What it is

Dapsone gel is a topical acne medication containing dapsone, an anti-inflammatory and antibacterial compound originally used in systemic form for infections and immune conditions. In topical gel form (commonly 5%), it helps treat inflammatory acne (papules, pustules, cysts) by reducing swelling, redness, and bacterial overgrowth without being as irritating as stronger treatments like high-strength benzoyl peroxide or oral isotretinoin.

In Korea, dapsone gel is often used in dermatology-supervised acne care plans, especially for patients with sensitive or adult acne who cannot tolerate harsher topicals.

Why it’s done

• Reduces inflammation → calms red, swollen acne lesions
• Antibacterial action → decreases Cutibacterium acnes (acne bacteria)
• Safe for sensitive skin → gentler than many retinoids or benzoyl peroxide formulations
• Suitable for adult or hormonal acne → effective on lower-face breakouts
• Adjunct to combination therapy → often used alongside retinoids, antibiotics, or oral treatments
• Pigmentation-friendly → less likely to worsen PIH (post-inflammatory hyperpigmentation), a key concern for Asian skin

Alternatives

• Benzoyl peroxide (BPO) → powerful antibacterial, but more irritating
• Retinoids (adapalene, tretinoin) → strong pore uncloggers, but high irritation risk
• Azelaic acid → antibacterial + pigmentation brightening, but less anti-inflammatory than dapsone
• Topical antibiotics (clindamycin, erythromycin) → effective short-term, but resistance risk
• Oral medications → isotretinoin, hormonal therapy for severe or resistant acne

Korean dermatologists often recommend dapsone gel for patients who want a gentler yet effective alternative to benzoyl peroxide or retinoids.

Preparation

• Skin assessment → dermatologist determines acne type (inflammatory vs comedonal vs cystic)
• Medical history check → important if patient has G6PD deficiency (rare blood condition that can be affected by dapsone)
• Routine simplification → avoid starting with multiple new strong actives at once
• Patch testing → apply on a small area first to rule out sensitivity

How it’s Done

Application guidelines

• Use on clean, dry skin once or twice daily as directed
• Apply a thin layer to affected acne areas (not just single spots if breakouts are widespread)
• Start with once daily to monitor tolerance, then increase if no irritation
• Combine with a non-comedogenic moisturizer to prevent dryness
• Always use SPF in the daytime (to prevent acne marks and PIH)

Combination strategies in Korea

• Dapsone gel + Retinoid (alternate use) → reduces irritation while keeping acne under control
• Dapsone gel + Azelaic acid → calms redness + brightens pigmentation
• Dapsone gel + Niacinamide serum → improves barrier + reduces oil and inflammation
• Dapsone gel + LED blue light therapy → clinic-based add-on for bacterial suppression

Recovery

• 2–4 weeks → inflammation and redness of acne start improving
• 6–8 weeks → fewer new pimples, calmer skin tone
• 3–6 months → long-term control of acne with reduced scarring and pigmentation risk

Korean dermatology clinics often combine dapsone gel plans with:
✔️ Oil-control cleansers
✔️ Barrier-repair moisturizers
✔️ Gentle exfoliation (salicylic acid or mandelic acid, 1–2x per week)
✔️ Clinic treatments (pico laser, acne scaling, LED light)

Complications

• Mild dryness, redness, or peeling (less common than with retinoids or BPO)
• Orange-brown discoloration if combined with benzoyl peroxide (cosmetic but harmless)
• Rare allergic reaction
• Contraindicated in patients with G6PD deficiency

Treatment Options in Korea

How dapsone gel is used in Korean dermatology

• Usually prescribed for adult women with hormonal acne
• Recommended for patients with sensitive skin that cannot tolerate benzoyl peroxide
• Combined with oral supplements (zinc, vitamin D, omega-3s) for better outcomes

Clinic-based protocols

• Moderate acne → dapsone gel + retinoid (adapalene) at night + salicylic acid cleanser
• Hormonal acne → dapsone gel + oral therapy (spironolactone or hormonal balance supplements)
• Acne with pigmentation → dapsone gel + azelaic acid cream + SPF cushion reapplication
• Post-acne scarring → dapsone gel + clinic RF microneedling or laser toning

Popular Korean brands
Since dapsone is more often prescription-based, it’s dispensed through dermatology clinics and pharmacies in Korea. Some clinics prepare customized compounded gels combining dapsone with soothing agents (like panthenol or centella extract).

Key Point
