WHAT TYPE OF SUNSCREENS WORK BEST AND HOW SHOULD THEY BE USED?
Sunscreens are available in a wide variety of different products. It is recommended that you select a product with a sun protection factor (SPF) of at least 15. This number correlates to the degree of blockage. An SPF of 15, for instance, allows you to stay in the sun 15 times longer than normal without burning. Although products are available with an SPF of 30 or 45, there is serious debate over how much added protection you really are receiving. Select sunscreen products that block against UVB and UVA rays, since both are believed to induce skin cancer. The SPF rating however applies only to UVB rays. There is no way at present to gauge how much protection from UVA rays a sunscreen will afford. Here are other tips for applying sunscreen: Apply sunscreen 15 to 30 minutes before going outside. You will need at least one ounce of the product to cover an average size body. If you are swimming or sweating be sure that you have a waterproof sunscreen and reapply more frequently. Sunscreens
