Chemical peelings are one of the best treatments for dark patches on the face. They are based on application of special exfoliating chemical solutions on the skin, with the purpose to remove its dead cells and to rejuvenate it.
Immediately after there is a little redness, which allows daily activities to take place. The point where the dark patches were, will gradually peel of for 4-7 days. The peel degree depends on the concentration of the chemical agent as well as the depth of the treatment.
