Ingredients

Panthenol, ceramides, and black soybean extract help deliver cushiony hydration with barrier support.

Ampoules are designed to deliver a higher concentration of moisture-supportive ingredients in a layer that sits between toner and cream. For dry or barrier-stressed skin, that middle step can make a noticeable difference because it adds hydration and cushioning before the final sealing product is applied. Panthenol is especially helpful in this kind of formula because it converts to provitamin B5 activity on the skin and is widely used to support softness, moisture retention, and visible barrier comfort.

Ceramides strengthen that barrier story by reinforcing the skin's lipid matrix, while black soybean extract adds a nourishing, conditioning angle. The product also highlights extended hydration, which fits with the idea of a formula designed to keep the skin feeling replenished beyond the first few minutes after application. In practice, this ampoule works best as a daily moisture-repair step for skin that feels dry, rough, or depleted and wants longer-lasting hydration with a softer, more elastic feel.
