Using Sunscreens Wisely

The choice of which sunscreen you use and how you use it are critical for the protection of you skin. Sunblocks and sunscreens offer ultraviolet light protection by two means: absorption of ultraviolet light, and reflecting and scattering ultraviolet light. Ultraviolet light (UVA) exposure causes damages to your skin cells, which can cause skin cancer. Even with regular use of sunscreen, it is a good idea to check yourself regularly for skin abnormalities,http://www.dermatologychannel.net/skincancer/melanoma/symptoms.shtml and to use other means of protecting yourself from the sun. People with different levels of melanin in their skin require different amounts of sunscreen to protect them from the sun. This page gives you recommendations on sunscreen choices and uses so you can be a smart consumer.
How to Choose a Sunscreen - A Sunscreen Buying Guide

As you move up in the SPF ratings past an SPF of 15 you don't get much more protection. For instance, the protection ratings of SPF 15, 30 and 40 are 92%, 97% and 97.5%. http://www.gosunsmart.org/yourskin/yourskin_protection.shtml Also, don't choose a suncreen solely based on its SPF rating, which only rates UV-B rays, not skin damaging UV-A rays. Rather, it is better to look for products that advertise "broad-spectrum protection," which means it protects against both types of rays. Broad-spectrum sunscreens have avobenzone or sun-blocking minerals such as titanium dioxide or zinc oxide. These minerals are considered the best for protection against sunburn. http://www.makeupandbeautyblog.com/skin-care/what-to-look-for-when-buying-a-product-with-spf/
