PRODUCT DETAILS

Hello, cool-down. When your skin feels warm or looks puffy, this water-blue ampoule gives immediate, gentle cooling. It has also been clinically tested for temporary facial de-puffing. Its lightweight essence gives your routine a refreshing pause without weighing your skin down.

The formula absorbs quickly and settles into a smooth, naturally dewy finish without stickiness or heaviness. Skin is left looking glossy and glass-like, with a fresh finish that feels easy to wear.

COOL-ing HA™ combines sodium hyaluronate with cooling actives for moisture support and a refreshing sensation, while glacier water adds another hydrating touch. The formula also contains five named peptides, including Acetyl Hexapeptide-8, which supports a firmer look and helps improve the appearance of enlarged or loose-looking pores. Together, these features support hydrated, smoother-looking skin with a glossy finish.
