Remember the days of unlimited tanning bed passes? Or slathering on coconut oil before basking in the sun? We’ve come a long way in protecting our skin from the elements. Going without a layer of SPF seems criminal today, yet even now that the practice has become second nature for so many of us, we still can’t seem to avoid the long-term effects of sun exposure.
The unfortunate truth is, we begin accumulating sun damage from the day we’re born. “People often say, ‘I was born with these freckles,’” says Washington, D.C. dermatologist Tina Alster, MD. “However, no one is actually born with freckles. They appear when the skin is exposed to the sun. So, while people may recall having them, that’s only because they went outside when they were young. Regrettably, children are not as protected from the sun as dermatologists want them to be.”
Recent studies have shown that sun damage can happen in less than an hour. Even when we’re cautious to avoid sunburns, the cumulative effects of the sun’s harmful rays can last for what seems like eternity. However, all is not lost, and our experts say there are a number of effective ways to hit the reset button on aging skin.
What Sun Exposure Does
There are three different types of ultraviolet rays: UVA, UVB and UVC. UVA rays penetrate skin to its deepest layers, into the dermis, and damage the cells which leads to premature aging. UVB rays have a shorter wavelength and don’t get past the epidermis; they’re largely responsible for sunburns. Both types can play a role in the formation of skin cancer. UVC rays are the most harmful, but the ozone layer blocks us from them.
“Sun damage is associated with UV radiation and causes damage to the skin called photoaging,” explains Eagan, MN dermatologist Charles Crutchfield III, MD. “Some of the typical changes that occur include brown spots, uneven tone and texture, thinning of the skin, and wrinkling.”
“Those with fairer skin are most at risk,” says Denver dermatologist Joel Cohen, MD. “The reason is that melanin helps attenuate UV rays. This doesn’t mean if you have melanin-rich skin you aren’t at risk. There are a lot of misconceptions about skin cancer and sun-protection, and everyone should be wearing sunscreen with the right ingredients like zinc.”
