Acne scars are a general term used to describe pigmentation, contour irregularities, pits, or scarred skin resulting directly from acne and inflammation. The treatment depends directly on the type of scar. Scars can have any of the above-mentioned components.
Glyquin or other hydroquinones work well to eliminate pigmentation as a result of acne and inflammation. The product does not reach the deeper skin layers and is thus not effective in reducing or improving contour irregularities and deep pits.
