All sunscreens are not created equal, which is why it’s especially important to choose a broad spectrum sunscreen. A broad spectrum sunscreen protects the skin from both UVA and UVB rays, and when used as directed, a daily-use facial sunscreen can help prevent the sun damage that contributes to premature signs of aging, as well as skin cancer.

UVA rays are consistently strong throughout the year and are responsible for the appearance of skin wrinkling, discoloration, and loss of elasticity. These rays can penetrate clouds, glass, and the upper layers of skin causing damage to valuable proteins like collagen and elastin that give the skin its volume and structure. UVA damage is a threat to the skin year-round, even on overcast days, when you are driving, or when you’re indoors near a window.
