The Anti-Aging Benefits of Sunscreen
When it comes to reversing the clock, Botox is one of the best routes to take. However, preventative skincare for anti-aging is just as important. The way sunscreen protects your skin from the sun is by filtering out harmful ultraviolet radiation. Sunscreen is one of the go-to’s for preventative aging. Sunscreen protects your skin from three types of damage from the sun’s rays which consist of sunburn, skin cancer, and premature aging. Whether sunscreen can help avoid wrinkles, age spots, and other symptoms of premature skin aging depends on which type of ultraviolet radiation they block. There are three different types of ultraviolet radiation: UVA, UVB, and UVC. UVA and UVB both contribute to skin damage, UVA rays are now known to cause premature skin aging which results in wrinkles, changes in skin texture, and uneven pigmentation. UVB is the one that is the culprit for skin burning.
There was an Australian study that was conducted which found that those who applied sunscreen everyday during the 4.5-year study experienced 24 percent less skin aging. To avoid premature aging of your skin, it is best recommended to use a sunscreen identified as “broad-spectrum” which means that it protects your skin from both UVA and UVB rays. Most sunscreens only protect from UVB which causes burning. Since 2012, the FDA has requested that all sunscreen manufacturers indicate whether their product offers broad-spectrum protection. When it comes to SPF level, the American Academy of Dermatology recommends a sunscreen with an SPF of at least 30. Also, sunscreens containing zinc oxide and titanium dioxide protect against both UVA and UVB rays. Whichever broad-spectrum sunscreen product you choose, you should apply at least two fingers worth to your face. If you end up doing rigorous activities, then you should reapply it after swimming or working out. It is also recommended to avoid the sun during peak UV exposure hours.
