Her final tip? To look after your mental wellbeing. “It’s about stress levels,” says Dr Rossi. “We spoke briefly about both the gut-brain and gut-skin axis but there’s also a triad axis between the brain, gut and skin, so if we’re stressed, that can start to play out on our skin, as well as in the gut. So I advise doing 10 minutes of mindfulness or going for a relaxing walk each day.”
