Do I need to wash my face when applying sunscreen? When should I apply sunscreen again?

Sunscreen has a great skin care effect. It can form a thin film on the skin to isolate ultraviolet rays. Before applying sunscreen, you need to apply other moisturizing skin care products. Sunscreen needs to be reapplied after a period of time.

You don’t need to wash your face when reapplying sunscreen, because sunscreen forms a thin film on the skin to block ultraviolet rays. If you apply sunscreen after washing your face, it is not reapplying sunscreen. Therefore, it is recommended that you reapply sunscreen directly without washing your face, whether you are wearing makeup or not.

1. Use tissue or cotton pad to wipe off excess oil and sweat on your face and limbs.

2. Apply sunscreen on your face and limbs.

3. Apply sunscreen and gently press and pat the skin.

Time to reapply sunscreen

The time to reapply sunscreen depends on the sunscreen you have. It is generally recommended that you start reapplying the first sunscreen three to four hours after going out, and then reapply every two to three hours. If you are indoors or when the ultraviolet rays are not strong, reapply every three to four hours. When doing outdoor sports or swimming at the beach, reapply every one to two hours.

Why should you reapply sunscreen?

After applying sunscreen for a period of time, the sunscreen effect will be damaged due to some physical means, such as washing your face, sweating, wiping, etc., and the sunscreen effect will be weakened over time. The purpose of reapplying sunscreen is to fill the damaged isolation layer and restore the original sunscreen effect of the sunscreen.

How to reapply sunscreen

1. Sunscreen spray

Use oil-absorbing tissue or paper towel to gently press the face to absorb excess oil and sweat. Spray the sunscreen spray 20 to 30 centimeters away from the face, and let the face catch the falling sunscreen spray. Repeat two or three times. The reason for using sunscreen spray is that it forms a film quickly, and you don't have to worry about ruining your makeup when applying sunscreen.

2. Spray-on sunscreen

If you are not wearing makeup, it is recommended that you use sunscreen to reapply. First, spray your face with a moisturizing spray and gently press to clean it. Then spray it again to slightly moisten it, and then apply sunscreen on your face by patting it. When applying sunscreen on your face, you must apply it in small amounts and multiple times, and pay attention to patting it evenly. After the sunscreen forms a film, you can then apply foundation.
