When applied topically, hyaluronic acid is safe and particularly well-tolerated by all skin types. It's more so in aesthetic medicine where hyaluronic acid is used as an injectable filler for wrinkles, that redness and irritation can occur.

Hyaluronic acid is an essential active ingredient in cosmetics, prized for its ability to plump the skin and diminish visible signs of aging. It comes in various forms ("Sodium Hyaluronate," "Sodium Acetylated Hyaluronate," etc.), making it hard to know which one is which. What differences exist among all these compounds? Let’s break it down.

Hyaluronic acid and polyglutamic acid are two biopolymers often compared, recognized in skincare for their excellent moisturizing properties. However, they diverge on certain points, particularly in their origin and chemical structure. Here are their differences.

Hyaluronic acid has been the star ingredient in cosmetic care in recent years, renowned for its excellent moisturizing and anti-aging properties.

Which forms should be used?
