LACTOBACILLUS/HIBISCUS ACETOSELLA LEAF/SUCROSE FERMENT EXTRACT FILTRATE.

The ingredient's multifaceted action is rooted in its fermented components. Lactobacillus ferments are known for their ability to contribute antimicrobial properties, helping to balance the skin's microflora, alongside antioxidant capabilities to combat oxidative stress, and humectant effects to preserve skin moisture. The Hibiscus acetosella leaf extract itself is rich in phenolic compounds, such as caffeic acid, which further enhance its antioxidant and antibacterial activities. The fermentation process optimally enhances the bioavailability of these beneficial compounds and may generate novel active constituents. While certain Lactobacillus ferments have demonstrated tyrosinase inhibition, potentially leading to a skin lightening effect, this ingredient's primary benefits are centered on antioxidant protection, microbial balance, and hydration.
