Certain skincare products
Many anti-aging and acne products work by thinning the outer layer of skin or regulating the production of melanin, a natural pigment that acts as a barrier for sun protection, says Alok Vij, MD, a dermatologist at the Cleveland Clinic. Look at the labels: If a product contains retinols or vitamin A, glycolic or salicylic acid, or hydroquinone, your skin may be more susceptible to sun damage. Be especially vigilant about seeking out shade, applying sunscreen, and wearing protective clothing and hats. Speaking of sun protection, don’t miss these sunscreen myths that make dermatologists cringe.
