Sunscreens are one of the most use skin care product of this century. Sunscreens contain SPF (sun protecting factor) that forms a protective layer on the surface to radiate back the UV rays coming from the sun. UV rays are dangerous electromagnetic rays and exposure to them cause problems as severe as skin cancer. SPF is the measure of the amount of time the sunscreen will protect the skin from the sun. When choosing a sunscreen for yourself, it’s important to always check for the SPF number. Sunscreens are selected by both, the time of your sun exposure and your age. After the discovery of ozone layer depletion, skin cancer and sun burn issues started being reported on a daily basis. After this, people realized skin protection products would be needed to prevent problems caused by the sun rays. Sunscreens were introduced and are since being widely produced to meet the demands of consumers all around the around. eWorldtrade has gathered a list of the most renown companies that manufacture the best quality of sunscreens.
