Acne scars can be improved significantly, but the best treatment depends on the type and depth of the scars. For mild marks and dark spots, simple options like retinoid creams, chemical exfoliants (such as glycolic acid), vitamin C, and daily sunscreen can help gradually smooth and lighten the skin. For deeper or pitted scars, clinic-based treatments give better results, including chemical peels, microneedling, laser therapy, and procedures like subcision or fillers that help rebuild collagen and even out the skin surface. Often, a combination of treatments over time works best rather than a single solution. It is important to avoid picking pimples and to treat active acne early to prevent new scars. Consulting a dermatologist is recommended so they can assess your skin and create a personalised plan for the best and safest results.
