What is a foundation balm you might ask? Well, in the case of the Kevyn Aucoin Foundation Balm (£42), it's a rich, skin-loving balm that's packed with enough pigment to give you a full-level of coverage (think bye-bye redness and dark circles) when applied with a brush. Available in 20 shades that align with the brand's classic Etherealist Skin Illuminating Foundation (we'd love to see that number grow in the future), the balm is formulated with hyaluronic acid as well as avocado and olive oils, meaning it helps your skin stay soft and hydrated throughout the day. While people with oily-skin textures might want to steer clear of this base product, anyone with dry or mature skin should definitely add this to their beauty wishlist.
