Unlock the secret behind glass-like skin with the Medik8 Crystal Retinal 6.

This vitamin-A-infused serum arrives in a series of progressive strengths that allow you to personalise your anti-ageing skin care routine.

Retinaldehyde is the key ingredient within Crystal Retinal. This next-gen form of vitamin A has been proven to deliver results up to 11x quicker than regular retinol. With consistent use, skin can appear visibly brighter, firmer, and smoother.

Encapsulated retinaldehyde, hyaluronic acid, ​vitamin E and glycerin join forces to protect and perfect the skin, allowing it to look and feel noticeably healthier.

The brand's double-layered stabilisation system combines crystal-encapsulation with a patent-pending carrot seed oil complex that surrounds and protects the retinal molecule. The result? Long-lasting, consistent effectiveness that encourages the skin to thrive.

In addition, an innovative crystal encapsulation slowly breaks down on the skin to drip feed retinal into the skin overnight.
