How to choose sunscreen 7 points to teach you how to quickly choose the sunscreen that suits you

There are a wide variety of sunscreens on the market. Faced with professional terms such as SPF and PA on sunscreens and various brands, how do you choose sunscreen? Girls often wonder this question when buying sunscreen. A good sunscreen can effectively resist the erosion of ultraviolet rays on the skin and prevent the skin from being tanned by the sun.

Choose sunscreen based on ingredients

Sunscreen is divided into three types: chemical sunscreen, physical sunscreen and physical + chemical sunscreen. Physical sunscreen achieves the sun protection effect through physical refraction and reflection of light. Common ingredients of physical sunscreen are zinc oxide and titanium dioxide. Chemical sunscreen absorbs ultraviolet rays and converts light energy into heat energy on the skin surface through chemical reactions and releases it.

The choice of sunscreen should be determined according to the time of going out

Many girls who need to stay outdoors for a long time should choose sunscreen with a higher SPF multiple. SPF is the time the skin can resist ultraviolet rays. Generally speaking, SPF15 sunscreen can effectively protect the skin for nearly 4 hours. The higher the SPF multiple, the longer the protection time and the greater the protection it provides to the skin.

Sunscreen should be selected according to the amount used

The capacity of sunscreen needs to be selected according to the usage. Generally speaking, 50 grams of sunscreen will be used up within one month. Sunscreen must be used up within six months after opening. When sunscreen comes into contact with air, its quality will be affected. If the sunscreen is not opened, it can be used until the second year, otherwise it needs to be used up within six months.

Choose sunscreen based on oil content

Many girls have different skin types. Some girls have dry skin, some girls have oily skin, and so on. When choosing sunscreen, you must look at the oil content in the sunscreen. Girls with dry skin can choose sunscreen with a higher oil content, which can effectively moisturize the skin on their face; girls with oily skin should try to choose refreshing and moisturizing sunscreen. The high oil content in sunscreen will stimulate the oil secretion of girls with oily skin, which will lead to problems such as enlarged pores, acne, and floating makeup.
