The sun is sunny in winter. Do you need sunscreen?

Many people think that there is no need for sun protection when the temperature is low and there are few sunny days in winter. In fact, sun protection should be "exposed to rain and dew" all year round, and sun protection should not be ignored in winter.

Selection of sunscreen in different seasons

Ultraviolet rays exist all year round, and the sunshine appears mild in winter, but the ultraviolet rays are only about 20% weaker than those in summer, and still do harm to human skin and eyes. But the standard of sun protection in spring and summer is also different.

Key points of sun protection in summer: choose sun protection products with stronger protection, strong oil control and good waterproof and sweat resistance. The feeling of use is refreshing and not heavy, and it is best to form a film quickly after application. At the same time, take more umbrellas and wear more hats when going out.

Key points of sun protection in winter: ultraviolet rays in winter are not as strong as those in summer, and the sun protection index can be selected as a moisturizing sun protection product, with SPF between 15~30. Especially people with dry skin and mixed dry skin should abandon the refreshing sunscreen in autumn and winter and choose a heavy and moist sunscreen.

Usage and dosage in winter: As in summer, when you use sunscreen in winter, you need to apply it to your face about the size of a coin, and it will take half an hour to get the best effect. After applying sunscreen for several hours, the sunscreen effect will be weakened. If you are away for a long time, remember to apply sunscreen in time. Sun protection should be comprehensive and you can't cut corners.

Under what circumstances do you need sun protection?

Q 1: I have been working indoors. Do I need sun protection?

A: If you sit by the window, you need to wear sunscreen. Because ordinary glass can't block UVA in ultraviolet rays.

Q2: Do you need sun protection on cloudy days?

A: The intensity of ultraviolet rays will decrease on cloudy days, but it is still necessary to moderately prevent sun exposure.

Q3: Can sunscreen be replaced by sunscreen and liquid foundation with sunscreen value?

Answer: sunscreen must be used in sufficient amount, generally around 1- 1.5 ml. If you want to use sunscreen cream and liquid foundation with sunscreen value instead of sunscreen cream, then sunscreen cream and liquid foundation should also be coated with 1- 1.5 ml, then sunscreen cream and sunscreen cream can be coated so much. So use sunscreen!

In addition, pay attention to the expiration date of sunscreen. In general, the shelf life of sunscreen is 3 to 5 years, but it is best to use it after opening. After this expiration date, the sunscreen effect will be greatly reduced.
