The Milk Makeup Holographic Stick (£24) is one of the brand's most popular products in the States, beloved for its easy-to-use, brush-free applicator, vegan formula, and holographic shade range. While they may look lavender (Supernova), pink (Stardust), or peach (Mars) in the tube, once they go on skin, the cream luminizers create a multifaceted, otherworldly glow that changes colour and opacity depending on how the light hits it.
