About this ingredient
Thermus thermophilus ferment is a product of fermentation by Thermus thermophilus, a bacterium that grows at high temperatures. The INCI name is spelled with a double "l": Thermus Thermophillus Ferment. Information on where the strain for the cosmetic raw material was isolated comes only from the manufacturer. The manufacturer describes the ferment as a protective antioxidant with heat-stable enzymes and says it shields keratinocyte mitochondria from UV and infrared damage. None of this has been published in peer-reviewed form. No independent analysis of the ferment's composition exists. The ingredient is added to sunscreens, after-sun products and anti-aging creams. There are no published studies of this ingredient in humans, animals or cell cultures. PubMed and Crossref have no records on it. The only data are the manufacturer's own unreviewed materials. Papers on other T. thermophilus ferments do exist: a mixed culture with Bacillus subtilis and a co-ferment with ectoin, both from cosmetic companies' R&D teams. These are different ingredients, and their results do not apply here. There are no published data on irritation, allergy or absorption through the skin, and no reported adverse reactions. There are no data on use during pregnancy or breastfeeding.
