Facial sunscreen is an essential step in every daily morning skincare regimen, and broad-spectrum sunscreen protection is key for preventing the UV damage that contributes to premature signs of aging as well as skin cancer. Yet sunscreens alone don’t shield the skin from all free radicals generated by other environmental aggressors such as infrared rays and pollution that harm the skin. Using a daily topical antioxidant serum in conjunction with a broad-spectrum sunscreen provides an optimal level of skin protection that helps maintain skin health and prevent other unwanted skin changes.
