Pseudozyma Epicola/Camellia Japonica Seed Oil Ferment Extract Filtrate

This is a fermented botanical/oil-derived filtrate primarily used at low concentrations as a conditioning/skin-feel and barrier-support ingredient; it is not an exfoliating acid or high-potency active. While camellia derivatives are generally well-tolerated, fermentation byproducts and residual yeast-related components can occasionally provoke stinging or dermatitis in highly reactive or eczema-prone individuals, so it is best classified as gentle rather than very gentle/inert. Safety Notes: In commercial skincare, this type of ferment filtrate is most often used as a minor supporting humectant/conditioning active in leave-on emulsions and essences, with low-end inclusion commonly around 0.01–0.1% (often consistent with supplier-recommended use levels for fermentation-derived extracts). High-strength consumer products that feature the ferment as a highlighted key ingredient (especially watery essences/serums and barrier-support formulas) can push into the 1–5% range, which is typically near the practical upper end before cost, odor/color, and preservation/stability constraints become limiting. It is less common in rinse-off products and generally appears at lower levels there because of short contact time.
