How do glycolic acid and salicylic acid help with acne and acne scars?

My other colleagues have answered well and indeed, it appears that there is a cystic lesion underneath and the evidence of discharge suggests you need urgent medical attention. Steroid injection and antibiotics should probably be the mainstay of the therapy. In terms of other changes to your skin care, please ensure you are using a light gel based moisturiser in view of the oily skin, and please use the appropriate concentration of rectanyl(and don't be overly generous as what my patients love to do unilaterally).

A multimodal approach is often needed to remove acne scars. These can include: subcision TCA CROSS and punch excision with microsurgery apart from laser treatments Acne scars can be depressed or raised, with or without discoloration. Examples of depressed scars are ice pick scars, box scars and rolling scars. Raised scars are called hypertrophic or keloid scars, which result from an overproduction of collagen. Sometimes, a red or brown discoloration remains after acne has healed, and these are called post-inflammatory erythema (red) and post-inflammatory hyperpigmentation (brown).
