Treatment

UV rays help stimulate the production of melanin, which is what causes dark spots on your skin. While you may want to fight those spots now, Shamban says you have to be exceptionally careful about how you do that. "Be very careful if you use products with AHA's (alpha-hydroxy acids) or retinol. These products can lead to discoloration and hyperpigmentation, so you must stay out of the sun if you use them," she says. A better option is to choose treatment products that use natural, non-acid ways of brightening your skin, as they will not make you super-sensitive to the sun.
