Phytokeratin: Are there dangers we should be aware of?

A plant-based alternative to animal keratin, the phytokeratin can be described as a sequence of amino acids derived from plant proteins, often sourced from grains such as wheat, corn, or soy. These amino acids are quite similar to those of human keratin, a fibrous protein found in the outermost layers of the epidermis, but also in hair and nails. The phytokeratin is valued in cosmetics for its moisturising and strengthening properties and is included in the composition of many treatments under the INCI names "Hydrolyzed Wheat Protein" or "Hydrolyzed Sweet Almond Protein". It is also appreciated for its safety.

Phytokeratin is a cosmetic active ingredient that is very well tolerated by all skin types, even the most sensitive ones.

Highly biocompatible with skin and hair, phytokeratin is not associated with risks of irritation or allergy. Indeed, to date, no skin reactions have been reported in the scientific literature. Suitable for sensitive skin, phytokeratin does not present any particular incompatibility with other cosmetic actives. It should also be noted that no risk has been identified regarding the use of cosmetics containing phytokeratin in pregnant or breastfeeding women. It is also interesting to know that phytokeratin is generally found at a level of 0.5 to 5% in formulation, although the European cosmetic regulation does not state a maximum concentration.
