First of all, for everyone to popularize the concept of “injecting water light and smear water light”. 1, injection of water light Water light injection is actually a kind of injection skin care methods, with the help of a special instrument “water light gun”, the nutrients injected into the dermis immediately under the epidermis. The injection can make the skin become moisturized, bright and so named. 2, coated water light coated water light is the emergence of recent years, belongs to the category without the help of water light gun. Just borrowed the concept of the hydrafacial needle, with a syringe-shaped packaging container, which is loaded with some essence. In fact, it is the essence changed a vest, with the help of the concept of hydrazine needle to sell products. Secondly, what is the difference in the usage of the two types of hydrafacial injections? Injectable hydrazine injection is through the form of injection, the skin needs nutrition into the skin, through the operation of the machine, only a little push, you can through the negative pressure will be injected into the skin of the solution, but also can control the depth of the injection and the amount of injection. Individual operation is not recommended, you need to go to a regular hospital to let the doctor operate. And what about the applicator water light? It is actually a kind of topical skin care products, normal cleansing, pat toner, take out the “application of water light” applied, and then rubbed on a mild cream to lock the water, this can be. No need to let the doctor operation, just like applying skin care serum, individuals can operate at home. Finally, does it work or not? Injecting water light through the direct injection of water light needle can make up for the loss of hyaluronic acid due to various reasons, short time to enhance the hydration and radiance of the skin, and increase the elasticity of the skin. The results will be especially noticeable on dry, fine-lined skin. And what about applicator hydration? It is claimed that “only need to be applied to reach the base of the skin, super hydration, do not need to import”. Is it really so “magical”? The so-called “application type hydration injection”, in fact, is a kind of topical skin care products. If: the nutritional composition of the smear type of water light and the same injection of water light, the main ingredient is a small molecule of hyaluronic acid, it is impossible to enter the skin through the way of smear! The reason is: human skin is actually very dense, its surface has keratin and other components of the solid “defense”, the application of small molecules of hyaluronic acid is difficult to penetrate into the muscle base, that is to say, only by way of application can not be achieved by injecting the effect of hydrafacial.
