Acne scars are marks left on the skin after acne has healed. They can appear as indentations, raised areas, or discoloration, depending on the type of acne and how the skin reacted. These scars can affect anyone who has had severe acne, and they may cause feelings of self-consciousness or frustration. There are different treatments available for acne scars, including laser therapy, chemical peels, and microdermabrasion. These methods aim to improve the skin's appearance by promoting new skin growth and reducing the visibility of scars. Consulting a dermatologist can help determine the best option for individual skin types and concerns.
