Moisturizer - hyaluronic acid, is it really useful

author:adminrelease:2018-03-23

  Every man has his heart. In order to be beautiful, many female consumers choose to go to a plastic surgery hospital or a beauty salon for Hyaluronan, or Hyaluronic acid. Hyaluronic acid is the permanent weapon of many stars. But we can't help asking, does it really work? Will there be side effects?


  Hyaluronic acid, also known as hyaluronic acid, is an advanced polysaccharide, consisting of d-glucuronic acid and n-acetylglucosamine, and does not contain sulfur (which distinguishes it from other mucopolysaccharides). Because it has strong carrying capacity, it is reused by the beauty industry.


  Hyaluronic acid -- moisturizing king.


  In fact, hyaluronic acid is found in the connective tissue and the dermis of the human body. It is a transparent colloidal substance with powerful moisturizing function. Hyaluronic acid absorbs water more than 500 times as much as glycerin.


  Our skin is divided into epidermis and dermis. The dermis is like a sponge cake beneath a mousse cake, and the epidermis is the top layer of cream.


  The dermis is under the epidermis, and the main component is the matrix between fibers and fibers. The matrix can be combined with a large amount of water, which is an important material basis for maintaining moisture in dermal tissues. Hyaluronic acid is one of the most abundant matrix in the dermis, if in less hyaluronic acid dermal matrix, to cause a decline in moisture, causing dry skin, no luster and elasticity decreased, wrinkles, and so on.


  The epidermis is the outer protective barrier of the skin, with a normal water content of 20% to 35%. When the water content of the epidermis is reduced to 10%, the obvious skin dryness can occur: dull, fine grain, rough and desquamate, etc., and also can feel the skin discomfort, itching and so on.


  At this point, please use the hyaluronic acid as a moisturizer. When the ambient humidity is relatively low, the external hyaluronic acid can absorb moisture from the environment and "lock" on the epidermis; At the same time, a small number of hyaluronic acid penetrating into the dermis can absorb moisture from the dermis and transfer it to the epidermis to achieve the "internal and external" moisturizing effect.


  And other common moisturizing factor, such as propylene glycol, glycerin, urea, such as hyaluronic acid moisturizing effect, and the majority of hyaluronic acid preparation, no greasy feeling, can instantly after using form a film on the surface of the skin, make skin smooth and moist, so is widely used in all kinds of cosmetics.


  But the price of the cosmetics containing hyaluronic acid "expensive" (1-2 yuan and glycerol, urea) compared with, so from the price, hyaluronic acid is not necessarily moisturizing factor, the optimal choice.


  Moisturizing is not enough.


  Although hyaluronic acid is better than its peers, it is not enough to moisturize with hyaluronic acid. This is because the moisture is not simply to absorb the moisture to the skin, the real moisture needs to retain the moisture in the skin, as far as possible to prevent or delay the loss of moisture the skin, and smooth skin texture. As a result, a perfect moisturizer should include a moisturizer and a sealant and an emollient.


  Hyaluronic acid forms a water-rich membrane on the cuticle (or skin surface), while delivering water to the inside (skin) and outward (the environment). Therefore, when the environment is dry, it is necessary to rely on the sealant to reduce its moisture to the outside to keep moisture. The sealant can form a thin film on the surface of the skin, preventing water from "running", which is usually greasy, such as vaseline, mineral oil, and silicon resin derivatives.


  The emollient is the space between the outer layer of the outer layer of the epidermis, which makes the skin surface texture smooth and soft, which can reflect the efficacy and cosmetic effect of cosmetics in a short period of time. According to different internal characteristics, it can be classified as protective, lipid, dry or astringent. Hyaluronic acid, besides moisturizing, also has the function of a little emollient.


  In fact, the most well-regarded moisturizers in the market today are often "mixtures" of the three. Specific formulas are often used for specific skin types to regulate the ratio of water to oil. Therefore, when buying skin care products, you need to know your skin first, and then look for your own formula and dosage form!


  The injection is quick and difficult to maintain.


  External skin care products need to "rely on" the penetration ability and absorption of the epidermis to enter the dermis and even subcutaneously. But how to get the effective ingredients to penetrate the skin barrier has been a constant headache for researchers. It has to be said that there is no good way to get the hyaluronic acid into the "deep" just by smudging.


  Existing mature will hyaluronic acid into dermis and subcutaneous tissue is beauty "injection", namely by fine needle to hyaluronic acid into dermis and subcutaneous tissue, import quantity and different clinical effect.


  When injected, it can be used to fill the skin with small wrinkles or scars to restore skin level and elasticity. When injected, it can be used to reshape the local appearance, such as raising the bridge of the nose, repairing the nasal tip, chubby cheeks, full lips, repairing lips, trimming the chin, and so on.


  Although the clinical use of hyaluronic acid is used for filling, but after the injection of hyaluronic acid, with some moisturizing effect, the skin also becomes delicate and glossy. On the one hand may be increase the hyaluronic acid content in the dermis and subcutaneous tissue, may increase the moisture transmission to the skin, but is more likely to be injected hyaluronic acid for dermal stimulation increased for collagen protein synthesis, to let the skin become delicate luster.


  Since hyaluronic acid is a component of the body itself, it is safe to inject hyaluronic acid as long as it is used in normal medical institutions, and the effect is immediate. However, the disadvantage of hyaluronic acid is that it is absorbed by the human body, so it has to be reinjected every once in a while to maintain the effect.
