What is the best way to use sunscreen and what is the best sunscreen to use?

Sun protection is a major concern for the prevention of skin cancer, as well as lines and wrinkles. One of life's cruel ironies is that most people will receive 75 percent of their total lifetime sun exposure by age 21. In other words, by the time most of us are wise enough to protect ourselves from the sun; it's too late. The most effective sunscreens contain both an SPF (sun protection factor) of 15 or higher and UVA (ultraviolet A) protection. The SPF protects against burn, which is caused by UVB (ultraviolet B) rays. UVA rays actually penetrate much deeper and cause more long-term damage, such as skin cancer. To properly protect your skin, apply sunscreen 30 minutes before sun exposure (it takes 20 minutes for the lotion to set in the skin) and reapply every hour. Of course, it should be applied even more frequently if you are perspiring or swimming. Melashade is a great, new sunscreen that is designed specifically for the face.

The second component is sun-protective clothing. The key here is to make sure that the fabric has an extremely tight weave that blocks out the sun's harmful ray, yet is lightweight and vented for comfort. Coolibar produces an extensive line of sun-protective clothing and accessories for adults and children.
