Do I need to reapply sunscreen indoors?

Sunscreen needs to be reapplied indoors.

Research has long shown that UVA rays in ultraviolet rays are extremely penetrating. Regardless of whether it is sunny or cloudy, as long as there are glass windows, they can easily penetrate into the room, and the area 2-4.5 meters away from the window is all in the light radiation zone. It will also cause damage to the skin, so even if we stay indoors, we cannot slack off on sun protection. We need to use a full-spectrum medium to high-power sunscreen product with a sun protection index of at least SPF25 and PA++ or above, and it needs to be reapplied every 2 to 3 hours.

How to reapply sunscreen indoors

Step 1: Spray your face with spray, just spray it lightly, a little farther away from your face. The mist sprayed on your face will be finer and will not destroy your original sunscreen because of too much. Allow the spray to remain on for a few seconds. The function of spraying is to take away excess oil and heat from the face, making the face refreshed and cool.

Step 2: After a few seconds, unfold a clean tissue and press it on your face. Note that you should press it, not wipe it.

Step 3: After drying the moisture on your face, you can take out the sunscreen from your bag and apply sunscreen.
