Stila Heaven's Hue Hydro-Luminator 15ml (Multiple Colours) — £16.80 (was £28) @ M&S

Stila Heaven's Hue is a jelly-textured luminator that gives skin that dewy, glass-skin glow without looking glittery. You can wear it alone, mix it into moisturiser or dab it on cheekbones for a soft highlight — and the vegan formula is infused with hibiscus, passionflower and squalane to hydrate as it brightens. M&S has 40% off across Champagne, Light Bronze and Rose Shine shades right now, which is a proper saving on a versatile cult highlighter.
