How to apply

Press the dropper and release 2-3 drops in the palm of your hand, on your finger tips or directly on a cleansed face and neck. To ensure optimal hygiene, the dropper should never make contact with your face or hands. Gently massage or pat the liquid into your skin. Wait for the serum to fully absorb and follow with a moisturizer to lock all the good stuff in.


A waterweight, transparent fluid that absorbs quickly into the skin.
