How Much Sunscreen Is Really Necessary for Daily Use?. You probably assume that a sunscreen that has an SPF of 30 on the label will protect you from UVA rays. It will, under certain conditions. Any mineral or chemical sunscreen with a higher sun protection factor has everything you need to protect your skin from the sun. Nevertheless, the effectiveness of your skin’s defense against sun damage ultimately depends on how much of your selected formula you apply and remember to reapply. And very few of us are truly applying enough every single day, if we are being totally honest with ourselves.
You would have to duplicate the application that is done in the lab. Which is two milligrams per square centimeter for the average person. In order to get the protection labeled on the product. “Really, people use somewhere around half of that amount,” explains board-certified dermatologist Ranella Hirsch. “That translates to half a teaspoon on face and neck combined — a quarter teaspoon each — and 1 teaspoon per arm and leg each, front and back.”

How much sunscreen ought to be on your skin?
Marisa Garshick and other board-certified dermatologists we consulted all agreed that the recommended amount of sunscreen to achieve the SPF listed on a bottle is two milligrams per square centimeter of skin. “Which is equivalent to one shot glass for the body or two tablespoons,” as Garshick explains. “For the face, it is recommended to apply a nickel-sized dollop — the equivalent of two finger lengths. Which is also equivalent to half a teaspoon, to the face and neck combined.”
She notes that regardless of whether the formula is chemical or mineral, where you live, or the season. It is crucial to apply this amount as it is required to offer the level of protection listed on the bottle.
For sunscreens that you might find difficult to gauge how much to use by squeezing globs onto your fingers or into a shot glass. You’ll need to use different methods to be sure you’re putting on enough. “For stick sunscreens, it’s best to apply four passes back and forth and then rub it in after for even coverage,” explains Garshick. Cetaphil Sheer Mineral Sunscreen Stick Broad Spectrum SPF 50 is one of our top picks. She also suggests treating the skin with sunscreen mists and sprays till it shines. “I always tell patients, ‘If it’s glistening, then you’re listening.'” We are huge Supergoop lovers!
