1. Injection of hyaluronic acid: hyaluronic acid is injected into the skin to replenish moisture and fill wrinkles and lacrimal glands. The price is about 2000 yuan to 4000 yuan, and the effect lasts for 6~8 months.

2. Autologous fat filling: extract adipose tissue from other parts of your body, inject it into the lacrimal groove, fill the lacrimal groove, and achieve slimming effect at the same time. The price ranges from 3000 yuan to 8000 yuan, and the effect can last for more than 10 years.

If you want to fill the lacrimal passage, I suggest you go to a professional and formal institution for consultation. And don't be greedy for cheap and choose unqualified institutions.
