acne scars

Acne scars are the marks or indentations left on the skin after severe acne lesions heal. They occur when the skin's collagen, a protein that provides structure and firmness, is damaged during inflammation. This damage can cause the skin to heal unevenly, resulting in areas that are either indented (atrophic scars) or raised (hypertrophic scars). Factors like genetics, the severity of acne, and how the skin heals influence scar development. While scars are permanent, various treatments such as topical creams, laser therapy, and microneedling can help improve their appearance and promote smoother skin.
