Powder sunscreen is usually really useful as possibility for touching up your safety all through the day. Should you’re sporting make-up, there is no approach you are going to redo your face each two hours simply to re-up with a liquid sunscreen, so powder SPF is actually the one sensible possibility. However, in line with beauty chemist Michelle Wong, PhD, these merchandise do not present practically as a lot safety as you could suppose. The explanation? The quantity of powder you’d want to use to truly get the quantity of SPF listed on the bottle is unattainable to use.
“You must cowl your pores and skin in sufficient UV-absorbing particles or molecules, in any other case an excessive amount of UV can get by the gaps to your pores and skin and trigger injury,” says Dr. Wong. “The SPF of a product is examined utilizing 2 milligrams per sq. centimeter utilized very evenly to pores and skin. Should you apply much less, you typically find yourself with decrease safety and it is a linear relationship—for instance, if you happen to apply half the quantity, you find yourself with half the SPF. Powder would not keep on with pores and skin very effectively, so it’s totally troublesome to use the correct quantity.”
In different phrases, if you happen to’re making use of an SPF 30 powder, at greatest, you are getting SPF 15 safety. Realistically, although, it is in all probability even lower than that.
“Because pores and skin is uneven, if you happen to apply lower than half the really useful quantity, you often find yourself with quite a bit much less safety since it will be patchy and you find yourself with loads of uncovered ‘hills’ in your pores and skin,” says Dr. Wong. “This can be a massive downside with powder, because it tends to use extra inconsistently than different product varieties like lotions and sprays.”
At the moment, the Meals and Drug Administration (FDA) does not recognize powder SPFs as a certified type of safety. As a substitute, the company recommends sunscreen in varieties like lotions, sticks, butters, and gels. “The upcoming FDA monograph excludes powder sunscreens, though Colorescience submitted knowledge on their powder sunscreen to the FDA for consideration,” says Dr. Wong.
Elizabeth Kream, MD, a dermatologist and incoming fellow on the Laser and Skin Surgery Center of New York, says powder sunscreen should not be your sole type of safety. Begin your routine with a liquid sunscreen and do your greatest to the touch up with a powder sunscreen each two hours (as a result of, sure—a touch-up with a powder is healthier than no touch-up in any respect).
“With powders, a draw back is that it is troublesome to quantify precisely how a lot you utilized,” says Dr. Kream. “Goal for 2 passes, transferring the comb in small circles, for a complete of about 60 seconds—ensuring that powder is definitely allotting out of the container and on the comb bristles. I prefer to flick the comb earlier than making use of to make sure this.”
Plus, keep in mind that SPF is not the one type of solar safety. “Searching for shade, sporting a hat or sun shades, limiting publicity throughout peak solar hours, and sporting layers,” can also be useful, says Dr. Kream. Be sure you observe the following tips frequently, however particularly on days when powder sunscreen is your solely type of SPF reapplication.
Dr. Kream recommends choosing a powder sunscreen with a better SPF. You continue to will not be getting the total SPF on the label, however getting a part of SPF 50 is much better than getting a part of SPF 30.
