Hello, Faceclin gel has clindamycin phosphate and nicotinamide as active ingredients. Clindamycin phosphate is an antibiotic with activity against Propionibacterium acnes, the acne causing bacteria and is nicotinamide is anti-inflammatory in nature. Supatret has Tretinoin which is a topical retinoid and this regimen is effective for mild moderate acne. If you have more number of inflammatory lesions and pustules, an oral antibiotic like Azithromycin or Doxycycline can also be added. Side effects of Tretinoin include burning sensation, redness and dryness. You can apply a moisturizer to your treatment like Neutrogena oil free moisturizer or Acnemoist cream. If there is lot of irritation or dryness you can switch to Adapalene instead of Tretinoin (Supatret). Supatret helps in acne scars mildly. Best treatment option include lasers and peels for atrophic/depresssed scars and for post acne hyperpigmentation kojic acid or azelaic acid combinations. Hope I have answered your query. Let me know if I can assist you further. Regards
