Can I use vitamin C and niacinamide together?

Yes. They share this one bottle, so there is nothing to mix or time. If your skin tingles at first, use it every other day for two weeks, then daily as your skin allows.

Is it okay for sensitive skin?

It is made with ethyl ascorbic acid, a stabilised vitamin C, and no synthetic fragrance. It also holds citrus extracts, so patch test on your inner arm for 24 hours before you begin.

Where does it go with oils and the Kalahari serum?

Water-based first. Vitamin C serum, then the Royal Kalahari Face Serum or a face oil such as Marula, then moisturizer. The oil seals the serum in.

The creation

A fresh water serum with vitamin C and niacinamide.

It looks like water and feels like a cool drink for your skin. This is a light, fast-absorbing serum that sinks in without stickiness and leaves your face looking fresh, smooth and lit from within.

Two ideas sit at its centre. Ethyl ascorbic acid, a stabilised form of vitamin C, helps skin look brighter and more even. Niacinamide, a form of vitamin B3, helps tone look balanced and texture look refined. Around them we wrapped aloe and cucumber for cooling, light hydration, sodium hyaluronate to help skin hold moisture, and a blend of bilberry, sugar cane, maple, orange and lemon extracts for a fresh, soft feel.

Press three or four drops into clean skin, wait a moment, and follow with moisturizer or a face oil. It suits normal, combination and sensitive skin. Use it in the morning with sunscreen, or in the evening. Keep it away from retinol and benzoyl peroxide in the same routine.

The story behind

Made by hand, in small batches, by a mother and son in Brooklyn

Marianella spent her childhood in her grandmother's kitchen in Venezuela, making soap and beauty products by hand, and she still makes our serums the same way: by hand, in Williamsburg, Brooklyn, in batches of 50 to 100.

This one began with a simple wish: a vitamin C that feels like water on the skin, not like a chemistry project. She paired a stabilised vitamin C with niacinamide, then added aloe, cucumber and fruit extracts, so brightening comes with comfort. Her son David brings the design. No harsh chemicals, no animal testing, and as little waste as we can manage.

The perfect partner

Vitamin C Collagen Boosting Face Serum with Niacinamide

Vitamin C serum first, being water-based; the Kalahari oils press over it to seal it in.

Mist first, then the serum on damp skin; water-based layers go before any oil.

Serum first, then 4–6 drops of ultra-light squalane to hold moisture in.

Serum on face and neck, away from the eyes; the roller then covers the eye area and lips.
