Best Acne Treatments: 5 Top Options Compared (2026)

5 Acne Medications Compared — Summary Table

Choosing the right acne medication for your specific symptoms is the most important first step in acne treatment. The table below compares the 5 most popular topical acne medications curated by Intimo Life, covering comedonal, inflammatory, and pigmented acne.

All 5 medications are controlled drugs in Thailand, sold at licensed pharmacies with pharmacist consultation.

What Each Medication Is and How to Choose

1. Benzac AC (Benzoyl Peroxide) — Comedonal Acne + Oil Control

Benzac AC contains Benzoyl Peroxide at 2.5% or 5%. It works in three ways: kills Cutibacterium acnes bacteria, removes dead skin cells that clog pores, and reduces excess oil production.

2.5% vs 5%? Similar efficacy for mild-to-moderate acne, but 2.5% is significantly less irritating. Always start with 2.5%.

Best for: Whiteheads, blackheads, mild-moderate inflammatory acne, oily skin

How to use: Apply thinly over the affected area (not spot-only). Start with every other evening in week 1, gradually increase to daily.

2. Skinoren (Azelaic Acid 20%) — Acne + Dark Spots + Melasma

Skinoren Cream contains Azelaic Acid 20%, a natural grain-derived acid with three-in-one action: clears comedones, reduces acne bacteria, and inhibits melanin — reducing post-inflammatory hyperpigmentation and melasma.

Key advantage: Pregnancy Category B (consult doctor first) and does not photosensitize like retinoids.

What not to combine: Avoid on broken skin or near eyes/mouth/nostrils. Use cautiously with other irritating actives.

How to use: Apply thinly twice daily (morning and evening). Follow with moisturizer and SPF in the morning.

3. Acnetin-A (Tretinoin) — Gen 1 Retinoid, Strong Action

Acnetin-A Cream contains Tretinoin (Vitamin A acid), a first-generation retinoid. Speeds skin cell turnover, clears deep comedones, and reduces post-acne dark spots. Available in 0.025% and 0.05%.

⚠️ Important warnings:

• Pregnancy or trying to conceive: DO NOT USE
• Skin will be red, peeling, dry in weeks 2-4 (Retinization) — this is normal
• Greatly increases sun sensitivity — daily SPF 30+ is mandatory
• Do not combine with Differin (double retinoid)

How to use: Evenings only (Tretinoin degrades in sunlight). Week 1: every other day. Use pea-sized amount across full face.

4. Differin Gel (Adapalene) — Gen 3 Retinoid, Less Irritating

Differin Gel contains Adapalene 0.1%, a third-generation retinoid. Advantages over Tretinoin: 30-50% less irritating, photostable, and combinable with Benzac.

How to use Differin?

1. Cleanse and pat dry
2. Wait 20-30 minutes for skin to fully dry (reduces irritation)
3. Apply pea-sized amount across face (not spot treatment)
4. Once daily (evening recommended for beginners)
5. Follow with moisturizer

Best for: Comedonal acne on sensitive skin that can't tolerate Tretinoin, first-time retinoid users, acne + early anti-aging

Cautions: Pregnancy contraindicated, peeling/redness in weeks 1-2, daily SPF required.

5. Clinda-M (Clindamycin 1%) — Inflammatory + Pustular Acne

Clinda-M contains Clindamycin Phosphate 1%, a topical antibiotic that kills C. acnes and reduces follicular inflammation.

⚠️ Important notes:

• Use beyond 8-12 weeks may cause antibiotic resistance — pair with Benzoyl Peroxide to reduce risk
• Stop when active acne clears — not for daily maintenance like retinoids

Best for: Inflammatory acne (pustules, papules, redness), spot pus-filled lesions, adjunct to Benzac

How to use: Apply thinly to inflamed areas twice daily (morning and evening). Standard combo: Benzac morning, Clinda-M evening.

Decision Tree — Which Medication for Your Acne?

If you're unsure which medication to choose, use the table below as your starting point. Match your acne symptoms to the recommended options.

Can They Be Combined + Application Order

✅ Recommended Combos

• Benzac (morning) + Differin (evening) — standard combo
• Benzac (morning) + Clinda-M (evening) — severe inflammatory acne
• Skinoren (morning) + Differin (evening) — acne + dark spots

❌ Combos to Avoid

• Tretinoin + Differin — double retinoid, severe irritation
• Tretinoin + Benzoyl Peroxide at the same time — Benzac degrades Tretinoin (apply at different times)
• Clinda-M alone for 8+ weeks — antibiotic resistance risk

Application Order in Skincare

1. Cleanse with gentle cleanser
2. Toner (if used)
3. Acne medication (wait 20-30 min if using retinoid)
4. Moisturizer
5. SPF 30+ sunscreen (morning only — mandatory if using retinoid or Benzac)
