Using this method, you can work out that higher SPF ratings don’t actually give you much more protection than medium SPF ratings. The Skin Cancer Foundation reports that SPF 15 blocks 93% of UVB rays, SPF 30 blocks 97% and SPF 50 blocks 98%. While these differences seem insignificant, they can still make a great difference over time, especially if you have fair skin or a history of cancer.
Although jade and rose quartz rollers have played a key role in Chinese beauty regimens for centuries, they only recently became a staple in American vanities. Using the smaller stone, gently roll it underneath your eyes in outward motions to promote blood flow and soothe puffy skin. Pro tip: Throw your roller into your refrigerator before each use for the ultimate cooling experience.

Facial primer is also a key player in the fight against dark circles. Color-correcting primers with a yellow tint are going to be your new best friend. A yellow primer can neutralize dark, bluish under-eye circles, and because the primer is so sheer, it's easy to blend, explains makeup artist Joanna Schlip. She recommends dabbing a teeny bit over dark circles (try Make Up For Ever HD Microperfecting Primer in Yellow), and then spreading your foundation on top. "If your circles are very dark, you can tap regular concealer over the primer, and then layer on your foundation," she says. Bonus: Because primer contains silicone to fill in wrinkles, it'll also prevent makeup from creasing in smile lines.
Vitamin A and its derivatives (retinoids) are the most prevalent anti-aging ingredients on the market today. Tretinoin, a retinoid approved by the Food and Drug Administration (FDA), is only available by prescription. And although there is ample scientific evidence that shows the ability of retinoids to have a positive effect on cell gene rearrangements, fibroblast activity, and collagen synthesis, studies proving cosmetic benefits with statistical significance are lacking.
Protect your skin from the sun. Exposure to UV light speeds up the natural aging process of your skin, causing wrinkles and rough, blotchy skin. In fact, sun exposure is the No. 1 reason for signs of aging in the skin, including uneven pigmentation. Protect your skin — and prevent future wrinkles — by limiting the time you spend in the sun and always wearing protective clothing and a hat. Also, use sunscreen on exposed skin year-round when outdoors.
