Dapsone Gel 5%
Dapsone Gel 5%
Product Description
Product overview
A prescription-strength topical gel featuring 5% dapsone, an antibacterial and anti-inflammatory sulfone antibiotic FDA-approved for the treatment of acne vulgaris. Applied twice daily, this gritty translucent gel targets inflammatory papules and pustules with minimal systemic absorption, making it a well-tolerated alternative for patients who cannot use retinoids or benzoyl peroxide.
Antibacterial Action
Dapsone is a sulfone antibiotic that suppresses the growth of acne-causing bacteria on the skin surface, reducing active breakouts.
Texture & feel
SENSORYAntibacterial Action
Dapsone is a sulfone antibiotic that suppresses the growth of acne-causing bacteria on the skin surface, reducing active breakouts.
Anti-Inflammatory
Reduces redness, swelling, and inflammation associated with papules and pustules, calming inflamed acne lesions.
Non-Retinoid, BPO-Free
An alternative for patients who cannot tolerate retinoids or benzoyl peroxide. Won't bleach clothing or linens.
Minimal Systemic Absorption
Topical application delivers ~1% of the systemic exposure compared to a 100mg oral dose, greatly reducing risk of hematologic side effects.
Safety & compatibility
SAFEFDA former Category C. No adequate human studies. Animal studies showed embryocidal effects at doses 250x+ the human topical exposure. Use only if benefit outweighs risk. Consult your doctor.
Oral dapsone passes into breast milk. While topical absorption is minimal (~1% of oral), the manufacturer advises against use during breastfeeding.
Contains no ferments, fatty acids, esters, or polysorbates. The minimal ingredient list is safe for fungal acne-prone skin.
Water-based gel formula with carbomer base. Rating 0/5 — will not clog pores.
Patients with glucose-6-phosphate dehydrogenase deficiency should have G6PD levels checked before use. Risk of hemolysis exists, though clinical trials showed no significant hemolytic events.
Rare postmarketing cases reported. Discontinue immediately if lips, nail beds, or skin turns gray or blue and seek medical attention.
Applying benzoyl peroxide together with dapsone gel may cause temporary yellow or orange discoloration of skin and facial hair. Allow drying time between applications.
Do not use with oral dapsone or antimalarial medications. TMP/SMX (Bactrim) increases dapsone metabolite levels and risk of hemolysis in G6PD-deficient patients.
Ingredient breakdown
INGREDIENTSDapsone (4,4'-Diaminodiphenylsulfone) 5%Proven
A synthetic sulfone antibiotic with both antibacterial and anti-inflammatory properties. Originally developed for leprosy treatment in the 1940s, it was reformulated as a topical gel for acne in 2005. It targets inflammatory acne lesions (papules and pustules) more effectively than comedonal acne.
- Clinical Trial: Two Phase III studies showed ~50% reduction in inflammatory lesions at 12 weeks vs. 42% with vehicle
- Long-Term: 12-month open-label study showed 58.2% mean reduction in inflammatory lesion counts
- Systemic Safety: Topical exposure is approximately 100-fold less than oral dapsone at therapeutic doses
- Female Benefit: Studies indicate dapsone gel may be particularly effective in female patients and those aged 18+
Carbomer Homopolymer Type CVehicle Base
A high-molecular-weight polymer used as the gel base. Provides the product's viscosity and helps the active ingredient remain on the skin surface for optimal delivery. It creates the characteristic gel texture.
- Function: Thickening agent, emulsion stabilizer, and gel-forming polymer
- Safety: Widely used in pharmaceutical and cosmetic formulations with an excellent safety record
Diethylene Glycol Monoethyl Ether (DEGEE)Penetration Enhancer
A solvent and penetration enhancer that helps dissolve dapsone and promotes its delivery into the skin. Also known as Transcutol, it is commonly used in topical pharmaceutical formulations.
- Function: Solubilizes dapsone in the gel matrix and enhances skin penetration
- Note: Contributes to the gritty texture when drug particles are not fully dissolved
MethylparabenPreservative
An antimicrobial preservative that prevents bacterial and fungal growth in the gel formulation, ensuring product stability throughout its shelf life.
- Function: Broad-spectrum preservative
- Safety: Used at low concentrations in pharmaceuticals; FDA-approved for topical drug products
6 ingredients
Dapsone 5% (active), Carbomer Homopolymer Type C, Diethylene Glycol Monoethyl Ether, Methylparaben, Sodium Hydroxide, Purified Water.
Where it fits in your routine
ROUTINEApply to clean, dry skin before moisturizer. Use twice daily (AM & PM). Allow gel to absorb fully before layering other products. If using benzoyl peroxide, apply at a separate time to avoid yellow/orange discoloration.
How to use
HOW TO USECleanse
Gently wash the affected area with a mild cleanser and pat dry. Do not scrub or use harsh exfoliants beforehand.
Apply a Pea-Sized Amount
Squeeze approximately a pea-sized amount of Dapsone Gel 5% onto your fingertip. The gel may appear gritty with visible particles — this is normal.
Spread in a Thin Layer
Apply in a thin layer to the acne-affected areas only. Rub in gently and completely until the gel is absorbed.
Wash Hands
Wash your hands immediately after application. Avoid contact with eyes, lips, and mucous membranes.
Continue Your Routine
Wait 1–2 minutes for absorption, then apply moisturizer and sunscreen (AM). Use twice daily. Allow up to 12 weeks for full results.

Frequently asked questions
FAQDapsone Gel 5% is former FDA Pregnancy Category C — meaning risk cannot be ruled out. There are no adequate human studies for topical dapsone in pregnant women. Animal studies at very high oral doses (250x+ human topical exposure) showed embryocidal effects. Use only if the potential benefit justifies the potential risk to the fetus. For breastfeeding, the manufacturer advises against use, as oral dapsone is known to pass into breast milk and may cause hemolytic reactions in nursing infants. Although topical absorption is minimal (~1% of oral dose), consult your doctor before using during pregnancy or while breastfeeding.
Yes. Dapsone Gel 5% has a very minimal ingredient list (only 6 ingredients) and contains no fermented ingredients, fatty acids, fatty esters, polysorbates, or oils that feed Malassezia yeast. The water-based carbomer gel vehicle is considered safe for fungal acne-prone skin. This makes it one of the few prescription acne treatments that is both effective against bacterial acne and compatible with fungal acne concerns.
Dapsone Gel 5% can generally be used alongside retinoids (tretinoin, adapalene), vitamin C, and chemical exfoliants (AHA/BHA). In fact, studies have shown that combining dapsone with adapalene enhances efficacy, achieving ~51% total lesion reduction vs. 39% with dapsone alone. However, the most important interaction to be aware of is with benzoyl peroxide — applying BPO directly after dapsone can cause temporary yellow or orange skin discoloration. If you use both, apply them at different times of day or allow dapsone to fully dry first. Always introduce new actives gradually and consult your dermatologist.
Dapsone Gel 5% is best suited for oily, combination, and acne-prone skin types. Its water-based gel formula absorbs quickly without leaving a greasy residue. It is particularly effective for adult women with hormonal acne along the jawline, chin, and cheeks. Sensitive skin types generally tolerate it well — it is less irritating than retinoids and benzoyl peroxide. Dry skin types may experience additional dryness (reported in ~16% of users) and should pair it with a hydrating moisturizer.
Many users report noticing improvement within 1–2 weeks, particularly reduced redness and inflammation. Clinical studies show approximately 30.6% reduction in inflammatory lesions by 4 weeks. The full evaluation period is 12 weeks — if no improvement is seen by then, your dermatologist should reassess your treatment plan. Long-term studies show continued improvement up to 12 months with 58.2% reduction in inflammatory lesions. Some users experience an initial purging period where breakouts temporarily worsen before improving.
Apply Dapsone Gel 5% to clean, dry skin as the first treatment step after cleansing. Let it absorb for 1–2 minutes, then follow with any other serums, moisturizer, and sunscreen (AM). For the PM routine, apply after cleansing and before moisturizer. If using retinoids, you can apply dapsone in the morning and retinoid at night, or apply them at the same time — they are compatible. Avoid layering benzoyl peroxide directly on top of dapsone to prevent temporary skin discoloration.
No. Dapsone Gel 5% has a comedogenic rating of 0/5. Its water-based gel formula contains no oils, waxes, silicones, or fatty ingredients that could clog pores. The base consists of carbomer (a gel-forming polymer), a solvent (DEGEE), a preservative (methylparaben), a pH adjuster (sodium hydroxide), and purified water. This makes it one of the least comedogenic prescription acne treatments available.
Dapsone Gel 5% should be used according to the expiration date printed on the tube packaging. The product is generally stable for up to 24 months when stored properly at controlled room temperature (20°–25°C / 68°–77°F). Protect from freezing. A 60g tube typically lasts about 3 months when used twice daily with a pea-sized amount. Always replace the cap tightly after each use.
Verdict: Dapsone Gel 5% by Encube Ethicals is a well-tolerated, FDA-approved prescription treatment for mild to moderate inflammatory acne. It stands out as a non-retinoid, non-BPO alternative that won't bleach your fabrics or cause severe irritation. It is particularly effective for adult women with hormonal acne and those with sensitive or fungal acne-prone skin. While it takes up to 12 weeks for full results and is less effective against comedonal acne compared to retinoids, its minimal ingredient list, low comedogenicity (0/5), and favorable side-effect profile make it a valuable option in the acne treatment toolkit. The generic Encube version offers significant cost savings over brand-name Aczone. Best used as part of a comprehensive skincare routine under dermatologist supervision.

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.

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.
