Sunscreen. “Sunscreen is always going to be essential to protect against environmental aggressors, and some sunscreens may offer protection against UVA, UVB, and blue light,” says Marisa Garshick, MD, FAAD.
Antioxidants. “Antioxidants are key for preventing damage from environmental aggressors because they pair with free radicals that are looking to ‘steal’ electrons from other molecules, thus neutralizing the damage,” says Engelman. “Vitamin C is particularly effective at preventing and combating damage from environmental aggressors because of its exfoliating properties, which both brighten the skin (reducing hyperpigmentation) and boost collagen production by stimulating cell turnover. Skincare products that are rich in antioxidants, specifically vitamin C, are excellent for protecting skin from environmental aggressors.”
Moisture. “Aggressive temperature changes can damage the skin barrier, so in the winter, remember to utilize your moisturizer and humectants, and during the summer, use your hydrating serums and toning mists to keep your skin cool,” says Shokeen.
