The colour of the skin is determined by the amount of melanin produced in the skin. This in turn is influenced by genetic factors, sun exposure, drugs etc. Uneven skin tone, or any other pigmentation which is acquired and not genetic can be treated with various depigmentation creams which are to be used as per Dermatologist’s prescription. Sunscreens are mandatory to protect the skin from tan and other signs of some damage. Procedural treatments like chemical peels, laser toning etc are recommended apart from topical creams to treat the pigmentary concerns. It is not advised to use OTC creams claiming improvement in skin pigmentation without professional advice. Face washes can never treat pigmentation. They can only help clean excess oil, dirt and grime collected over the skin. For oily skin, one can use, salicylic acid, glycolic acid or tea tree oil based facewashes.
