Collagen, seaweed and the nutrients that reverse skin ageing – with Dr Craig Rose

We spend a fortune on what goes on our skin, but Liz has long believed that what goes in matters just as much, if not more. In this episode, she talks to Dr Craig Rose, marine biologist and founder of Doctor Seaweed, about the nutrients that midlife women are chronically short on, and what that deficiency is quietly doing to our skin, metabolism, and brains.
