New Advance in Sunscreen: Better UVA Protection
| A new FDA-approved line of sunscreens now protects against intense and harmful ultraviolet A, or UVA, radiation, which scientists have linked to wrinkles, basal and squamous cell cancers, and melanoma. An ingredient called encamsule works to screen out the UVA rays. Previously available broad-spectrum sunscreens protect against UVB radiation as measured by the SPF number, but have less effective UVA protection.
"UVA light penetrates deeper into the skin and is more damaging than UVB light," says Allison Vidimos, RPh, M.D., Chair of The Cleveland Clinic’s Department of Dermatology. "The improved protection this product offers causes less biochemical change in your skin." Both UVA and UVB coverage are vital in protecting the skin against sunburn, skin cancer and premature aging, Cleveland Clinic dermatologists say. This is the first time encamsule has been marketed in the United States; it has been available in Europe and Canada since the 1990s. Another new sunscreen is Helioplex . This broad spectrum sunscreen effectively screens both UVA and UVB rays and is stable in sunlight. |

Most importantly, Dr. Vidimos stresses using enough sunscreen to obtain the necessary protection. Sun-seekers must use the correct amount for best results.
"Most people make a bottle of sunscreen last all summer," she says. "If that’s the case, they are simply not applying an adequate amount each time they go into the sun." She explains you should use a full shot glass of sunscreen - equaling one ounce - to cover your exposed skin every couple of hours, including a full teaspoon for your face and neck.
"The majority of the population uses only about half the required amount," Dr. Vidimos explains. Apply the sunscreen 30 minutes before going out into the sun, and then reapply every two hours. That means a six-ounce bottle may only last a couple days, indicating another purchase in the near future.
"A good sunscreen may cost a few dollars more," she says, "but the expense is worth it. It’s definitely an investment in your health and well-being for the future."
According to Cleveland Clinic dermatologists, fair-skinned folks should use an SPF of at least 30, and ideally apply it every day. The rule of thumb is the lighter the skin type, the higher the SPF number.
