Formulated for very dry skin (and safe for those with eczema!), La Roche-Posay Lipikar Baume AP+M (£15) contains hard-working hydrating ingredients like shea butter, glycerin, and niacinamide, which help to soften your skin and soothe the itch. The rich balm also contains prebiotics to keep your skin's microbiome balanced and happy, which when it's not can make dryness even worse.
