Hydraulic acupuncture must be carried out according to the course of treatment. At least one course of treatment is required, that is, more than three times. The effects of water-light injections can be superimposed. The more times you apply them, the better the effect will be and the longer it will last. After that, if possible, apply it once every three months or six months. The more you apply it, the more supple and translucent your skin will be. Hydra injection is not micro plastic surgery, it is skin management and a high-end skin care product.
