I had a chemical peeling 2 weeks back .My skin has grown black and the skin is peeling very slowly .Should I use my hand to peel off the skin or it will be peeled off? It is shown more black than before and it's almost 2 weeks, I took this treatment and it's peeling very slowly. Will the blackness after the treatment go away once the skin got peeled off/ What should I do? This is my third sitting of chemical peel and I had taken it on my arms.
