Sunscreen has been round for nearly 100 years, so it is about time issues obtained fascinating. For higher or worse, the previous few years have seen modern sun-protection methods hit the market — some we love, like SPF for the scalp, and a few that fear the Meals and Drug Administration, like alleged “sunscreen drugs.”
One seemingly new-school invention is powdered sunscreen, like the brand new Paula’s Alternative On-the-Go Shielding Powder SPF 30, Colorescience’s Sunforgettable Complete Safety Brush-On Defend SPF 50, and the Brush On Block Translucent Mineral Powder Sunscreen. However does a powder present the identical safety as slathering in your favourite lotion sunscreen? We requested the consultants how we ought to be working this new choice into our skin-care routines.
What’s powdered sunscreen?
I’ve at all times pictured the inventor of sunscreen merchandise to be a scientist with an awesome spray tan and large sun shades, working in a lab located straight on the equator. However in keeping with beauty chemist Stephen Alain Ko, powdered sunscreen is much from a brand new improvement. In truth, the lively elements in all sunscreens exist already in powder kind. “Titanium dioxide and zinc oxide used as sunscreens are already supplied as powders or powders dispersed in liquids,” says Ko.
Cream and spray sunscreens are formulated as liquid to “guarantee most dispersion of the titanium dioxide and supply a fair coating of sunscreen brokers on the pores and skin,” Ko says. There isn’t any “particular formulation” that turns sun-protective elements into powders as a result of they exist that manner within the first place. Ingredient-wise, you are getting the identical items in a tin of powder that you’re in a sprig can.
How do you have to apply powdered sunscreen?
The “shot glass rule,” for the unfamiliar, is a layman’s manner of creating positive that you simply put on the correct quantity of sunscreen. The rule states that it takes a couple of shot glass stuffed with cream or lotion sunscreen to adequately cowl the physique.
However the identical rule does not apply to powdered sunscreen. Ko’s weblog has a useful visible illustration of how a lot powder it takes to attain the SPF safety claimed on the label. In case your powdered sunscreen is labeled SPF 25, however you solely blot on a swipe of powder, you are doubtless not getting the total energy of the sun-blocking elements.
“It quantities to fairly a considerable amount of powder, which most individuals might not have a simple time making use of,” says Ko. He factors out that Colorescience recommends “two passes” when making use of its powdered sunscreen.
When do you have to use powdered sunscreen?
“In principle, powdered sunscreens could be nice if totally utilized to your complete face in a thicker coat,” says Anna Guanche, a California-based board-certified dermatologist. However since nobody has the time (or cash) to use half a jar of powder to their faces midway via a seaside day, she recommends saving SPF powder for touch-ups.
“Apply a combined chemical and bodily sunscreen to the pores and skin very first thing within the A.M.,” says Guanche, “then contact up with the powder sunscreen all through the day on probably the most sunburn-prone areas: midface, nasal bridge, and higher brow.”
Shari Marchbein, board-certified dermatologist and medical assistant professor of dermatology at New York College Langone Well being, agrees that powder is nice, so long as you are not simply utilizing powder. “They are perfect for reapplication over make-up, however I might warning towards [using powder] as a main technique of solar safety, as the quantity utilized is probably going inadequate to correctly shield the pores and skin,” she says.
These dermatologists don’t recommend ditching powdered sunscreen altogether — in spite of everything, everybody can use extra solar safety. Simply make certain that you are including it to an current base of sunscreen-coated pores and skin, as an alternative of utilizing powder as the one barrier between your self and UV rays.
OK, I’ve all my sunscreen on. What now?
This would not be an article about sunscreen if we did not remind you that sunscreen is not the one strategy to shield your self from all of the skin-damaging results of UV rays. “Keep in mind to additionally put on hats, sun shades, and protecting clothes, together with lengthy sleeve shirts, to stay correctly protected,” says Marchbein. That is after you coat your face and physique in cream or lotion SPF — after which blot away any summer season sweat with an additional swipe of sunscreen powder.
