Hyaluronic acid is a part of human tissue, which is very good for restoring skin elasticity and removing wrinkles. You can do it at Han Mei's house. His Bonida hyaluronic acid has a good wrinkle removing effect. My mother made it last time, and now her face is very smooth. Their family's eleven needles of Bonida hyaluronic acid are three for one, and the discount is still great. You can consult yourself.
