Should I use primer or foundation first?

For female friends, isolation cream and liquid foundation are no strangers, because no matter whether you wear makeup often or not, you must have these products at home in case of emergency. Primer and liquid foundation are two products that you need to use during the makeup process, whether it is light makeup or heavy makeup. So, should you use primer or foundation first? The following will give you a detailed introduction!

1. Use primer first and then apply liquid foundation

The difference between liquid foundation and isolation cream is that isolation cream is a skin care product used to isolate ultraviolet rays, makeup, radiation, etc. It is used after using facial cream and is only used during the day, not at night. Liquid foundation is a kind of makeup that is used after using isolation cream. It is mainly used to cover blemishes and improve skin tone. They are two different things. However, liquid foundation also has an isolation effect, but you must use isolation cream before using it to avoid hurting the skin.

2. The role of isolation cream and liquid foundation

Isolation cream can protect the skin. Isolation cream has an isolating effect on ultraviolet rays, which is equivalent to sunscreen. The sunscreen used in isolation cream is the same as that in sunscreen. Sunscreens are divided into organic sunscreens and physical sunscreens. Organic sunscreens interact with ultraviolet rays, turning ultraviolet rays that are originally harmful to the skin into harmless ones; physical sunscreens mainly rely on the principle of reflection to block ultraviolet rays.

The function of liquid foundation is to cover blemishes, spots, and make the skin look smooth and even. (The premise is to apply it evenly) Therefore, girls with many spots, blemishes, and acne scars should try to use liquid foundation when going out to put on makeup, instead of just applying a primer and then foundation or loose powder. Of course, if your skin doesn’t have any acne or freckles, you can apply foundation or loose powder after using the primer, but you don’t need to apply liquid foundation. This way your makeup won’t look heavy. Liquid foundation is a liquid foundation, which is suitable for neutral, combination and oily skin.

3. The correct order of using cosmetics

The order of applying skin care products should follow the principle of small molecules to large molecules. From the appearance, it should be applied according to the thickness of the skin care products, from thin to thick.

Sunscreen is different from isolation cream. Isolation cream can even out skin tone and isolate dust, while sunscreen mainly prevents damage from ultraviolet light. The molecules of sunscreen are larger, so apply isolation cream first and then sunscreen. At present, many products on the market include the functions of isolation and sun protection, which is two-in-one and more convenient.

The correct order for using skin care products is generally: facial cleanser - toner - eye cream - essence - lotion - primer - sunscreen - foundation.

If you sweat after putting on makeup and need to reapply sunscreen, you can choose powder or foundation with an SPF.
