"Needleless water light needle" forcibly squeezes the skin and injects nutrients through high-speed and high-pressure airflow. In this process, the skin will be overstretched, and the keratinocytes on the skin surface will be slightly damaged under the action of high-speed airflow.

The "needle-free water-light needle" will only be done for the second time every once in a while, and normal skin will repair the damage every once in a while without causing harm to the skin. But if the skin itself is fragile, the skin is thin, the resistance to the outside world is weak, there is red blood, or there are tiny wounds. If the skin is impacted by high-speed and high-pressure airflow again, it will be unbearable and serious problems may occur.

Therefore, the skin is sensitive and fragile, the cuticle is thin and red, and the skin that has been engaged in medical beauty projects for a short time is not suitable for "needle-free water-light needle".

To sum up, "needle-free water-light needle" is an entry-level medical beauty project, which can increase skin luster in a short time and make skin tender, full and elastic. But this effect won't last long, and you need to inject it every once in a while. With the increase of injection times, the effect will decrease. Sensitive and fragile skin is not suitable for "needle-free water light needle"?
