In the circle of friends, often see people shouting about the magical effects of the application of water light needles, beauty salons, cosmetics merchants and even some bath centers are beginning to recruit customers to promote. There are more and more products of this concept, and there is even a concept term such as “water light muscle”. What exactly is a hydrafresher? What is a smear-type hydration needle? Is it really effective? The actual fact is that you will be able to unravel the mystery of hydrafacial needles and the applicator type hydrafacial needles. 1. What is hydrafacial injection? The actual name of the product is not “water” nor “light”. “The real scientific name for it is Intradermal Injection, which is, frankly speaking, an intradermal injection, a relatively common medical technology. The water light needle is the use of negative pressure needle in the skin dermis inject hyaluronic acid (hyaluronic acid), botulinum toxin and other cosmetic injections, in order to achieve different cosmetic effects. Generally speaking, there are two types of injections: machine injections and manual injections, and injectable beauty belongs to the medical beauty category, which can only be carried out in medical institutions. The following is a demonstration of the principle of hydration injection (machine injection) (image source network): as shown above, first insert the needle into the dermis of the skin, after pumping to generate a negative pressure, and then the injection solution (hyaluronic acid, botulinum toxin, etc.) into, just a little push, you can breathe the solution into the skin through the negative pressure, so complete an injection. Is the effect of hydrafacial injection good? In fact, the so-called “hydration needle” is just an instrument, the main role is to transport the beauty injections to the dermis, so the real effect is still its injection of drugs, such as hyaluronic acid for hydration, collagen for filling, botulinum toxin for wrinkle removal and so on. So theoretically speaking, the effect of hydration injections is far from being as exaggerated as advertised, but compared to daily applied skin care products, hydration injections can indeed better promote the absorption of beauty ingredients, and depending on the injected ingredients can achieve the corresponding beauty effects. What is a hydrafacial injection? With the popularity of the concept of hydration needle, a series of self-proclaimed “smear-type hydration needle” products under the name of “no injections, moisturizing skin care” waving through the market, the momentum of sweeping the hydration needle market. So what is this so-called smear type hydration needle? The actual effective as advertised? We’d better start with the conclusion that the smear type hydration needle is purely a gimmick, that is, under the name of hydration needle to fool some of the girls who do not have enough financial ability or worry about the side effects of injection. The so-called “smear type water light needle” in the end what is it? The first look at Taobao, WeChat circle of friends sold in the smear type hydrophobic needle are what products. The following chart, are the so-called smear-type hydration needle: that is, a syringe-like packaging container, filled with some transparent essence, generally add hyaluronic acid (hyaluronic acid). For example, below is the ingredient list of a smear-type hydration shot. As you can see, it is mainly a polyol-based, plus some hyaluronic acid moisturizing essence only. The human skin is actually very dense, its surface has a strong “defense” of the stratum corneum, this external application of hyaluronic acid extract, generally does not have the ability to penetrate the skin, if it is a small molecule of hyaluronic acid, it is possible to have a partial penetration of the skin, but the problem is that the amount of this penetration is very small, just by applying a few milliliters of hyaluronic acid solution at a time, it is not possible to get through the skin. The problem is that the amount of hyaluronic acid penetrated is very small, just by applying a few milliliters of hyaluronic acid solution at a time, it is impossible to play the effect, let alone compared with the hydration injection. In general, the application of water light needle may slightly moisturizing effect, but compared to the effect of water light needle can be almost negligible, as for the other efficacy of the proclaimed role is basically unreliable. And on that point moisturizing effect, if you use some moisturizing mask or other large bottle of moisturizing serum, the same can achieve this effect, the key is the price than the smear type hydration needle do not know how much cheaper ah! In addition to the convenience of carrying, this so-called smear-type hydration needle is really hard to think of what other benefits, but the question is whether you are willing to spend money to use a product that is convenient to carry but has little effect? What are the side effects of the smear type hydration injection? Since an applicator is so much a smear type of essence/water product, it doesn’t matter what the potential side effects are compared to a hydration shot. The side effects of a smear-type hydrafacial are equivalent to the side effects of hyaluronic acid extract or lotion to the extent that repeated, excessive application may trigger skin allergies, causing local skin rashes, itching and other discomfort. But also need to add a point of clarification, some of the girls who have used the applicator hydration needle may say that they use a certain applicator hydration needle product effect is really better than the effect of ordinary applicator serum, and what is the reason for this? Here is a simple science. As shown in the skin structure diagram below, the human skin surface with a layer of dense stratum corneum, stratum corneum to protect the body’s organs and tissues from sun damage, to prevent the loss of nutrients in the body, but also to prevent skin care products containing large molecules of nutrients such as hyaluronic acid, collagen into the basal layer to play an effective role. Commonly applied skin care products use a certain amount of chemical agents to corrode the stratum corneum to promote the penetration of nutrients into the basal layer of the skin. The ideal chemical permeation promoter should generally meet the following points: 1, non-toxic to the skin, non-irritating, non-allergic; 2, rapid onset, renewable activity and predictable duration; 3, no pharmacological activity in the body; 4, to prevent the loss of body components while promoting permeation; 5, when removed from the skin, the barrier function of the skin should be restored as soon as possible and completely; 6, mutually compatible with excipients and drugs; 7, beauty effect . Unfortunately, however, the ideal chemical promoter does not exist, and the degree of effectiveness of chemical promoters is always based on the degree of damage to the stratum corneum. Controlling the damage to the stratum corneum to ensure the self-repair of the skin barrier and promoting the effective absorption of nutrients are always the two contradictory poles that need to be balanced in applied skin care products. The continued use of excessive chemical promoters or the use of poor chemical promoters may enhance the effectiveness of skin care products for a short period of time, but long-term use will bring irreversible damage to the stratum corneum, resulting in fragile, allergy-prone, dry and rough skin. The reason why individual smear-type hydration needle products have far better effects than ordinary smear-type serums is, I believe, no longer need to explain it. Don’t be fooled by the so-called “water light”? Not only is there a smear-type hydration needle, nowadays the word “hydration” to do publicity products are endless, such as hydration cream, hydration mask and so on. In a treasure search for the word water light there are more than 200,000 return results, unknown brands, some big brands also did not miss the opportunity to apply the word water light. For example, a treasure Ou family directly out of the water light into the skin care series, and claimed to be the same model Fan. I am not sure if Fan is really using, as for the efficacy of well, we have already done a full interpretation of the “water light era” of the product principle, I believe that intelligent as you, must be able to understand the. Conclusion: First of all, it should be acknowledged that the word person who invented or translated the hydration needle is definitely a genius. Water and light, both are the two most useful substances for earth creatures. Water is the origin of life. And light comes from the sun and contains energy. Without water and light, there would be no life on Earth. The combination of these two great substances created a word that has become one of the hottest words in the domestic cosmetics market, with major brands scrambling to come up with products related to water and light, and consumers also seem to eat it up. One word tops hundreds of millions of advertising dollars, how is a day to describe the. And as far as the product is concerned, the water light needle as a microplastic product, indeed has a good effect, but also to the love of beauty of women to provide a convenient and fast road. But you need to have a pair of eyes to be able to avoid the numerous traps in this mixed market and find the few safe entrances. As for the applicator hydrophobic needle, hydrophobic cream, hydrophobic mask and other “hydrophobic” derivatives, it can only be said that in the name of hydrophobic needle to fool some girls who do not have sufficient financial means or worry about the side effects of injection gimmick products, conscience a little to achieve the efficacy of ordinary applicator skin care products and masks, unscrupulous a little will only bring The skin is permanently damaged, and the loss is not worth the gain.
