The brand beloved by dermatologists and beauty editors alike introduces the Medik8 Illuminating Eye Balm (£32) this month, which promises to both brighten and hydrate the delicate skin around your eyes. The formula contains cucumber, which, in addition to containing antioxidants, also helps soothe the skin, while red algae depuffs and glycerin and hyaluronic acid hydrate. It also contains a subtle, light-reflecting tint that helps to counteract dark circles.
