I heard that many stars are using this beauty. According to the brochure of Chengdu Beauty and Plastic Surgery Hospital, hyaluronic acid is a colloidal substance, which exists in a large number of connective tissues and dermis of human body. It has many functions such as wrinkle removal, hydration, skin rejuvenation and shaping. It can quickly provide moisture for deep skin and solve the problem of dry wrinkles and relaxation of face and neck skin. Can eliminate facial static wrinkles, including eye fine lines, crow's feet, decree lines, etc. It can also be used to enrich the lips, modify the lip shape, modify the chin, increase the nose shape, transform the nose shape, enrich the cheeks, fill the facial depression and so on. It seems that the effect is really good. No wonder stars don't look old.
