Powder hyaluronic acid. I got on a subscription and like the product but forgot to take it often enough and don’t want them to go bad - so you get it a a great price. What are the benefits of Infuse HA? Clinical studies have shown that daily use of HaPlex Plus (the key active ingredient in Infuse HA) increases skin moisture by 9% after only 45 days and increases skin elasticity by 11% after 180 days. HaPlex Plus studies have also confirmed the decrease of Superoxide Dismutase levels in the skin by 9% after 180 days, which prevents signs of aging such as fine lines and wrinkles. In the same study, HaPlex Plus decreased oxidative stress levels by 4% after 180 days (MDA down 4%). Oxidative stress is an imbalance of antioxidants in the body that can lead to cell and tissue damage. Infuse’s continued use works to hydrate and plump your skin while preventing the appearance of future fine lines and wrinkles.
