Dr. Kar: A good skincare routine might help; use a cleanser with salicylic acid, and exfoliate regularly. Also, try to use water-based or non-comedogenic makeup. To combat acne, use topical medication formulated with vitamin A derivatives.
On the advice of a doctor, you can also try these procedures to tackle severe acne and prevent scarring: photodynamic therapy, which uses a combination of medication and laser treatments to reduce bacteria and sebum production; dermabrasion, whereby the top layers of the skin are removed with a rotating brush; and the gentler microdermabrasion, which helps unclog pores and get rid of surface dead skin cells.
Another alternative is a chemical peel, which involves the use of a chemical exfoliant to clean out pores and remove the top layers of the skin, revealing less damaged skin underneath and thereby improving the look of scars.
