PEG-8 Hyaluronate

PEG-8 Hyaluronate is a chemically modified version of hyaluronic acid (HA), one of skin's natural humectants. The modification involves attaching polyethylene glycol (PEG) chains to the hyaluronic acid molecule. This alteration is intended to improve how the ingredient penetrates the skin compared to standard hyaluronic acid, which is a large molecule that typically sits on the skin surface.In formulations, PEG-8 Hyaluronate functions as an emollient and skin conditioner, helping to draw moisture into the skin and maintain hydration levels. It is commonly used in serums, moisturisers and tr…

PEG-8 Hyaluronate works as a humectant, meaning it binds water molecules and draws them towards the skin. The polyethylene glycol modification reduces the molecule's size, which theoretically allows it to penetrate more effectively into the upper layers of the epidermis compared to standard hyaluronic acid.Once in the skin, it helps maintain hydration by binding moisture, which can support skin plumpness and overall texture. The mechanism is similar to unmodified HA, but with potentially better bioavailability due to the structural change.

PEG-8 Hyaluronate is most effective when applied to damp skin, as this helps the humectant draw moisture into the epidermis. It works well in serums and can be layered under occlusive moisturisers to seal in hydration. There is no upper limit on daily use, though it is typically found in products used once or twice daily.

PEG-8 Hyaluronate is generally well-tolerated and considered safe for use in cosmetics. It is suitable for most skin types, including sensitive skin, though as with any ingredient, patch testing is advisable if you have known sensitivities to PEG-based compounds.
