Do you really need gluten-free skin care?

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 is made up of molecules that are too big to be absorbed through the skin but, because research has linked wheat protein to increasing skin firmness and restructuring damaged hair follicles[ii], it is often added to cosmetics and skincare 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?

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?

The amount of gluten used in cosmetic formulations is so small that it is often thought that the ingredient poses little or no risk to people with a sensitivity or an allergy to gluten[iii].

Whilst the risk of a product causing an allergic reaction is minimal, there have been cases of people developing urticaria (an itchy rash commonly known as Hives) as a result of using products containing HWP.

In 2013, it was reported that a form of HWP used in a Japanese facial soap caused as many as 1,900[iv] people to experience allergic reactions and such incidences have led researchers to review the safety of the ingredient.

Research has since suggested that not only can some forms of HWP trigger allergic reactions in those with a previous history of gluten intolerance, but that it also has the potential to cause people with no medical history of an intolerance to react to dietary sources of wheat including wheat flour and wheat gluten.

Who is at risk of developing a reaction to products containing HWP?

Anyone can be at risk of an allergic reaction to HWP but diagnosed Coeliacs and those with a known sensitivity to gluten are perhaps most vulnerable.

There are also increasing concerns that people affected by Coeliac disease or gluten-intolerance can be vulnerable to gluten cross-reactivity. This is when antibodies, produced to help protect the body from gluten, react against proteins used in food and cosmetics that have a similar make-up to gluten.

For this reason, it is advised that people conduct a patch test before using products containing HWP and consult their GP if they do experience irritation[iii].

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.
