"Nars Sheer Glow Foundation (£35.50) is one of the best foundations for dry and mature skin types, as it doesn't settle into any fine lines and is really hydrating to give luminosity to the skin," Gallagher says. She adds that dermatologist Dr Justine Hextall often tells her patients that if they're thinking about Botox, they might try the Nars Sheer Glow foundation first to see if it helps them with the concerns they want Botox to address. "That's how flattering it is!" Gallagher says.
