Needle-free hydrafacial uses a blast of nutrients that is introduced into the basal layer of the skin’s epidermis through the “jet technology” of a needle-free injector. The jet technology is a special device that accelerates a jet stream of micro-droplets of liquid and gas, creating a concave surface on the skin in the high-pressure area. As the skin stretches, the microtubules in the outer layer of the skin will then expand and form new microtubules, thus opening up access to the dermal layer of the skin. Under the operation of a professional physician in a regular hospital, there are usually no side effects. The difference between needle-free hydrafacial and hydration injections is that injectable hydrafacial is injected directly with a needle, while needle-free hydrafacial uses a low-pressure jet to introduce the drug into the subcutaneous. In general, when performing hydrafacial treatment, you need to avoid pregnancy, breastfeeding and menstruation, and people with a history of allergy to hyaluronic acid should not undergo hydrafacial injection. In addition, after the hydrafacial treatment must be diligent hydration, it is recommended to use medical beauty mask. After all, hydroluminescence is an invasive treatment and belongs to medical practice, so you must find a professional doctor to assess whether you can do it first and what kind of formula is effective before you can have hydroluminescence injections.
