Subject to rigorous medical testing, the Medik8 Crystal Retinal has earned the title of 'holy grail' product by shoppers.

'This is probably the most important part of my night routine now. I've started with 6 but will use 10 when that's finished,' wrote one user. 'I was using another retinoid before but this one seems much better and I'm beginning to notice little changes with my fine lines.'

Offering 0.01 per cent to 0.24 per cent retinaldehyde, there’s a strength for everyone, from very sensitive skins to expert users

Unlike retinol, which must first be converted to retinaldehyde and then to retinoic acid within the skin Crystal Retinal only requires one conversion to retinoic acid. This means it can deliver results comparable to clinical-grade vitamin A up to 11 times faster than classic forms of retinol. 

The result? Visibly minimised fine lines for a more youthful, more even-toned complexion.

And while fast-acting, the Medik8 Crystal Retinal is also kinder to the skin than most retinals thanks to the time-release stability system. Helping to ensure it's released slowly and steadily throughout the night, means it won’t overwhelm the skin.
