Nowadays, many MMs like to use cream, but they don't know much about what cream is and what it does. When it comes to cream, we have to talk about its origin first. In fact, the earliest cream in China is Ponzi's cream. At that time, the slogan was "isolate ultraviolet rays, isolate dirty air and isolate makeup". These three functions have also become the slogan of other creams in the future, and even in the minds of many consumers, these are the basic functions of creams. However, the cream at that time was only a sunscreen with a very low SPF value, but this ordinary sunscreen unexpectedly became popular after changing the door of the cream, so more and more creams came out later.

Can cream really isolate ultraviolet rays, dirty air and makeup, or can it isolate computer radiation? No matter how effective the cream is, the essence is still cream. Cream can't really isolate the so-called dirty air and makeup, because it can't form an "iron wall" on the face, so the dirty air and makeup will inevitably fall on the face more or less. You can't think that everything will be fine after using the cream, and you don't have to worry about getting worse!

Isolation cream does have an isolation effect on ultraviolet rays, and its essence is sun protection! The sunscreen used in sunscreen is the same as that used in sunscreen, and it is usually divided into two categories: organic sunscreen and physical sunscreen. Organic sunscreen works with ultraviolet rays to change the wavelength of ultraviolet rays, so that ultraviolet rays harmful to the skin become harmless; Physical sunscreen (titanium dioxide, zinc oxide, etc. ) mainly uses the principle of refraction to block ultraviolet rays. From this perspective, sunscreen and sunscreen are the same thing.

Protecting computer radiation is also the slogan of many sunscreens now, but it is difficult to do it with the current technology. Most of the computer radiation belongs to low-frequency radiation, with a wavelength of about 6.5cm, while isolation cream and sunscreen cream are mainly aimed at ultraviolet rays with a wavelength of 0.0 1-0.40 micron. It can be seen that the cream has no effect on computer radiation at all. In addition to radiation, computers can also cause harm to human body, and the electrostatic effect of computer screens will absorb a lot of dust in the air. When using computers, our skin is in a rather dirty environment. As for dust protection, ordinary creams and lotions can do it. Therefore, MMs who often use computers don't have to use cream. It is more affordable to wash their faces and wash away some dust after using computers.

Moisturizing cream, as its name implies, is not so effective in moisturizing the skin, but it needs to be moisturized before rubbing.
