It is extremely important to protect our skin from harmful UV rays, and applying face sunscreen is an excellent way to do so. According to dermatologists, you should apply face sunscreen every morning, and reapply every two hours if you are in direct sun exposure. It is crucial to use a sunscreen with an SPF (sun protection factor) of at least 30, and one that is labeled as “broad-spectrum” to protect from both UVA and UVB rays.
According to the Skin Cancer Foundation, “Sun damage is cumulative and irreversible, so it is important to protect your skin from the get-go.” This means that applying sunscreen every day can greatly reduce your risk of developing skin cancer, or other skin-related issues such as wrinkles, dark spots, and sagging skin.
Furthermore, it is important to apply sunscreen even on cloudy or overcast days, as UV rays can still penetrate through clouds and harm your skin. If you are engaging in water-based activities or sweating, it is essential to reapply sunscreen more frequently.
In order to ensure that you are applying the correct amount of sunscreen, the American Academy of Dermatology (AAD) recommends using the “2 finger rule.” It is suggested that you apply sunscreen in a line on your index and middle fingers, and then use those fingers to apply to your face. This method ensures that you are applying enough sunscreen to your face, neck, and ears.
To make it easy for you, here is a table summarizing the key points mentioned above:
| Apply face sunscreen every morning | Reapply every 2 hours in direct sun exposure |
| Use an SPF of at least 30 | Use a sunscreen labeled as “broad-spectrum” |
| Apply even on cloudy or overcast days | Reapply more frequently when sweating or in water |
| Use the “2 finger rule” to apply enough sunscreen |
As acclaimed dermatologist Dr. Howard Murad says, “Sunscreen is key to maintaining healthy, youthful looking skin… Sunscreen should be something you reach for every day, just like brushing your teeth or combing your hair.” So don’t skimp on the sunscreen – your skin will thank you in the long run!
Dr. Dray provides advice on how much sunscreen to apply and how often it should be reapplied. She suggests using anywhere from a third to a full teaspoon of sunscreen, although she emphasizes spending more time putting on the sunscreen to cover all areas of the body. She recommends reapplying the sunscreen every two hours when outdoors and every three times a day when indoors to ensure maximum protection, even on low UV index days. Dr. Dray answers common questions about sunscreen application, advising against washing off the sunscreen or using blotting papers to remove the shininess of the sunscreen, and recommends using a mineral sunscreen powder to mattify the shininess and reapplying without washing the face in between. She stresses the importance of washing it off at the end of the day with an oil-based cleanser for water-resistant sunscreens to avoid acne flare-ups and reassures people that there’s no need to worry about sandwiching dirt and bacteria with sunscreen applications.
Other methods of responding to your inquiry
Generally, sunscreen should be reapplied every two hours, especially after swimming or sweating. If you work indoors and sit away from windows, you may not need a second application. Be mindful of how often you step outside, though.

SPF50 should protect you 50 times as long as your skin would be able to naturally protect itself. However, remember that the lower the SPF and longer the length of time since application, the less UVB rays will be filtered, so a reapplication every two hours is highly recommended.
So, how long does sunblock* last on skin? Usually, you can rely on your sunscreen for protection for up to two hours. However, your sunscreen will only last about 40 to 80 minutes with water (or sweat) exposure.
