hi im dr satya.
welcome to health care magic,
sorry to hear that the chemical peel was responsible for the pigmentation.
over energetic chemical peel may be responsible for this, the best results are obtained when you dont meddle with the pigmentation and apply calmine lotion which acts as a mild sunscreen. application of 6 % glycolic acid
and kojic acid
over the pigment has some benefit.
please do not get depressed as this pigmentation is usually transient.
protect from sunlight
things will change, for the better.
feel free to contact.
