The cause of skin cancer is unrepaired damage to the DNA of skin cells. This damage can be caused by various factors with the major one being ultraviolet radiation. Sunscreen is a topical product designed to either reflect the ultraviolet rays of the sun or to prevent them from penetrating into the skin and damaging the DNA of the cells. Find out how to make the most out of sunscreen and take a note of its limitations so that you can adopt even more effective skin protection measures.

Sunscreen and Skin Cancer Prevention 

Researchers have found that the average person gets only between 10 and 25 per cent of the protective benefit of sunscreen due to incorrect application. It is important to follow some simple rules when applying such a product so that you can make the most out of it. Apply sunscreen every time you go out even on cloudy days. Make sure that the product has not expired. Shake the bottle well before use. These simple tricks should provide adequate protection from sunburn and severe consequences such as skin cancer. Apply sunscreen 20 to 30 minutes before going out. Cover every skin area that is not covered by clothing. Areas vulnerable to sunburn that most people miss include the T-section of the face, the ears, and the neck, the back of the legs, the hands and the feet. Use a lip balm with sun protection properties to protect your lips as well. Use a handful of sunscreen for your entire body and no less. Reapply the product every 2 hours for effective protection from sunburn and skin cancer. Do it even more often if you stay in the water or exercise and sweat.

Other Important Measures for Skin Cancer Prevention

Even a sun block with SPF over 30 blocks only about 97 per cent of the ultraviolet radiation. Doctors say that no product offers full protection from sunburn and from skin cancer. Furthermore, it is easy to forget about the rules for the correct use of sunscreen when you are on the beach enjoying all sorts of activities with friends and family. That is why it is important to know and to adopt other effective measures for protection. Avoid the mid-day sun. It is best not to expose yourself to direct sunlight from 11 in the morning to 5 in the afternoon. Stay in the shade as much as possible when you go out. Wear clothing with ultraviolet protection rating and a wide brim hat especially if you regularly spend a lot of time outdoors.
