Kiehls vitamin c serum review

Designed by Meg O'Donnell.

That's right, vitamin C isn't just for staving off colds, and combined with the formula's two other hero ingredients – hydrating hyaluronic acid and glycerin – the concentrate is all about leaving skin smooth and glowing.

But how does it fare on different types of skin with various concerns? Four of the Refinery29 team gave the serum a try to find out exactly that. Read on to find out how we got on...

Very silicone heavy, feels more like a silicone primer not a serum or moisturiser. Puts a heavy coating on the skin so it sits on the skin surface and doesn't allow other serums can't penetrate....
