Does the spray hydration device really work?

The spray hydrating device is actually the facial steamer from a long time ago. It just changed to a more high-sounding name to keep up with the development of the situation. The product and effect are not much different from the facial steamer. This name sounds more high-tech and instantly became more fashionable. It also spawned more hydrating devices. Many people are also worried about whether the spray hydrating device can really be effective and whether it will have bad side effects on the skin. Let's learn about it together below.

The oldest "facial steamer" is actually the hot towel that everyone uses frequently. When you are physically and mentally exhausted, lying on the sofa and applying a hot towel to your face can relieve your tired body and relax your mind. Beauty instrument manufacturers were inspired and invented the sprayer. Early sprayers were mainly used in beauty salons. Consumers who often go to beauty salons should be familiar with them. Sprayers are standard equipment in beauty salons.

Sprayers are divided into cold spray and hot spray. Somewhat different from what everyone knows, beauty salon lotion is not mainly used for hydration. The purpose of thermal spray is mainly to promote skin absorption and help remove blackheads. Thermal spray can increase the temperature of the skin surface, promote blood circulation, open pores, and increase the skin's absorption capacity. After thermal spraying, the essence is introduced, and the effective ingredients are more easily absorbed and utilized by the skin. After the hot spray, the skin temperature rises, some stubborn blackheads and whiteheads absorb water and loosen, and the cuticle softens, making them easier to remove.

Cold spray is mainly an auxiliary means of treating sensitive skin. The cool water mist can quickly stabilize sensitive, red and hot skin, which has a similar effect to ice compress, which is calming.

Is the Nano Spray Hydrating Device Useful?

Smart businessmen saw the business opportunity of this most basic instrument in beauty salons. They first shrunk it down, then made it very exquisite, and added high-tech concepts. This device was transformed into an expensive nano-spray hydrating device, and the businessmen created a new theory for it.

This theory includes: traditional sprayers and facial steamers spray large water droplets, while the water mist sprayed by the nano spray hydrating device is very small, only 1-5 microns (1 micron = 1000 nanometers) in size. The water mist particles are small and can be directly absorbed by the skin, which can better replenish moisture for the skin. It sounds reasonable. However, this theory ignores a common sense: the diameter of a water molecule is 0.4 nanometers, which is already nanometer-level. It can be absorbed by the skin without these so-called nano-hydrating devices. These hydrating devices simply make the water mist finer, making it more comfortable when sprayed on the face, but they are of no help in terms of moisture absorption. In terms of hydration, it only adds more water to your face, which is similar to the effect of flushing your face with water.

When in use, some nano sprayers allow you to add some toner and essence, but they cannot promote the absorption of these ingredients. The effect is almost the same as applying it directly on the face with your hands.

In addition, we often think that hydration and moisturizing are the same thing, but in fact, hydration and moisturizing are two different concepts. The main function of the skin care products we use is moisturizing, which prevents the evaporation of moisture inside the skin. Hydration and moisturizing are different. Hydration means replenishing moisture for the skin. The moisture of the skin is replenished very little through skin care products. Although the skin care products used contain a lot of moisture, most of it evaporates and very little is actually absorbed by the skin. So, where does the skin's moisture mainly come from?
