UV Rays, Sunblock and You!
Filed under: Beauty

There are three kinds of invisible ultraviolet (UV) rays in the sun that reach the earth: UVA, UVB and UVC.UVC
UVC does not reach us as it is absorbed by the upper levels of the atmosphere.
UVA
UVA is the most dangerous as it penetrates deep into the skin. It degrades the elastic fibers in the skin, causes skin aging and darkening.
UVB
UVB penetrates the top layers of the skin, resulting in sunburn and the formation of wrinkles, dark spots and freckles.
Daily exposure to UVA and UVB rays has a cumulative effect on our skin. The more our skin is exposed to the sun, the higher the risk of potential skin damage.
What Is SPF?
SPF stands for Sun Protection Factor. SPF is the rate of protection against UVB. PA is the measure of defense against UVA, with the highest rate being +++
Which SPF Rate Is Right For You?
SPF is an indicative number on sunscreen labels. It tells you the relative length of time that you can stay exposed to the sun before you get sunburnt. The higher the SPF number, the longer it protects a person from burning rays. For most people, SPF25 is generally sufficient for daily UV protection. However, if you are fair skinned or if you are planning to stay out under the sun for a long period, it’s advisable to get a product with a higher SPF.
