Acne scars are indentations or raised areas on the skin that are left behind after acne lesions have healed. They can occur as a result of severe acne or improper treatment of acne lesions. Acne scars can vary in size, shape, and appearance and may be accompanied by other symptoms, such as pain or sensitivity.

There are several different types of acne scars, including:

Atrophic scars: These are indentations in the skin that occur when collagen and other tissues are lost due to acne. Atrophic scars include rolling scars, boxcar scars, and icepick scars.

Hypertrophic scars: These are raised, bumpy scars that occur when excess collagen is produced in response to acne.

Keloid scars: These are raised, irregularly shaped scars that occur when excess collagen is produced in response to acne and spreads beyond the boundaries of the original wound.

Treatment for acne scars depends on the type and severity of the scars. Options may include topical creams, chemical peels, laser treatments, microneedling, and surgical procedures, such as punch excision or subcision. It is important to consult a qualified dermatologist or plastic surgeon to determine the best treatment plan for you.
