How to Apply Sunscreen: Cream, Stick and Spray
Sunscreen comes in more than creams and lotions. There are sticks and sprays too, and each one goes on a little differently. It is easy to wonder how many swipes of a stick are enough, or whether a spray can go straight onto your face. This note puts together what the American Academy of Dermatology (AAD) tells the public about applying each type and reapplying it.
On hot, humid or rainy monsoon days, sweat makes reapplying the part people think about most. This is general information. Follow the directions on your product's label for how much to use and how often to reapply, and if your skin reacts, stop using the product and see a dermatologist.
Cream and lotion: the basics for every type
The AAD says to apply sunscreen before going outdoors. Its sunscreen FAQ puts it as applying to dry skin 15 minutes before you go out. The amount is more than many expect. According to the AAD, the face needs at least 1 teaspoon, about the length of your index and middle fingers. To cover skin not covered by clothing, most adults need at least about 1 ounce, roughly enough to fill a shot glass.
Then rub it thoroughly into your skin. The AAD reminds people not to miss the neck, ears and tops of the feet. Which type you use is a matter of personal choice, the AAD says. Whatever the type, the AAD's recommendation is the same: broad-spectrum (UVA and UVB) protection, SPF 30 or higher, and water resistance.
Sticks: four passes on each area
The AAD describes sticks as easy to use under the eyes and on the backs of the hands. Its instructions are specific. For each area of skin, apply four passes back and forth, then rub it in for an even layer. The AAD explains that the four passes help make sure you are using enough.
Sprays: not straight onto your face
Hold the nozzle close to your skin and spray generously. Because it is hard to tell how much spray is enough, the AAD suggests spraying until your skin glistens. Then rub it in so no spots are missed and the layer is even. The AAD also notes that a typical 6-ounce bottle of spray sunscreen holds six applications.
For your face, spray it into your hands first and apply from there. The AAD says not to inhale spray sunscreen and never to spray it around or near your face or mouth. It advises against using sprays on windy days, when they are harder to apply and easier to breathe in by accident. Because sunscreen in aerosol form can be flammable, the AAD also says never to spray it near heat or an open flame, or while smoking, and to make sure it is rubbed in and dry before going near a grill, candles or other fire.
Reapplying on hot, sweaty and cloudy days
The AAD says to reapply sunscreen every two hours when outdoors, and immediately after swimming or sweating. Its FAQ adds that you should do this according to the directions on the bottle. On a hot, humid day you may sweat well before two hours are up, so it helps to keep the second condition in mind too. Before reapplying, blot away sweat and oil with a clean tissue.
A water-resistant label does not mean you can skip reapplying. The AAD explains that while some sunscreens are water resistant, no sunscreen is waterproof or sweatproof. Water-resistant sunscreen should still be reapplied after swimming or sweating. The AAD adds that moisturisers and cosmetics with SPF also need reapplying approximately every two hours when you are outdoors.
Cloudy days count too. The AAD's FAQ says that even on cloudy days, up to 80% of the sun's harmful UV rays can penetrate the clouds, and that sunscreen should be reapplied approximately every two hours outdoors, cloudy or not. Windows are worth a thought as well. According to the AAD, UVA rays can pass through window glass, while UVB rays are blocked by it.
Sunscreen and the HANARI routine
HANARI does not make sunscreen. Our three daily products in preparation, Clean Start Gel Cleanser, Even Days Serum and Air-Fit Gel Cream, form a routine of cleanser, serum and moisturiser, and sunscreen comes after them as a separate morning step. The serum and gel cream do not replace sunscreen. The routine itself is laid out in A Three-Step Skincare Routine for Hot, Humid Days. The three products are planned to launch together in India in December 2026, and none of them is on sale yet.
