PRODUCT DETAILS

This two-phase oil-and-water ampoule brings hydration and soothing care together. It helps deeply hydrate while reducing the look of redness and irritation, making it a thoughtful choice when your skin needs moisture and calm.

The bi-phase formula helps balance oil and moisture. Its lightweight, smooth-absorbing finish feels non-greasy and non-sticky, so the nourishing oil-and-water format doesn’t have to feel heavy on your skin.

CICA-GO Complex and arbutin help brighten the appearance of dark spots and overall skin tone. The formula also includes squalane and panthenol, which are highlighted for helping care for a compromised protective barrier while maintaining oil-and-moisture balance.

The ampoule is listed for all skin types, including sensitive and combination skin. Its stated fit also extends to sensitive skin that leans oily or dry, offering broad support without losing sight of the concerns that can make skin feel out of balance.
