Why is gluten used in beauty products?
Gluten is a protein that is commonly found in foods containing wheat, barley or rye[i].
A potential allergen, it's made up of molecules that are too big to be absorbed through the skin. Because research has linked wheat protein to increasing skin firmness and restructuring damaged hair follicles[ii], it is often added to cosmetics and skin care products in the form of Hydrolysed Wheat Protein (HWP) but can also found under a variety of other names.
How can I tell if there is gluten in my skin care?
Unsure if your skin care contains gluten? Take care to read the label thoroughly as many commonly used skin care ingredients can be a source of gluten.
To be sure your product is actually gluten-free, check the label for the following sources of gluten.

What beauty products can contain hydrolysed wheat protein (HWP)?
HWP has smaller particles than gluten and this makes it easy to add into hair care and skin care formulas as well as water-based make-up products such as foundations and lipsticks.
Is it safe to use gluten in skin care and cosmetics?
Gluten itself is generally considered low risk when applied to the skin because the gluten protein molecules are too large to penetrate through healthy, intact skin. For most people, gluten in cosmetics does not trigger the same reactions as eating gluten.
However, concerns have been raised around hydrolysed wheat protein (HWP), a processed form of wheat protein sometimes used in skincare. In rare cases, HWP has been linked to allergic skin reactions such as urticaria (hives). A well-documented incident in Japan in 2013 saw around 1,900 people react to a facial soap containing a specific form of HWP. Research suggested that this type of HWP could even cause people with no prior gluten issues to later develop wheat allergies.
Who may be at risk?
People with coeliac disease or gluten sensitivity are more cautious, as even small topical exposures could, in theory, cause irritation or contribute to cross-reactivity.
Anyone can, in rare cases, develop an allergy to HWP.
Best practice
- A patch test is recommended before using products containing HWP.
- Those with coeliac disease or a known gluten sensitivity may prefer to avoid products containing gluten-derived ingredients altogether, to minimise any risk.
The benefits of Quinoa: an alternative to HWP
The good news is that there is a natural alternative to HWP. Green People researched extensively to find an ingredient that could replace WHP and use 100% natural Quinoa protein, that is grown specifically for use in cosmetics, in its place.
Gluten-free and packed with amino acids and vitamins E and B, Quinoa’s natural properties have been found to help protect the skin and repair damaged hair follicles. Oats are another possible alternative as they contain Avenin which, although closely resembling gluten, can be tolerated by many Coeliacs[v].
However, some Coeliacs may still react to Avenin and, as some oats can be processed in the same environment as gluten, many Coeliac prefer to avoid foods and cosmetic products that contain Avenin.
