Do you need sunscreen all year round

Sunscreen should be used in all seasons of the year, because no matter in spring, summer, autumn and winter, ultraviolet radiation has different degrees. However, it should be noted that sunscreen with different sun protection index can be selected in each season. In summer, ultraviolet radiation is strong. In hot weather, sunscreen with higher sun protection index and a little more PA + can be used. In spring and winter, the weather is not so hot. Ultraviolet radiation It's not that strong, so you can use sunscreen with a slightly lower SPF.

Precautions for use

1. Applied part

When applying sunscreen, do not ignore the neck, chin, ears and other parts to avoid uneven skin color.

2. Cleaning products

Be sure to thoroughly remove the sunscreen every night, so don't take sunscreen to rest and sleep.

3. Use enough

Sunscreen is not effective when it is applied, but only when it reaches a certain amount can it exert its effect. Generally, when the amount of sunscreen applied on the skin is 2 mg / cm2, it can achieve the proper sunscreen effect. It should be noted that the SPF value cannot be accumulated. Two layers of SPF10 sunscreen have only one layer of SPF10 protection effect.

4. Do not mix different brands of sunscreen

Mixed use increases the possibility of skin allergies. The ingredients of different brands of sunscreen are inconsistent. If they are mixed and overlapped on the skin, they may cause mutual interference or rejection, reduce the sunscreen effect, and even cause skin allergy.

5. Keep in mind

If it is heated or exposed to the sun for a long time, the effect of sunscreen may be reduced. Do not use the deteriorated sunscreen cosmetics, because it not only reduces the sunscreen effect, but also is more likely to stimulate the skin.

6. Pay attention to the dead angle of sun protection

When applying ordinary sunscreen, the skin of eyes and lips also needs attention. But if there is no instruction, or use sunscreen for the eyes, do not use it on the skin around the eyes.
