Can I use sunscreen instead of isolation cream? Is sunscreen an isolation cream?

Sunscreen and isolation cream are often confused. They are two different products. Sunscreen is a skin care product used to prevent ultraviolet rays, while isolation cream is a makeup product that isolates makeup and is used as a base before makeup.

Sunscreen is not a substitute for protection.

Isolation cream does not have the function of sun protection. It is mainly a cosmetic product used to adjust skin color and modify skin blemishes. Sunscreen is more professional and effective than isolation cream in sun protection. Sunscreen is usually transparent and has no effect on modifying skin color. Isolation cream will add some functions to adjust skin color. It has richer colors and a generally low sun protection index, which can play the role of isolating makeup.

Whether a general isolation cream can protect against the sun depends on whether the product has a sun protection index. If the isolation cream has a certain sun protection index, then its essence is sunscreen. If not, it can be used as a makeup primer. Sunscreen products are used to protect against ultraviolet rays (UVA and UVB) in the sun, and are generally divided into physical sunscreen and chemical sunscreen, as well as physical and chemical sunscreen. Because sunscreen cosmetics belong to special cosmetics, they must be safe and stable while achieving an effective sun protection index. Therefore, sunscreen products purchased through formal channels can basically be used with confidence as long as they have passed skin tests. Isolation cream claims to be able to isolate ultraviolet rays, dirty air and makeup. There are also some so-called radiation, but in fact they have no effect. Isolation cream is generally used before makeup to polish the skin and make it easier to put on makeup. If it can isolate ultraviolet rays and has a sun protection multiple, then it is essentially the same as sunscreen. If you buy an isolation cream with a sun protection effect, you don’t have to apply sunscreen. To see whether the isolation cream has a sun protection effect, you can see whether the outer packaging has a certain sun protection index, such as SPF and PA values. Therefore, sunscreen cannot completely replace isolation. In daily use, sunscreen and isolation cream can be used on the same makeup surface. Sunscreen is used after lotion or cream, which is the last step of skin care, while isolation cream is used after sunscreen, which is also the first step of makeup. However, no matter whether you use isolation cream or sunscreen, you must do a good job of removing makeup before going to bed at night. Because the chemicals in isolation and sunscreen products are difficult to dissolve in water and general facial cleansers, it is impossible to achieve a thorough cleansing effect by simply cleansing the face.

Generally, the bottle of sunscreen isolation cream will be marked with the corresponding sun protection index, such as SPF30, PA++. Such sunscreen isolation can be used instead of sunscreen. If only one of SPF and PA++ is marked, it means that its sun protection index is very low and it cannot achieve the sun protection effect at all. At this time, it is necessary to use sunscreen in combination. The main function of sunscreen isolation is to isolate fungi, bacteria, dirt and ultraviolet radiation in the air, but the SPF value and PA value of sunscreen isolation are not high. Some sunscreen isolation is also called primer, which can isolate makeup from our skin, and can also moisturize the skin, adjust the skin color, and make the skin color even, but its permeability is not very good, so you must remember to remove makeup. Sunscreen is a professional sunscreen product, which is generally divided into physical sunscreen and chemical sunscreen. These two sunscreens will produce an oxidation reaction with ultraviolet rays, which can well isolate the external ultraviolet rays from the skin, effectively prevent and avoid the skin from being sunburned and tanned, and thus play a role in protecting the skin. If you need to engage in outdoor activities for a long time, you cannot use sunscreen instead of sunscreen. If you generally stay indoors, you can use sunscreen instead of sunscreen. The sun protection effect of sunscreen is not as good as that of sunscreen.

Sunscreen and barrier cream can form a protective film on the skin. Sunscreen can effectively resist ultraviolet rays before barrier cream. Sunscreen must be applied half an hour before going out, and reapplied every 2 hours outside, patting lightly.
