Will self-tanner make my melasma worse?
The good news is no! All the self tanners so far contain the same active ingredient (DHA) and they do not affect the pigment making cells (melanocytes) one way or the other. They just “stain” temporarily the outer dead layer of the skin (epidermis). They are very safe unless you are allergic to one of the ingredients, most commonly in the base cream. Dr. I
