Redness After 18% Salicylic Acid Peel

Superficial redness may occur after a salicylic acid peel. This redness usually subsides within days. If the redness lasts, a pulsed dye laser is recommended by our clinic. Dr. Karamanoukian 

You have had a normal response to the peel.  Wash with a gentle cleanser and keep your skin moist with Aquaphor.  Once you have stopped peeling after about one week, your skin will be pink.  Wear sun protection and avoid the sun as much as possible for at least one month to prevent pigmentation.

Usually after a 18% salicylic peel the skin has red/brown blotchy areas for 1-3 days. You may begin to notice some peeling around the mouth on day 2 or 3. Peeling continues for 5-7 days. Not all of the peeling is noticable, especially on the sides of the face. A noncomedogenic moisturizer and a physical sun block (SPF 30) should be used during this recovery period.

I tell my patients to wear a large brimmed hat to keep sun off the face and apply Vanilpy or Aquaphor Healing Ointment frequently until the skin heals.

Salicylic acid peels up to 30%, in general, are safely used in people of all skin pigmentation types.  From what I can see in your pictures, you have a very normal amount of red/brown color that I would expect to see 24 hours after your peel.  Any dark spots you had to begin with tend to get darker before they peel.  Redness and darkening can last for 4-7 days while the peeling takes place.  Areas around the mouth, eyes, and nose tend to peel first.  I think you will be very pleased with your peel based on your skin's reaction so far, and I would be surprised if you developed any hyperpigmentation.  However, it's very important that you keep they areas moist with a cream or ointment (e.g. CeraVe or Aquaphor), use a gentle cleanser like Cetaphil, avoid picking, avoid rigorous exercise while peeling, and use at least SPF 30 sunblock consistently.
