Chemical peels – Professionally-administered (don’t try it at home) chemical peels involve the use of acids to remove superficial areas of the skin. The strength of chemical peels varies from treatment to treatment but work best on people with lighter skin, because the acids used in the peel may cause darkening of the skin. It’s imperative that you talk with a dermatologist before using chemical peels for acne treatment if you have darker skin. The good news, however, is that people with darker skin can use OTC products that contain the same chemicals used in chemical peels (but at a lower percentage).
Acne scars are caused by inflammation within the dermal layer of skin and are estimated to affect 95% of people with acne vulgaris. The scar is created by abnormal healing following this dermal inflammation. Scarring is most likely to take place with severe acne, but may occur with any form of acne vulgaris. Acne scars are classified based on whether the abnormal healing response following dermal inflammation leads to excess collagen deposition or loss at the site of the acne lesion.
Acne removal: Your dermatologist may perform a procedure called “drainage and extraction” to remove a large acne cyst. This procedure helps when the cyst does not respond to medicine. It also helps ease the pain and the chance that the cyst will leave a scar. If you absolutely have to get rid of a cyst quickly, your dermatologist may inject the cyst with medicine.
