Not An Allergen

Kombucha

In its original, basic form, this powerhouse probiotic made with fermented green or black tea with sugar, bacteria, and yeast is not a top contact allergen. However, be wary of mass produced, pre-packaged kombucha that might also contain artificial flavors (many of which are contact allergens and/or related to fragrance) or food dyes. People who have patch tested positive to lemon and other fruits that are popular additions to kombucha sometimes find that any contact with the fruits can cause a rash on the lips or around the mouth. Remember that food allergies and contact skin allergies operate differently, however, so get a patch test from your dermatologist and check with your allergist before deciding if kombucha (and which) is right for you.

Research into the human microbome is still in its infancy but there are some suggestions that promoting our natural, healthy bacteria could help us fight off infection. This could be important for atopic dermatitis (eczema) and other skins with barrier damage due to topical steroids which thin the skin, or from the environmental pollutants, poor diet, or even psychological stress (studies show that stress disrupts the barrier and its ability to heal itself). When the skin’s barrier is compromised it tends to be colonized by harmful bacteria. Some studies on probiotics for children with atopic dermatitis (check out this helpful summary from the National Eczema Association) showed promising results, but as always, check with your dermatologist before trying anything new for your skin. More research is required to measure efficacy as well as to identify the correct strains and doses, and to determine possible risks.

If you have a history of sensitive skin, don’t guess: random trial and error can cause more damage. Ask your dermatologist about a patch test.

Regularly published reports on the most common allergens by the North American Contact Dermatitis Group and European Surveillance System on Contact Allergies (based on over 28,000 patch test results, combined), plus other studies. Remember, we are all individuals — just because an ingredient is not on the most common allergen lists does not mean you cannot be sensitive to it, or that it will not become an allergen. These references, being based on so many patch test results, are a good basis but it is always best to get a patch test yourself.
