REYOUNGELfacial filler (No-animal cross-linked hyaluronic acid filler) has a highly favorable safety profile. It is composed of non-animal stabilized hyaluronic acid. Hyaluronic acid is a substance found naturally in the human body. REYOUNGELfacial filler (No-animal cross-linked hyaluronic acid filler) is fully biocompatible. There is limited risk of animal-based disease transmission or development of allergic reactions to animal proteins. No allergy testing is required before use. REYOUNGELfacial filler (No-animal cross-linked hyaluronic acid filler) maintains its shape using the body's own moisture. The hyaluronic acid in REYOUNGEL is hydrophilic or "water loving. " As hyaluronic acid gradually degrades, each molecule binds to more water and over time, the same volume can be maintained with less hyaluronic acid. This ability of hyaluronic acid to bind to water is what helps provide long-lasting results.Unlike rooster-derived hyaluronic acids and bovine collagen products, Reyoungel is free from animal proteins. This limits any risk of animal-based disease transmissions or development of allergic reactions to animal proteins. It can be usd for removing facial wrinkles, enhancing lips and shaping facial contours.PRODUCT ADVANTAGES: Long-lasting, but not permanent; Non-animal; Fast, safely and efficacy; Biodegradable; No skin test needed.
