In fact, our skin has a natural epidermal barrier, this barrier not only protects the skin from external mechanical and chemical stimuli, but also impedes the absorption of the active ingredients of the drug, so that masks, serums and other skin care products can only stay in the epidermis, can not reach the dermis. Deep skin is not nourished, of course, how many masks a year are useless. Today, we will talk about the hydrazine needle, recently very popular, the background consultation is also very much. And Professor Lu sent sugar, the end of the article has a real person out of the video, and there is a full process of water light injection. Water light injection, also known as water light needle, deep water film, water light anti-aging, etc., because of water light injection fast-acting, minimally invasive, do not need to recover and other advantages, initially used by some stars to attend important occasions before the first aid skin beauty methods, so also called the Korean artists needle. The treatment principle of hydrafacial injection Hydrafacial injection is essentially a transdermal introduction technique of drugs, which is an application of mesotherapy in skin beauty and facial rejuvenation. Mesotherapy is a therapeutic method of injecting drugs directly under the skin to achieve therapeutic purpose, which was proposed by French doctor Michel Pistor in 1958. Initially used to treat vasculitis, muscle pain, etc., it is now widely used in the field of cosmetic surgery. Earlier injections were made using ordinary single-tip syringes, with the doctor manually controlling the amount and depth of injection; nowadays, most of the hydrafacial injection instruments are 31G microfine needles, which drastically reduces bleeding, redness, swelling and pain from injections. Computerized control of the injection volume, precise and uniform, negative pressure free of overflow, will not be injected into the level below the fixed depth. Hyaluronic Acid (HA), also known as hyaluronic acid, is responsible for the skin’s moist, supple and elasticity. HA is an acidic mucopolysaccharide secreted by the skin’s fibroblasts, which is the most powerful water-retaining substance in nature. However, as we age, the ability of fibroblasts to synthesize HA decreases, and the skin’s HA content gradually decreases, resulting in dry skin and fine lines. Because the molecular weight of HA is relatively large, it cannot pass through the epidermal barrier, so the HA in the skin care products we usually rub can only replenish the water in the epidermis and the stratum corneum. Hydrographic injection is injected into the dermis layer of small molecules of HA, the deeper layers of the skin become more water retention, of course, the light feeling of water blinkingbling ~ this is why it is called “hydrographic” needle reason. The medication used in hydrafacial injections is a small molecule, non-cross-linked HA-based solution. Depending on the specific skin condition, other ingredients can be combined with hyaluronic acid for a combined effect. The process of hydrafacial injection Hydrafacial Q&A Q: How much does it hurt to have hydrafacial injection? A: The pain is tolerable without anesthetic. Generally there will be surface anesthesia to reduce the injection pain, so that everyone “painless” beauty. Q: Is it safe to use hydrafacial injection? A: As mentioned above, hyaluronic acid is a strong water retention substance in the human body, which can be completely absorbed by the human body, and the injection level of hydrafacial injection is the dermis, so it is very safe. Q: How long can the effect of hydrafacial injection last? A: As the water light injection is a shallow injection, in order to inject the skin surface does not appear bulging, can only be injected easily dispersible small molecules of hyaluronic acid, and the small molecules of HA are easy to be metabolized and decomposed by the skin. So the maintenance time will not be like hyaluronic acid injection rhinoplasty maintained to half a year. Hydrographic injection generally about a month need to carry out supplementary injection, injection 3 times, the effect can be maintained for a year. Q: What are the precautions for hydrafacial injection? A: Hydrographic injection is a minimally invasive treatment, you should try to avoid menstruation, such as taking aspirin and other anticoagulants, you need to inform the doctor. If there are wounds on the face and severe acne pimples, care should be taken to avoid infection. There is no need for special care after the operation, pay attention to sun protection, avoid alcohol and strenuous exercise can be.
