Hi Thanks for your query. Acne can cause red or brown discoloration and uneven skin contour. Usually multiple types of treatments are needed for maximum improvement. Patience is key since the full effect is often not seen for several months. Skin discoloration and texture can be improved with topical treatments like hydroquinone and Retin-A, but for deeper scars and more significant discoloration, other techniques are needed. Small, deep acne scars can be treated with surgical excision, which will ideally trade a depressed and discolored scar for a thin, flat scar.This is often followed by other resurfacing techniques like laser, chemical peel or dermabrasion to further smooth the skin and minimize scarring.
