Holi (C) The Duo Calcium & Vitamin C - 0.5 oz

Formula Overview

Two-ingredient dry powder featuring calcium ketogluconate and sodium ascorbyl phosphate, designed to be activated by mixing with your liquid serum or essence at the moment of application.

A note from Evey

Vitamin C in skincare is a chemistry problem before it is a beauty problem. Most ascorbic acid serums lose potency within weeks of opening because the molecule oxidizes the moment it touches air, water, and light. This formula sidesteps that by keeping the C in dry powder form until you mix it.

What sets the duo apart is its short ingredient list. Just two: sodium ascorbyl phosphate, a gentle and stable C derivative that converts to active vitamin C on the skin, and calcium ketogluconate, a calcium salt studied for support of skin elasticity. No fillers, no emulsifiers, no oxidation clock running while it sits on your shelf.

I appreciate this kind of formulation because it reflects a live clean philosophy applied to a beauty active. Fewer ingredients done well, mixed fresh each application, with the chemistry working with you instead of against you.

A small scoop of powder mixed into your essence or moisturizer in the palm, then pressed into clean skin in the morning before sunscreen.
