how to use it

Everything you need for the best results, one step at a time.

how to use

Gently press the gel-like fluid into the face and neck using the palms of your hands. Follow immediately with a moisturizer to trap the hydration deep in the skin.

who it's for

A brilliant intervention for skin that looks exhausted. The dual molecular weights ensure the skin surface feels supple immediately, while the deeper layers hold onto hydration longer.

cautions & pairing

By drawing profound amounts of water into the epidermis, this serum smooths over the tiny, crepey lines that emerge when the skin lacks water, forcing a youthful bounce back to the surface.
