1 DEEP WRINKLES

Laughter lines, crow’s feet – whatever you call them, lines around the eyes are an inevitable by-product of expressing emotion (can you stop blinking for a few seconds?). When lines become deep-etched wrinkles, though, they can affect skin texture, so it becomes harder to apply make-up. Retinol is clinically proven to reduce their appearance, and it can be found in Olay Eyes Pro-Retinol Eye Treatment, £29.99, which, unlike most retinol products, is gentle enough to use during the day.
