Which should I use first, foundation or primer

There is a big difference between foundation and isolation cream, and they cannot be used as the same thing at all, because isolation cream does not have the effect of concealing blemishes. Isolation cream only plays an isolating role and can prevent some cosmetics from penetrating the pores and clogging the pores. Therefore, when using them in daily life, you should use isolation cream first and then foundation, to ensure that it will not clog the pores and keep the pores clean.

The order is to use primer first and then apply 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.

What is the difference between liquid foundation and primer?

Nowadays, many girls like to use primer, but they don’t know much about what primer is like and what functions it plays. When talking about isolation cream, we have to talk about its origin first. In fact, the first isolation cream of this type in China was the isolation cream launched by Pond's. The slogan at that time was "Isolate ultraviolet rays, isolate dirty air, and isolate makeup." These three functions have also become the common promotional slogans of other isolation creams in the future, and even in the minds of many consumers, these are also the basic functions of isolation creams. However, that isolation cream at that time was actually just a sunscreen with a low SPF value. However, this ordinary sunscreen became unexpectedly popular after it was transformed into an isolation cream, so more and more isolation creams came into the market later.

The difference between liquid foundation and isolation cream is that isolation cream does have an isolation effect on ultraviolet rays, and its essence is sun protection!!! The sunscreen used in isolation cream is the same as that used in sunscreen, which is usually divided into two categories: organic sunscreen and physical sunscreen. Organic sunscreens interact with ultraviolet rays, changing their wavelengths and turning them into harmless ones that are harmful to the skin. Physical sunscreens (titanium dioxide, zinc dioxide, etc.) mainly rely on the principle of refraction to block ultraviolet rays. From this perspective, primer and sunscreen are the same thing.

Protection against computer radiation is also the promotional slogan of many sunblock creams nowadays, but this is difficult to achieve with current technology. Most of the computer radiation is low-frequency radiation with a wavelength of about 6.5cm, while isolation cream and sunscreen mainly target ultraviolet rays with a wavelength of 0.01-0.40 microns. It can be seen that isolation cream has no effect on computer radiation at all. In addition to the harmful radiation from computers, the static electricity effect of computer screens can absorb a large amount of dust in the air. When using a computer, our skin is in a rather "dirty" environment. As for protection against dust, ordinary creams and lotions can do the job. Therefore, ladies who often use computers do not have to use isolation cream. It is more economical to wash your face after using the computer to wash away some dust.
