What Histidine is & what it does

An amino acid with humectant and antioxidant properties that hydrates and helps protect skin. It conditions and supports a smooth surface.

What does Histidine do in skincare?

Histidine is an amino acid used as a skin-conditioning ingredient, often as part of an amino-acid blend that supports the skin's surface. As an amino acid it is water-soluble and suits lightweight, hydrating formulas. Its role is supportive rather than a primary active.

Is Histidine safe?

Histidine is a naturally occurring amino acid and is generally regarded as well tolerated in cosmetic use. As with any ingredient, individual sensitivity is possible, so patch testing a new product is reasonable. This is general information and not medical advice.

Is Histidine vegan?

Histidine can be vegan, since it is commonly produced by fermentation or synthesis from non-animal sources. However, amino acids can also be sourced from animal proteins depending on the supplier. Check with the brand if vegan sourcing matters to you.
