kombucha and panthenol

Panthenol converts to pantothenic acid (vitamin B5) inside the skin, where it plays a role in coenzyme A synthesis, essential for skin barrier repair. It hydrates not by sitting on the surface, but by integrating into the lipid bilayer and attracting water molecules from deeper layers. In this ampoule, Panthenol (Vitamin B5) targets dehydration, delivering delivers deep, lasting hydration that keeps skin plump throughout the day with consistent use.

Ingredients

Jeju kombucha and panthenol in a hydrating barrier-support ampoule.

Kombu Barrier Ampoule is built around hydration, antioxidant support, and barrier comfort. Its standout concentration of Jeju-produced kombucha is important because fermented tea ingredients are often valued for their antioxidant profile and their ability to support tired-looking skin with a fresher, more revived appearance. In a serum format, that antioxidant story is paired with water-binding hydration so the skin can look smoother and less depleted. Panthenol adds another practical benefit: it is widely used in skincare because it helps support skin comfort and reinforces a healthier-feeling moisture barrier, especially when the complexion is feeling dry or stressed. Together, these elements make sense for skin that needs both replenishment and visible calming. The ampoule texture also matters because lighter serum systems can deliver these actives without the weight of a heavy cream, which helps the skin feel hydrated rather than coated. The science behind the formula is therefore straightforward and credible: fermented antioxidant support, humectant hydration, and barrier-soothing care working together to improve softness, resilience, and the look of smoother skin.
