This is not a drill. If you found out that one of the most versatile and
effective anti-aging formulas out there was something already sitting
in your bathroom cabinet, you probably wouldn’t believe it. And
who could blame you? But a new study in the journal
Dermatologic Surgery shows that sunscreen—yes, sunscreen—can not only protect your
skin but also reverse common signs of photoaging, like wrinkles and hyperpigmentation.
We know you're probably all like, " Sunscreen, really?" This
is like finding out that your nice, totally dependable, but otherwise
very boring colleague happens to be a vigilante superhero in her spare
time. The study, sponsored by the Johnson & Johnson's Skin Research
Center and led by dermatologists Steven Wang and James Leyden, showed
improvements in the many signs of aging caused by the sun, such as texture,
overall tone, and fine lines. With just a daily application of moisturizer
with SPF 30, participants saw improvements of 52 percent in mottled pigmentation
(a.k.a. sun spots), 40 percent in skin texture, and 41 percent in skin
clarity after a year of use.
This is huge, in part because the daily moisturizer in question provided
only hydration and sun protection—and zero anti-aging ingredients.
How, exactly, such a straightforward formula (compared to other, active-ingredient-packed
anti-agers out there) can give these results is still unclear, but Wang
has his guesses. “The most plausible answer has to do with skin’s
innate regenerative properties,” he explains. “We know that
skin turns over every 28 days. By preventing the continual accumulation
of more and more damage, we allow the skin to heal on its own.”
The sunscreen gives your skin a chance to indulge in some R&R instead
of constantly defending itself from UV exposure and repairing damage.
