What Sunscreen Does for Your Skin
Sunscreen helps protect your skin from the sun. The sun gives off UVA rays and UVB rays. UVA rays can lead to early aging. UVB rays can lead to sunburn. Both can harm your skin over time.

What Vitamin C Does for Your Skin
Vitamin C is an antioxidant. This means it helps fight free radicals. Free radicals are unstable molecules that can damage skin cells. They can come from sunlight. They can also come from pollution and smoke.
Vitamin C may help brighten dull skin. It may also help with dark spots and uneven skin tone. It supports collagen health too. Collagen helps skin look firm and smooth. Research shows that vitamin C plays an important role in skin health and photoaging support.
