Although hyaluronic acid and Tong Yan Zhen are both functional fillers, their principles are quite different. Hyaluronic acid is used as a physical filler to fill the depression, while children's eye acupuncture stimulates the production of collagen in deep skin and stimulates cell vitality at the same time. The former has immediate postoperative effect, but the duration is short, and it needs to be supplemented every 4-6 months. In the last two weeks, collagen began to increase, and the effect was gradually reflected, which was more real and lasting. At the same time, children's eye acupuncture improves and tightens the whole facial skin.
