Lactobacillus/Punica Granatum Fruit Ferment Extract

This is a fermented pomegranate extract used mainly for antioxidant/skin-conditioning and microbiome-support claims, typically at low concentrations (often <1–3%). While generally well tolerated, botanical ferment mixtures can contain residual organic acids and diverse fermentation byproducts that occasionally sting compromised barriers or trigger low-rate contact reactions in very reactive/eczema-prone patients. Given the variability between batches and the higher reactivity risk of complex botanicals versus single-molecule humectants, I rate it as gentle but not exceptionally gentle. Safety Notes: In commercial skincare, Lactobacillus/Punica Granatum Fruit Ferment Extract is most often used as a probiotic/ferment “active” or skin-conditioning adjunct at very low levels (~0.01–0.1%) in mass-market toners, cleansers, and creams where it functions mainly as a label-claim/support ingredient. Higher concentrations are seen in consumer-available “ferment essence/serum” style leave-on products and concentrated ampoules, where total ferment extract can reach ~1–5% depending on supplier activity, odor/color tolerance, and stability/preservative system; rinse-off formats typically sit toward the lower end due to cost and limited contact time.
