Hyaluronic Acid

When applied topically, hyaluronic acid is safe and particularly well-tolerated by all skin types. It is rather in aesthetic medicine, where hyaluronic acid is used as a filler for wrinkles through injections, that redness and irritation may occur.

Hyaluronic acid is an indispensable active ingredient in cosmetics, prized for its ability to plump the skin and reduce the signs of ageing. It appears in various forms ("Sodium Hyaluronate", "Sodium Acetylated Hyaluronate", etc.), so much so that distinguishing between them can be challenging. What differences exist among these compounds? Let us take stock.

Hyaluronic acid and polyglutamic acid are two biopolymers often compared, recognised in skincare for their excellent moisturising properties. However, they differ in certain aspects, 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 moisturising and anti-ageing properties.

Which forms should be used?
