Is ochemical peel good for our skin and where can I get it?

Depends... ...On the type of peel. They range from very mild, for a "freshening" effect, to very strong, for removal of age spots and shallow wrinkles, to phenol, which is so strong it is dangerous if not done correctly. Many dermatologists do them. Some "spas" do them in some states, but i would strongly discourage subjecting your face to exposure to harsh chemicals by anyone except a well-trained doctor.
