Skin discoloration after chemical peel. Pink patch turned brown. Is this normal? (photo)

Hello and thank you for your question.  It looks as though this spot was treated aggressively, and/or the skin was peeled off prematurely.  With your skin type, you must be very careful when doing any aggressive treatments, as your skin has a tendency to hyperpigment after any sort of inflammation or trauma.  With this said, be sure to stay away from the sun as best you can.  Wear SPF daily with a wide brimmed hat if you are going to be out.  This discoloration, or post inflammatory hyperpigmentation, can take months to fade, however bleaching cream may help, however it is best to wait at least 6 weeks. Be sure you are being treated by an experienced practitioner.  Best of luck. 

A chemical peel removes outer layer of your skin to regenerate new skin. In your case, the peel has worked a little deeper creating deeper exfoliation and increased melanin/ pigment formation. The peeling is not too deep to create any permanent effect and will go away in 6-12 weeks with sun protection and skin lightening cream. Meet your treating doctor or a dermatologist for further course of treatment.

Hi!  Thank you for your question and picture.  This brown patch appears to be post-inflammatory hyperpigmentation.  It will fade with time....sometimes up to 12 weeks.  It may also peel away sooner.  In the meantime, sunscreen, sunscreen, sunscreen! Dr. Huo
