The correct way to use sunscreen

1. In daily life, you can choose a sunscreen with an SPF value between 10-15 or SP+.

2. When shopping, you can choose a sunscreen with an SPF value between 15-20 and SP++

3. When traveling, you can choose a sunscreen with an SPF value between 20-30 and SP+++

4. When swimming or sunbathing, you need to use a sunscreen with an SPF value of 30 or above (waterproof), and reapply it every 2-3 hours. If you engage in underwater activities, reapply it every 80 minutes.

5. Sunscreen takes a certain amount of time to be absorbed and take effect, so it should be applied 20 to 30 minutes before going out.

6. The SPF value of sunscreen cannot be accumulated, and it cannot be used after applying makeup. When reapplying sunscreen, it is best to remove makeup first and then apply it.

7. Ultraviolet rays can damage the skin even in winter, indoors, and on cloudy days. On cloudy days or in the shade, the intensity of ultraviolet rays will only be reduced by about 30%, so the use of sunscreen should be maintained in all seasons, rain or shine.

8. Sunscreen needs to reach a certain thickness to be effective. If it is too thin, it will not achieve the desired effect, and if it is too thick, it will cause burden to the skin. The general application amount is 2 mg per square centimeter. 2-2.5 grams should be applied to a pair of arms at a time, and 1-1.5 grams should be applied to the face at a time.

Can sunscreen be applied directly?

Many people have some misunderstandings when using sunscreen, which may lead to the appearance of pigmentation. You must remember that before using sunscreen, you must first do basic care and thoroughly clean your skin. Then, be sure to apply a layer of base cream according to your skin type, such as isolation cream or lotion. Otherwise, under the sun, it is easy to develop pigmentation spots, which will also clog pores and hinder the normal metabolism of the skin. This is because sunscreen is harmful to the skin. The higher the SPF, the greater the damage. Therefore, in addition to lotion and emulsion, it is best to use isolation before sunscreen.

Therefore, it is recommended that friends take care of their skin before applying sunscreen.
