Hello. Thank you for writing to us at healthcaremagic Acne naturally reduce in severity over time but if not taken care of properly they might leave pigmentation and acne scars as sequelae. Acne is a chronic and recurring problem. Therefore it is important to take adequate care and not allow them to turn aggressive. Treatment of acne may stretch to months or even years and need to be modified at regular intervals according to severity of acne. Treatment of acne is guided by the severity. Topical treatment is usually enough for mild acne whereas for severe acne Oral treatment is usually combined with topical treatment. Topical treatment mainly comprises topical antibacterials like clindamycin; topical benzoyl peroxide and topical retinoids like adapalene. These topical treatments may be combined to produce additive results. Oral treatment comprises either Oral antibiotic e.g Doxycycline Or Oral retinoids like Isotretinoin. Once you acne activity is well controlled, it is still advisable to use a topical retinoid e.g adapalene gel as a maintenance treatment for acne till at a certain age when acne activity naturally dies down. Topical retinoids are antiinflammatory and comedolytic in action & therefore ideal for maintenance. Topical retinoids also hep to lighten pigmentation resulting from acne. I suggest you to visit a dermatologist. Your dermatologist will assess the severity of your acne and advice accordingly. Regards
