PLLA filler is a kind of poly-L-lactic acid dermal filler, which is an artificial but integrated with the human body and can be decomposed and absorbed, with good biocompatibility and degradability. Its principle of action is to stimulate collagen regeneration by injecting into the bottom layer of the skin, effectively and progressively improving sunken temples and cheeks, fine lines and wrinkles on the face, and facial fat atrophy or loss, naturally presenting a plump childlike skin.
Hyaluronic acid is an acidic mucopolysaccharide known as the ideal natural moisturizing factor (NMF), for example: 2% pure hyaluronic acid aqueous solution can firmly retain 98% moisture.
Hyaluronic acid is a multifunctional matrix, and hyaluronic acid (hyaluronic acid) HA is widely distributed in all parts of the human body. The skin also contains a lot of hyaluronic acid. It can improve skin nutrient metabolism, make the skin soft, smooth, wrinkle, increase elasticity, prevent aging, and is a good transdermal absorption promoter while moisturizing. When used in combination with other nutrients, it can have a more optimal effect of promoting nutrient absorption.
