What to Look For When Buying Sunscreen

Many people buy into the false assumption that sunscreen with higher SPF or sun protection factor means they could spend extra hours in the sun. This is a very common mistake. A sunscreen with an SPF of 15 blocks about 93 percent of the ultra violet rays and an SPF of 30 blocks about 97 percent of UV rays. However, any sunscreen with an SPF of 30 or higher remains in the 97 or 98 percent range of protection.


When buying sunscreen, it is not necessary to buy one with a high rating of SPF. What’s important is to look for sunscreens that protects against both UVA and UVB radiation. For so long now sunscreen has successfully blocked UVB rays. The SPF ratings only apply to UVB rays. Yet, UVA rays are as important as UVB. It penetrates the skin more deeply and has long been a major affect for skin wrinkles.


One thing to put in consideration when applying sunscreen is to carefully follow the label. Many people apply sunscreen without carefully examine the amount necessary for maximum protection. In result, if you’re placing less than the amount indicated, your skin will not be fully protected.


Another thing to remember is always apply sunscreen on 15 minutes before going out in the sun and reapply every two hours.
