There are a lot of misconceptions that people have in the proper application of sunscreen lotions. The proper use of sunscreens is essential to avoiding sunburns, skin cancer and premature skin aging. Skin cancer is the most common type of cancer, and malignant melanoma is a skin cancer that is one of the most deadly of all cancers. Proper application of sunscreen can help prevent serious trauma to your skin and may even save your life.

Important things to know about sunscreen application

• Apply sunscreen even on cloudy days—UV rays affect your skin wherever it is exposed, even when it’s cloudy. Daily application and donning other protective measures like hats, sunglasses and protective clothing are equally important.
• Reapply every few hours for the best protection—Sunscreen loses its power over time, so it’s best to reapply every 2-4 hours. This depends on how long you are in the sun and if you are sweating excessively or swimming, since the lotion will wear off and need reapplication more frequently.
• Barrier and absorption sunscreens—Chemical sunscreens are absorbed into the skin and physical sunscreens create a protective barrier. Sunscreens that contain titanium or zinc oxide are the physical barrier type and are recommended for those individuals who have sensitive skin.
• 50 SPF (sun protection factor) is all you’ll ever need—Sunscreens that go beyond an SPF of 50 offer very little difference in effectiveness and protection. In fact, 40 SPF is fine for many people unless you have very fair skin.

Damage to your skin accumulates and can manifest years later, so it is important to protect your skin through daily sunscreen use. If you notice any abnormalities in your skin, consult with a board-certified dermatologist.
