Medik8 Crystal Retinal 24

Medik8 Crystal Retinal 24 is the top of Medik8's retinal ladder: a 0.24% retinaldehyde night serum, the brand's highest concentration to date, made for expert vitamin A users who have completed Crystal Retinal 20 and want the most their skin can take. Crystal Retinal is the No.1 retinal serum worldwide, and every strength shares the same patented stability system, so the retinal stays potent until the last pump.

Retinaldehyde is the form of vitamin A one step closer to retinoic acid than retinol, which is why it works up to 11 times faster. At 0.24%, Medik8 Crystal Retinal 24 targets the appearance of fine lines and wrinkles, dark spots, uneven texture and loss of firmness, while hyaluronic acid, glycerin and squalane keep skin comfortable and vitamin E adds antioxidant support. Medik8 reports visible improvement in wrinkles, smoothness and brightness in as little as 7 days, and the range's clinical study on Crystal Retinal 6 found a 20% reduction in the appearance of wrinkles over 12 weeks.
