety Status: Approved by FDA, EMA, and CIR at standard concentrations; ongoing research into estrogenic activity remains inconclusive at typical topical doses.
Water (Purified Water, USP) Base / SolventProven
Purified water, USP grade (United States Pharmacopeia standard), serves as the primary aqueous solvent and vehicle for the gel formulation. It dissolves water-soluble excipients and, together with carbomer and ethoxydiglycol, forms the stable gel matrix that delivers dapsone to the skin.
- Function: Primary solvent, hydration vehicle, base for gel matrix formation.
- Grade: Purified Water USP — pharmaceutical-grade, free from contaminants.
Sodium Hydroxide pH Adjuster (trace)Proven
Also known as lye or caustic soda, sodium hydroxide is used in trace amounts purely to adjust the pH of the finished gel to an optimal range (approximately 6.0–7.0). Proper pH is critical for carbomer to form an effective gel structure and for dapsone to remain chemically stable throughout the product's shelf life.
- Function: pH adjustment, carbomer neutralization/gel formation.
- Final Product: Reacts completely with carbomer and water — no free sodium hydroxide remains in the finished product.
- Safety: At trace pH-adjusting levels, considered non-irritating and safe in finished formulations.
6 ingredients
Active: Dapsone 5% (50 mg/g)
Inactive: Carbomer Homopolymer Type C, Diethylene Glycol Monoethyl Ether (Ethoxydiglycol), Methylparaben, Purified Water, Sodium Hydroxide
Where it fits in your routine
ROUTINEApply Dapsone Gel 5% to clean, dry skin before moisturizer. Use AM and PM as directed by your prescriber. Allow to fully absorb before applying benzoyl peroxide to avoid temporary skin discoloration.
How to use
HOW TO USECleanse Your Face
Gently wash your face with a mild, non-stripping cleanser. Pat skin dry — do not rub vigorously. Allow skin to cool and dry fully before applying the gel.
Dispense a Pea-Sized Amount
Squeeze approximately a pea-sized amount (roughly the size of your fingertip) of Taro Dapsone Gel 5% from the tube. This amount is sufficient to cover the full face.
Apply in a Thin Layer
Gently rub the gel in completely over acne-affected areas of the face. A thin, even layer is all that is needed. The gel may appear gritty due to visible dapsone drug particles — this is normal.
Allow to Absorb, Then Moisturize
Wait for the gel to fully absorb (approximately 30 seconds to 1 minute). Follow with an oil-free, non-comedogenic moisturizer. In the morning, finish with a broad-spectrum SPF 30+ sunscreen.
Wash Hands Thoroughly
Wash your hands well after application to avoid accidental contact with eyes, mouth, or other sensitive areas. Avoid contact with eyes, lips, and mucous membranes.
Use Twice Daily (AM & PM)
Apply morning and evening as directed by your prescriber. If no improvement is seen after 12 weeks, consult your dermatologist to reassess your treatment plan.

The gel vehicle is well-suited to combination skin — lightweight enough for oily T-zones and gentle enough for drier cheek areas. Can be applied only to affected areas.
Fragrance-free, alcohol-free, and free from harsh actives like AHAs or retinoids. Lower irritation profile than most acne treatments. Those with paraben sensitivity should patch test first.
Does not actively moisturize, but clinical dryness rates are low (16% in studies). Always follow with a good non-comedogenic moisturizer to maintain the skin barrier.
Well-tolerated on normal skin types experiencing breakouts. Minimal disruption to skin balance due to the simple, non-stripping gel formula.
Results timeline
3–6 MONTHSCalming of Active Inflammation
Some users notice a reduction in the redness and swelling around existing pimples within the first week. The anti-inflammatory action of dapsone begins working immediately, but visible clearing takes time. Skin may appear slightly drier initially.
~30% noticed early calmingReduction in New Breakouts
By the second to fourth week, many users report that fewer new inflammatory papules and pustules are forming. Existing blemishes begin to flatten. This is the phase where consistent twice-daily use is most critical.
~50% saw fewer new breakoutsMeasurable Lesion Count Reduction
Clinical studies show statistically significant improvement in inflammatory lesion counts by week 8. Users often report noticeably clearer skin and improved skin texture. Some experience a purging-like phase as skin normalizes.
~54% average lesion reduction notedSignificant Acne Clearance
The 12-week mark is the standard clinical endpoint. FDA pivotal trials showed a clinical success rate of approximately 40.5% vs. 32.8% with vehicle. Many users report substantially clearer skin and improved confidence by this stage.
~40% achieved clinical success at 12 weeksLong-Term Maintenance & Sustained Clarity
Long-term safety and efficacy studies (up to 12 months) confirm that dapsone 5% gel maintains its effectiveness and tolerability with continued use. No tachyphylaxis (decreasing effect over time) has been documented.

Budget-friendly alternatives (dupes)
DUPESAnother FDA-approved generic of Aczone® 5% with an identical formulation (same 6 ingredients at the same concentrations). Therapeutically equivalent (AB-rated). The closest true dupe — same active, same inactive base, different manufacturer.
A widely prescribed topical antibiotic gel for acne. Works on a similar antimicrobial principle but uses a true antibiotic (clindamycin) rather than a sulfone. Risk of P. acnes antibiotic resistance with long-term use. Does not contain dapsone. Good for short-term use or in combination with benzoyl peroxide.
A retinoid-based topical available OTC that targets comedones and inflammatory lesions via a different mechanism (retinoic acid receptor agonism). More effective for comedonal acne. More irritating with higher rates of dryness and peeling, especially initially. Does not require combination with BPO and is widely accessible without a prescription.

Frequently asked questions
FAQTaro Dapsone Gel 5% is classified as FDA pregnancy category C, meaning there are no adequate and well-controlled studies in pregnant women, and it should be used during pregnancy only if the potential benefit justifies the potential risk. Animal studies using oral dapsone at very high doses showed embryocidal effects, though these doses were far higher than topical human exposure. For breastfeeding, the manufacturer states the gel should not be used during nursing because dapsone can pass into breast milk, even though topical absorption is approximately 1% of an oral dose. Always consult your OB/GYN or dermatologist before using any prescription medication during pregnancy or breastfeeding.
Yes — Taro Dapsone Gel 5% is confirmed fungal acne safe. Its ultra-minimal formula of only 6 ingredients contains none of the substances known to feed Malassezia yeast: no ferments, no polysorbates, no fatty acids (C11–C24), no esters, no oils, and no PEG derivatives. The inactive ingredients (carbomer, ethoxydiglycol, methylparaben, water, and sodium hydroxide) are all malassezia-neutral. This makes it one of the safest prescription acne treatments for those dealing with concurrent fungal acne or pityrosporum folliculitis.
Dapsone gel 5% can generally be used alongside other skincare actives with some precautions. With benzoyl peroxide: apply them at different times of day (dapsone in the AM, BPO in the PM) because applying BPO directly over dapsone can cause a temporary yellow-orange skin discoloration. With retinoids (tretinoin, adapalene, retinol): no direct chemical incompatibility, but using both simultaneously increases the risk of dryness and irritation — start with one and introduce the second slowly. With vitamin C (L-ascorbic acid), AHAs (glycolic, lactic acid), and BHAs (salicylic acid): no known interactions, but monitor for cumulative irritation. Always discuss combinations with your dermatologist for a personalized plan.
Taro Dapsone Gel 5% is best suited for oily, combination, and acne-prone skin types. Its water-based gel formula is lightweight, oil-free, and non-comedogenic, making it ideal for those prone to breakouts who cannot tolerate heavier formulas. It is also well-tolerated by sensitive skin types due to its fragrance-free, alcohol-free composition and lower irritation profile compared to retinoids or AHA-based treatments. Dry skin types can also use it, but should follow with a good moisturizer to prevent any gel-related dryness.
Most users notice some initial calming of active inflammation within the first 1–2 weeks. Meaningful reduction in lesion count and visible clearing is typically observed between weeks 4 and 8 of consistent twice-daily use. The FDA pivotal clinical trials used a 12-week treatment period as the primary endpoint — this is the standard timeframe for assessing full efficacy. If no improvement is seen after 12 weeks of consistent use, consult your dermatologist to reassess your treatment plan. Do not stop treatment early if results are progressing, as skin continues to improve over the full course.
Apply Taro Dapsone Gel 5% as the first active treatment after cleansing and toning (if used), and before moisturizer and sunscreen. The correct order is: Cleanser → Toner (optional) → Dapsone Gel 5% → Moisturizer → Sunscreen (AM only). Allow the gel to absorb fully (about 30 seconds) before layering other products. If you also use benzoyl peroxide, apply dapsone in your morning routine and BPO in your evening routine to prevent the yellow-orange skin reaction that can occur when the two are applied consecutively.
No — Taro Dapsone Gel 5% is non-comedogenic with a comedogenic rating of approximately 1 out of 5. None of the inactive ingredients (carbomer, ethoxydiglycol, methylparaben, water, sodium hydroxide) are known pore-cloggers. The formula is oil-free and silicone-free, making it safe for acne-prone and pore-sensitive skin. It is specifically designed to treat acne without contributing to pore congestion.
Taro Dapsone Gel 5% should be used within 12 months of opening, and always before the expiration date printed on the tube and carton. Store at controlled room temperature (20°–25°C / 68°–76°F) away from heat, humidity, and direct sunlight. Protect from freezing. Do not store in the bathroom cabinet where temperature and humidity fluctuate. The 60g tube typically lasts 2–3 months with standard twice-daily full-face use; the 90g tube lasts approximately 3–4 months.
Verdict: Taro Dapsone Gel 5% is an excellent, clinically proven prescription acne treatment for those dealing with inflammatory acne vulgaris who want an effective option without antibiotic resistance risk, without the dryness of retinoids, and without the bleaching of benzoyl peroxide. Its ultra-minimal 6-ingredient formula is fungal acne safe, fragrance-free, oil-free, and non-comedogenic — ticking nearly every box for sensitive, acne-prone skin. As an AB-rated generic of Aczone®, it delivers the same FDA-proven active at a fraction of the brand cost. The main limitations are the prescription requirement, the 8–12 week timeline for results, and caution needed during pregnancy and for G6PD-deficient patients. For anyone whose dermatologist has recommended dapsone gel, the Taro generic is the smart, cost-effective choice.

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.
