'I'm in my late 70s and have tried many anti-wrinkle creams - one ticks every box for efficacy'

Beauty buffs are raving about a two-in-one 'youth-rewinding' cream that is said to erase the visibility of fine lines and wrinkles, as well as revitalise tired and dull-looking skin. The specialist serum which contains 'strong' active ingredients has been hailed as 'worth every penny' by returning customers on their second or third bottles.

Medik8's r-Retinoate Day and Night Youth Activating Cream can be used both day and night for faster visible brightening, revitalising and smoothing results while remaining gentle on the skin. This luxurious serum is powered by Medik8-exclusive encapsulated retinyl retinoate, a derivative of vitamin A, which is proven to be eight times more powerful than standard retinol in delivering age-defying benefits, according to the brand.

The luxury serum normally retails for £229 at the Medik8 website, but can be bought for a lot less in the brand's huge summer sale, which ends on Thursday (August 1). The Medik8 summer sale sees its bestselling anti-ageing creams and serums slashed by 20% for a limited time - you can shop everything in the sale here.
