What Kine-C does
Vivier lists three benefits: it helps smooth the appearance of fine lines and wrinkles, boosts radiance while improving the look of uneven skin tone, and refines texture for a smoother, more even-looking complexion. The brand describes it as a lightweight, oil-free multi-benefit antioxidant serum that addresses visible signs of aging and environmental damage.
Key ingredients
Vivier lists 10% vitamin C as L-ascorbic acid USP, plus two peptides. L-ascorbic acid is the form of vitamin C Vivier has built its range around since its first vitamin C serum in 2000.
Who it is for
Normal, combination and oily skin, which is Vivier’s own guidance for this one. If your skin is dry or mature, the brand points to C E Peptides or QuintiSerum instead, both of which sit in the same antioxidant family at higher vitamin C percentages.
How to use it
Two to three drops in the palm, then a thin layer over face, neck, chest and the backs of the hands. Vivier says once or twice daily on clean, dry skin. Vitamin C in the morning under sunscreen is the routine most of our patients settle into.
How it fits with your treatments at Bar Beauty
An antioxidant serum is the everyday half of skin health, and the in-clinic work is the other half. We time vitamin C reintroduction around resurfacing treatments rather than assuming you can go straight back to it.
Buying Vivier in Toronto
Buying vitamin C from an authorized retailer matters more than it does for most categories, because L-ascorbic acid degrades with age and poor storage. We buy through Vivier Pharma’s professional channel, so stock is genuine, in date and handled properly.
