Hyaluronic Acid Compound

A biotechnology-derived ferment filtrate made by fermenting hyaluronic acid with Lactococcus species, then filtering out the microorganisms. It is used primarily as a humectant/skin-conditioning ingredient to support hydration and product feel. COSMILE Europe lists it as a humectant derived from biotechnology.

Risks & Warnings

Generally low risk. Main concern is possible individual sensitivity to fermentation-derived materials or the finished formula, rather than a known inherent hazard. As with any leave-on hydrating ingredient, irritation is uncommon but patch testing is prudent for very reactive skin.
