Discolorations of the skin are very common and are mostly caused by the effects of the sun, wind, as well as from dryness or irritations that are accumulated over time. The differences in your skin tone can usually be covered with makeup, such as foundations, tinted moisturizers and concealers. If you’re considering a more rigorous approach, agents such as glycolic acid, kojic acid and hydroquinone can gradually lighten your skin and fade areas of discoloration and hyperpigmentation, such as age spots, liver spots, and freckles. Also, look for exfoliating ingredients in moisturizers and cleansers that gently encourage skin cell turnover by sloughing off the dead layers and improving your skin’s texture.
