FSS Water Kefir PHA

Akin to AHAs and BHAs, PHAs (Polyhydroxy Acids) represent the next generation of exfoliants—designed to be gentler, making them suitable for sensitive skin. Traditional hydroxy acids often penetrate deeply, leading to irritation or dryness. PHAs like gluconic acid, however, work exclusively at the skin’s surface, removing dead cells and dull buildup while minimizing irritation.

FSS Water Kefir PHA delivers a vegan source of gluconic acid derived from fermented water kefir grains harvested from the prickly pear cactus. Through symbiotic fermentation with bacteria and yeast, water kefir is transformed into a nutrient-rich extract abundant in antioxidants and beneficial organic acids. This fermentation technology not only enhances cosmetic efficacy but also resonates with modern consumer values of eco-ethics and vegan provenance.

Clinically, gluconic acid encourages cellular renewal, dissolving the intercellular “glue” that binds dead cells to the skin’s surface. By accelerating exfoliation and stimulating collagen synthesis, FSS Water Kefir PHA supports smoother texture, brighter complexion, and improved barrier function. With proven collagen synthesis activation and non-cytotoxicity at standard concentrations, this ingredient delivers safe, effective exfoliation while revitalizing the skin.
