It’s important to remember that while higher SPFs offer more protection, they don’t last any longer than lower numbers, so you need to reapply them just as often. A sunscreen with an SPF of 30, when used as directed, prevents 97% of UVB rays from reaching your skin. Sun protection factor (SPF) measures how much solar energy is required to cause a sunburn when you’re wearing sunscreen compared with unprotected skin. Plus, the stick makes for easy reapplying on the go. Thinkbaby SPF 30 Stick covers the basics without the glue-like feeling. To recap: “SPF 30 is the minimum I recommend, but higher is always better,” says Frey. ![]() But that extra protection is worth it for a beach day, even if you don’t want to opt for it daily. At a minimum, you’ll want SPF 30.įrey adds that higher SPFs tend to be stickier, so some people don’t like them as much. Recent research shows that SPF 100, when compared with SPF 50, makes a real difference in protecting your skin against damage and burns. New York dermatologist Fayne Frey reminds us that “no sunscreen is 100% effective at preventing burning and skin damage.” She also notes that sunscreen “can increase the amount of time you can be outside.”Īnd the amount of time spent outside is somewhat correlated to SPF. "Powder sunscreens may wash off easier, as they lack certain ingredients that adhere to skin and make lotion or spray formulas water-resistant," Aral explains.1. ![]() Once absrobed, follow up your cream or liquid sunscreens with powder.Īs for water-resistance, some powder SPFs are water-resistant, but each product is different so make sure you check the label before diving in. "They complement liquid sunscreens nicely," she says and. Garshick agrees that powder sunscreens are not meant to be used as the only sunscreen to protect the skin, but thinks that they offer a great extra layer of protection. "It's harder to form such protective films on skin using only powder ingredients, and they could be limited to lower SPF numbers or not provide a broad-spectrum protection."ĭr. "The efficacy of sunscreen comes from the robust films they form on skin which shield or absorb the harmful sun rays," says Aral. Yes, but not as your only form of sunscreen. "At the Good Housekeeping Institute, we are particularly interested in what the FDA’s ruling would be regarding the particle size allowed in these types of sunscreens as there is concern that inhaled nano-sized particles can be detrimental to health." Garshick considers them safe based on their active ingredients which "exist naturally as powders," she explains.īut Aral adds a caveat: "As per the FDA’s new proposed rule on sunscreens, more information and data is needed on powder sunscreens before they can be included," she says. While there isn't a ton of research on this newer sunscreen formula, Dr. "Under the FDA’s guidelines, all sunscreens are considered drugs and need to undergo efficacy testing," explains Good Housekeeping Institute Beauty Lab Director Birnur Aral, Ph.D. Yes, as long as the product has proper drug fact labeling. Here's what else you need to know before you swipe on powder sunscreen: "Plus, some powders have a mattifying effect, which is great for oily skin." If you have melasma, look for one made with iron oxides for additional protection against blue light, which can contribute to hyperpigmentation. "Most powdered formulations are comprised of titanium dioxide, zinc oxide, or both, which are typically good options for those with sensitive skin," Dr. They may not be as practical for the whole body based on the amount you would need to apply to ensure appropriate coverage. ![]() Powder SPF can be used anywhere, but according to Marisa Garshick, M.D., a dermatologist at MDCS Dermatology in New York City, it's best used as a touch-up for the face, neck, chest, and hands, which are areas prone to daily UV exposure, and for hard-to reach-or often-forgotten areas like the hairline and scalp. Sunscreen in a powder form? Yes, you read that right: Though SPF most often comes in creamy lotions, sheer sprays, or good ol' white zinc oxide, now sunscreen and powder have officially joined forces to give you mess-free protection, shine control, and sometimes, a little coverage, too. Until they reach a more robust conclusion in late 2020, the FDA advises, “Americans should continue to use sunscreen with other sun protective measures as this important rule-making effort moves forward.” Our GH Beauty Lab experts agree, and test a range of formulas (both mineral and chemical) that protect against sunburn. An important note on sunscreen safety: The FDA is currently proposing big changes to sunscreen regulations, and only physical sunscreens with the active ingredients zinc oxide or titanium dioxide are currently recognized as safe.
