Benefits of Histidine

A well-tolerated, naturally occurring ingredient that supports skin comfort and moisture.

• Natural Moisturizing Factor: A component of skin’s own NMF that helps bind and retain moisture.
• Skin Conditioning: Leaves skin feeling soft, smooth and supple.
• Antioxidant Support: Its imidazole ring can help bind reactive metal ions and buffer oxidative stress at the surface.
• Lightweight Humectant: Water-soluble and easy to work into water-based formulas.
• Well Tolerated: Gentle and broadly compatible, suitable for most skin types.

How It Works

Histidine is a small, water-soluble molecule that behaves as a humectant — attracting and holding water at the skin’s surface, much as it does within the skin’s native NMF. Beyond humectancy, its side chain can chelate trace metals and help soothe the look of stressed skin. Replenishing these amino acids topically helps support the look and feel of well-hydrated, comfortable skin.

Formulating with Histidine

Histidine is water-soluble and added to the water phase, typically at low levels as part of an NMF or amino-acid complex alongside humectants such as glycerin, sodium PCA and other amino acids. It is compatible across a broad pH range; observe good manufacturing and preservation practice.
