Not only is manuka honey is high in antioxidants, but it also has antibacterial properties, both of which make it a popular ingredient in a lot of skin-care formulations. Case in point: it's the star ingredient in the new Seed to Skin The Manuka Nutri-Mask (£115). Made up of 55% manuka honey, as well as ferulic acid and hyaluronic acids and a long list of plant extracts, this multipurpose treatment helps hydrate, soothe, and brighten the skin. It may also be a good option for those with acneic skin, although we always recommend doing a patch test before you slather it all over your face.
