Speaking of sunscreen spray, it is a must for many people when going out for fun. This sunscreen spray can protect your skin. Let’s see how often you should spray the sunscreen spray? When to use sunscreen spray:

How often should you apply sunscreen spray?

1. When outdoors, you need to reapply sunscreen spray every 2 hours

If you stay outdoors all the time, it is best to reapply sunscreen spray every 2 hours. Because most of the sunscreens in sunscreen sprays are chemical sunscreens, they will gradually lose their sunscreen effect after absorbing ultraviolet rays. So if you are outdoors for a long time, please reapply every 2 hours.

2. Reapply sunscreen spray once every 1 hour when you are outdoors and sweating

If you are outdoors all the time and sweating, we recommend that you reapply sunscreen spray once an hour. Because sunscreen spray will be diluted by your sweat, thereby reducing or even losing its sun protection effect.

3. Apply sunscreen spray immediately after entering the water

The shelf life of sunscreen sprays is usually indicated on the spray, which is usually around 60-80 minutes. But if you go into the water, no matter how long the sunscreen spray is advertised to be waterproof, you should reapply it immediately.

4. Reapply sunscreen spray in water according to the waterproof time

If you are always in a water environment, we recommend that you reapply the sunscreen spray according to the sun protection time advertised on it. For example, the advertised waterproof time on sunscreen spray is 60 minutes. Then we should reapply sunscreen spray every 60 minutes in the water.

5. Reapply sunscreen spray every 2 hours when sitting near a window indoors

Don't think you can skip sunscreen spray when you're indoors. If you sit near a window, you are almost outdoors. Even if there is a window, ultraviolet rays can still penetrate the glass and burn your skin. Therefore, if you are indoors near a window, it is recommended to reapply sunscreen every 2 hours.

6. If you are not near a window, reapply sunscreen spray at noon or after get off work.

If you are indoors without a window and without direct sunlight, we recommend reapplying sunscreen spray at noon. If you really want to be lazy, it is necessary to at least reapply sunscreen spray before leaving get off work. Don't think that sunscreen spray will only become ineffective when exposed to ultraviolet rays. Over time, the oil and sweat secreted by our faces, as well as some face-wiping habits, will reduce the sunscreen effectiveness of our sunscreen spray.

When to use sunscreen spray

Sunscreen spray should be used about 15 to 30 minutes before going out in the morning. Use sunscreen spray as the last step in your skin care regimen. After cleansing in the morning, use toner to condition your face, then moisturize with lotion, and finally use a sunscreen spray. After spraying, wait for about 15 minutes until the sunscreen forms a film before going out.

This is all about the time and frequency of spraying sunscreen spray. It is better to take good care of your own skin.
