Sunscreen protects our screen from the sun's ultraviolet radiation(UV).
The sun's UV rays are of two types: Ultra Violet A(UVA) is of a longer wavelength and can penetrate the skin down to the middle layer. Ultra Violet B (UVB) is of a shorter wavelength and can penetrate the skin to the top layer.
Sunscreen could be in the form of a lotion, cream or spray.
Long periods of sun exposure gradually damage your skin whether it is visible through sunburns or not.
It is important to note that even on cloudy or cold days the sun rays can still penetrate through the skin.
The Skin Cancer Foundation, a New York non-profit organisation, said that everyone including men, women and children will experience the following benefits when using sunscreens;
It helps prevent premature skin ageing, decreases the risk of skin cancers and skin pre-cancers and prevents the skin from sunburn.
Long periods under the sun could result in hyperpigmentation meaning that the exposed parts could darken in an inconsistent way. Sunscreen could prevent this from happening.
