The high-pressure jet method used by needleless water light is more comfortable than the needle, but obviously not as convenient as a wipe on the face to come fast. This involves a fundamental problem, although they are called water light, but regardless of the needles or nacre, all belong to the category of medical beauty treatment, while the application of water light, just ordinary cosmetics. What is an applied hydrafacial? As the name implies, a single application on the face is all that is needed. Cosmetic developers usually design their products to look similar to hydrafacial, and use the gimmick of hydrafacial for marketing, so that beauty seekers who have not undergone hydrafacial treatment are confused by the concept and mistakenly believe that it can achieve the effect of hydrafacial in medical beauty. Whether it’s a hydrafacial needle penetrating the mesoderm to replenish nutrients or a needleless hydrafacial dipping into the basal layer to replenish nutrients, it needs a way to open the skin’s channels. And applied hydration without needles, non-high-pressure, without the use of electroporation, only coated, it can have an effect? Yes, but it is the effect of ordinary moisturizing products, although it also contains small micro-molecules of hyaluronic acid, but because it does not open the skin channel, these hyaluronic acid only in the epidermis of the stratum corneum, to put it bluntly is a moisture serum only. Is it necessary to use it? If you just treat it as a moisturizing serum, and the effect is good and the price is suitable, of course, you can continue to use it, otherwise we insist on daily maintenance of the skin for what purpose? But unlike other hydration treatments, other hydration is hyaluronic acid-based attached to other nutrients, so the effect depends on the hyaluronic acid. But applied hydration does not need to care how much hyaluronic acid, hyaluronic acid effect is good, because no matter how good hyaluronic acid is, it will stay in the stratum corneum because there is no access to the skin, and it is also destined to be unable to be absorbed by the body, and cannot achieve the effect of moisturizing and locking water. So why do most manufacturers use hyaluronic acid in their hydrating products? In fact, it is not completely useless, but occasionally has the opposite effect. Although hyaluronic acid stays on the surface of the skin, hyaluronic acid can still store water through its own characteristics to moisturize the skin, but the effect is usually only 8 hours. So why does it have a counter effect? That’s because the premise of all the benefits I just wrote about requires you to be in a situation where your skin is well hydrated. If you don’t do a good job of hydrating your skin and use an applicator hydration when your skin is dry, it will not only fail to moisturize you, but it will also suck up the little moisture you have in your skin itself, while possibly causing skin sensitivity, redness, rashes, itching, and peeling. What are the main ingredients in an applicator hydration? The best way to analyze a product is to look at its formula. By carefully studying the list of ingredients of a part of the regular brand of applicator hydration, you will find that a large number of them contain moisturizer ingredients such as methyl glucosamine polyether, dipropylene glycol, propylene glycol, butylene glycol, and many of them are also added in front of hyaluronic acid. This just confirms what I said above, this kind of smear water light is good, the least need to care about may be hyaluronic acid, the amount of other ingredients ration may be more important. However, when I researched some of the ingredients of the smear-type hydration needle sold by micro-merchants, it was basically water and glycerin, hyaluronic acid was not at all, and because of the lack of other moisturizing ingredients, it was not even qualified to act as a general moisturizer. Tips: Does needleless hydration and smear hydration belong to the category of hydration needles? In fact, strictly speaking, needle-free hydration does not belong to the category of hydration needles. Needle-free hydrafacial is different from hydrafacial no matter how it is injected, the nutrients injected, or the final treatment effect. Because needleless water light uses high-pressure spray technology to import, so the depth can only penetrate the stratum corneum, in fact, it is difficult for nutrients to enter the dermis from the epidermal micropores, and at the same time, because the use of non-injection level small micro-molecule hyaluronic acid, transaminic acid original solution, etc., the effect can only play to improve edema, clean pores, hydration, and the real water light needle is still far away. As for the smear type water light, just marketing rubbing the hot spot of the water light needle, as a gimmick, the regular smear type water light should be able to be used as a moisturizing serum or moisturizing mask (depending on the role of other ingredients in addition to hyaluronic acid), the informal smear type water light is not even qualified as a moisturizer!
