THE EYE-WRINKLE REDUCER UMA Absolute Anti-Aging Eye Oil, £60

Oils make for a great moisture top-up, so one just for thirsty eyes is a no-brainer. Combining rose to rehydrate and eucalyptus to combat puffiness, it’s not cheap – but a single drop will cover under, over and around the eyes. Stick to an evening application to avoid panda eyes, though.
