PRODUCT DETAILS

Hello, calm. This blue leave-on facial serum is made to be your first serum step, with cooling, soothing care for sensitive or heat-stressed skin.

Some routines call for a lighter touch. Here, that means a water-like, lightweight texture that absorbs quickly and leaves a refreshing finish. It is designed for the moments when heat has left your skin feeling sensitive.

Blue lotus extract and a Cica-Peptide Complex anchor the soothing side of the formula. Together, they are intended to support hydration, softness and the skin barrier, giving your routine a comfort-focused layer.

For peptide-focused care, the formula includes a 1% Copper Peptide Solution, with Dipeptide-15 and Copper Tripeptide-1 among its declared components. It is intended to offer peptide care for the appearance of wrinkles. The 1% applies to the overall solution, not to Copper Tripeptide-1 alone. The serum is also presented for skin concerned with signs of aging, pairing that focus with its fresh, lightweight feel.
