Protecting yourself from harmful UV rays should be a priority, therefore you should not step out without applying sunscreen.
You should always apply sunscreen before going out because:
It protects your skin from UV rays
The depletion of the ozone layer has increased the risk of skin damages from ultraviolet radiation. Thanks to sunscreen, you can block the rays from penetrating into your skin.
It reduces the risk of skin cancer
UV rays cause skin cancer when absorbed into the skin. Applying sunscreen every day before you step into the sun considerably reduces your risk of contracting skin cancer.
It prevents premature skin aging
Excessive exposure to the sun can damage the collagen and connective tissues of your skin, making your skin lose its elasticity and develop wrinkles which lead to premature aging of the skin. Wearing sunscreen reduces the rate at which your skin is exposed to the sun, invariably helping to prevent premature aging.
It helps to maintain an even skin tone
Sunscreen helps prevent skin discoloration and dark spots from sun damage, helping you maintain a smoother and even skin tone.
It reduces inflammation of the skin
UV rays sometimes cause painful redness and inflammation, wearing sunscreen every day helps to prevent inflammation from harmful rays.
Apply sunscreen approximately 30 minutes before going out – so that it can be absorbed by the skin and less likely to wash off when you sweat – for the best result.
