Sunscreens and sun blocks are lotions containing one or more protective chemicals that absorb, reflect or scatter ultraviolet rays. Sun Protection Factor (SPF) indicates the specific amount of protection that is provided by a particular sunscreen product. An SPF of 15 indicates that it will protect you 15 times longer than when you stay in the sun without the sunscreen
Sunscreens are recommended for most outdoor activities. They are available in many forms such as lotions, gels or sprays and lip balms with a variety of SPF. Here is some tips on purchasing sunscreen and when and how to use sunscreen.

Look for a preparation with broad spectrum Ultraviolet A and B protection. Preparations that contain reflective substances such as titanium dioxide and zinc oxide provide the most effective protection.
A”sun protection factor” (SPF) of 15 or more. The higher the number, the better protection.
