Can my sunscreen be anti-aging?
It turns out sunscreen does more than protect you from cancer and painful sunburns — it offers a boost to simple vanity.
A new study found that regular sunscreen use protects against photo aging: the wrinkling, spotting and loss of elasticity caused by exposure to the sun’s ultraviolet radiation.
While they may not be shocking, the findings — from Australian researchers — are the first to quantify sunscreen’s anti-aging properties.
More than 900 participants were followed for four years. Some were told to use sunscreen daily and instructed in proper use, including re- applying sunscreen after being outside for a few hours, after going in the water or after sweating heavily.
Other participants were given no directions with regard to using sunscreen — it was considered unethical to ask them to not use it.
Skin changes were measured through a technique called micro topography, in which researchers made sensitive silicone impressions of the back of each participant’s hand.
Damage was measured on a scale from 1 to 6, with 1 signifying no damage and 6 meaning skin with severe aging. Participants were given a score at the start of a four-year period and another score at the end; those who used sunscreen daily were 24% less likely to show increased signs of aging, researchers found.
“We now have the scientific evidence to back the long-held assumption about the cosmetic value of sunscreen,” says an Australian researcher. “Regular sunscreen use by young and mid-aged adults under 55 brings cosmetic benefits and also decreases the risk of skin cancer.”
The FDA’s sunscreen requirements ease the challenge by making labels less misleading and products more effective. Under these rules, sun care companies must test products for “broad-spectrum” coverage, which means protection from once-ignored UVA rays (those linked to skin cancer) in addition to UVB (responsible for burns). Sunscreens also have to quantify “water-resistant” claims and eliminate labels touting SPFs of 50 or higher (after 50, additional protection is miniscule).
Am I getting enough UVA protection?
When you get burned, UVB rays are the culprits. A sunscreen’s SPF, which stands for Sun Protection Factor, measures protection from UVB rays only, not UVA rays, which make up about 95 percent of those that reach Earth and are actually more detrimental to long-term health.
Responsible for a seemingly harmless tan, UVA rays penetrate the skin more deeply and generate free radicals in your skin, leading to wrinkling and skin cancer over time. The most effective ingredient for UVA protection is zinc oxide, although products frequently include the chemical avobenzone for UVA protection, it absorbs rays rather than reflecting and scattering them. Avobenzone also is unstable, so it may break down into unknown chemicals.
