Hydrolyzed Wheat Gluten

Hydrolyzed wheat gluten is a protein derived from wheat that has been broken down into smaller fragments through hydrolysis. This process reduces the molecular size of the protein, making it suitable for topical skincare use. It functions as both a moisturising and conditioning agent.In formulations, it works to attract and bind water to the skin's surface, helping to improve hydration. It also forms a protective layer that supports the skin barrier and can enhance the texture and feel of products.

Hydrolyzed wheat gluten is a humectant, meaning it has a natural affinity for water molecules. When applied to skin, it absorbs moisture from both the environment and deeper skin layers, drawing it toward the surface where it plumps fine lines and improves overall hydration.The protein fragments also sit on the skin's surface, forming a light protective film. This layer helps reduce transepidermal water loss (the evaporation of water from skin) and can support the skin barrier's natural repair processes.

Hydrolyzed wheat gluten works well in serums, moisturisers and hydrating essences. It layers effectively with other ingredients and can be used alongside actives like niacinamide or hyaluronic acid. For best results, apply to damp skin to maximise its hydrating effect, or use within a formula that contains complementary humectants.

Generally well-tolerated across most skin types. Those with a wheat allergy should patch test first, though properly hydrolyzed forms used in cosmetics are formulated to avoid triggering reactions.
