Solar Radiation UVA/UVB/UVC

Radiation is a form of energy. Different types of bands are present in the radiation which defines the strength of the radiation. Solar radiation can be divided as Infrared, visible and ultraviolet radiation. Ultra-Violet (UV) radiation is further divided into UVA, UVB, and UVC rays.

UVA Rays – It stands for Ultraviolet A which is in the wavelength range 320 to 400 nm.- It causes the release of existing melanin from the melanocytes to combine with oxygen (oxidize) to create the actual tan color in the skin. It penetrates the skin more deeply as compared to the UVB, has long been known to play a major part in skin damaging & photo-aging.

UVB Rays – It stands for Ultraviolet B which is the chief cause of skin reddening and sunburn. It plays a key role in the development of skin cancer and a contributory role in tanning and photo aging also. Its intensity varies by season, location, and time of day. UVB rays are the common cause of most skin cancers.

UVC Rays – It stands for Ultraviolet C which is the most strongest and deadly of solar rays, however the ozone layer stops these harmful rays from reaching the earth surface.

The SPF Scoop

SPF stands for sun protection factor. Sunscreens are classified by an SPF number which refers to their ability to deflect UVB rays. The SPF rating is calculated by comparing the amount of time needed to burn sunscreen-protected skin vs. unprotected skin.

Use a broad spectrum SPF of 15 or higher to protect not only against sunburn, but reduce the risk of skin cancer and premature skin aging caused by the sun.
