Galactomyces
Interactions with Malassezia yeasts
Galactomyces is a type of yeast commonly used in cosmetics that has potential to influence skin conditions associated with Malassezia yeasts. Galactomyces is known to stimulate the Aryl Hydrocarbon Receptor (AhR), a protein that plays a role in how our skin reacts to certain substances. As studies have implicated Malassezia yeasts in diseased skin with excess AhR activity, individuals suffering from Malassezia-related diseases may benefit from avoiding additional AhR stimulants as a precautionary measure.
Rating: Highly reactive under certain conditions
Reactivity to products containing Galactomyces may depend on the condition of your skin and the duration of the product's use. While there is some uncertainty due to multiple influencing factors, there is a significant chance that Galactomyces will aggravate conditions associated with Malassezia yeasts. We strongly recommend avoiding products containing Galactomyces.
