'I'm in my late 50s and have tried many anti-wrinkle treatments - one's tricked my friends into thinking I've had work done'

Science-backed skincare giant Medik8 is most famously known for products like its Crystal Retinal, which is backed by doctors and dermatologists for rapid anti-ageing results on fine lines and wrinkles, as well as its Liquid Peptides, which promise to give visible results in seven days. But shoppers have now found a new jewel in the Medik8 crown, which they say, works its magic overnight so 'wrinkles are gone in the morning.

Sleep Glycolic is one of Medik8's lesser known products, but those who have tried it have been astounded by the results. At £39, it's cheaper than some of Medik8's other offerings, and a good option for those looking for an easy to use product that doesn't need to be applied every day.

Sleep Glycolic is an at-home AHA (alpha hydroxy acid) peel treatment that delivers fast results overnight, without the usual redness and irritation associated with peel formulas. The leave-on treatment harnesses the power of 10% active glycolic acid to transform the look of dull, uneven and congested complexions.
