Smooth operator

It’s been a while since we’ve heard about the launch of a serum, so we’re excited about the latest Kiehl’s creation. This lightweight, easily absorbed and smoothing potion is designed to improve resilience, reduce fine lines and enhance radiance. That’s thanks to something they’re calling an adaptogenic herbal complex as well as hyaluronic acid with a molecule size that, they say, means it can help hydrate the upper layers of skin and improve barrier function.
