What it is
Thermus Thermophillus Ferment is produced by culturing Thermus thermophilus, a thermophilic bacterium originally isolated from hot environments, and collecting the resulting ferment. In skincare and sunscreens it is used as a skin-conditioning agent and is marketed for the antioxidant and protective enzymes associated with heat-adapted microorganisms. It is typically incorporated at low levels in the water phase.
Safety & warnings
Bacterial ferment ingredients are generally well tolerated at the low concentrations used in cosmetics, though, as with any biologically derived material, occasional sensitivity is possible in predisposed individuals.
Origin & sourcing
Biotechnological; obtained by fermentation of the thermophilic bacterium Thermus thermophilus and processing of the resulting culture.
