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

how to use

Dispense 3-4 drops into your hands and gently press into a clean face and neck in the morning. Follow up with your preferred moisturizer and an SPF.

who it's for

A breakthrough for sensitive skin that cannot tolerate standard highly-acidic Vitamin C. It imparts an instant, healthy glow and significantly smooths the skin canvas over time.

cautions & pairing

The clever inclusion of Salicylic Acid ensures that dead skin cells do not block the absorption of the Vitamin C, making every drop of the serum count towards visibly brighter skin.
