Applying sunscreen actually blocks harmful UV rays from penetrating the skin and triggering skin disorders. It also shields your skin from developing signs of aging, such as wrinkles and fine lines. Studies reveal that sunscreen users below the age of 55 had 24% lesser chances of developing these aging signs than users who didn’t use non-sunscreen or used it occasionally. The essential skin proteins, such as collagen, keratin, and elastin are protected by sunscreen. These proteins are required for keeping the skin smooth and healthy. Make sure your sun block has titanium oxide in it as this ingredient is crucial for your skin.
