The steps of hydrafacial injection are cleansing, surface anesthesia, and injection. The main ingredient of hydrafacial injection has small molecule hyaluronic acid, which can make the skin more hydrated and tender, with hydrating as well as moisturizing effects. Moreover, while replenishing small molecule hyaluronic acid with hydrafacial injection, some other ingredients can also be added to achieve different effects. For example, VC can be added to whiten the skin, and Botox can be added to remove wrinkles. 1. Cleansing: Before injecting hydrafacial injection, you need to clean your face thoroughly to make the pores of your face spread out and remove some dust and harmful ingredients on the surface. 2. Surface anesthesia: Because the injection of hydrafacial injection is with a machine, with a very thin needle into the skin, there will be a tingling sensation, so you can use topical numbing medicine on the surface of the skin before the hydrafacial injection, to relieve the tingling sensation. 3. Injection: The machine used for the injection of hydrafacial injection generally uses nine rows of needles to directly inject the drug components of hydrafacial injection, into the subcutaneous, so that the slow release of the drug can be injected into the appropriate level of the components of the drug. Because the treatment is invasive operation, the injection process pay attention to the whole aseptic operation, to avoid infection. The use of water light injection is recommended to go to a regular hospital, under the guidance of a professional doctor.
