The reason Crystal Retinal is SO effective is that it was formulated with stabilised retinal, a potent derivative of vitamin A with next-generation anti-ageing results. Crystal Retinal delivers results comparable to clinical-grade vitamin A up to 11 times faster than classic retinol forms.

This overnight serum visibly minimises fine lines and wrinkles in just four weeks; firming and plumping the complexion to resurface skin texture and soften the face. Crystal Retinal also has an antibacterial effect on the skin, so it is perfect for breakout-prone skins.

Up until recently, there have been four strengths of Vitamin A:

Crystal Retinal 1 (0.01%) – An entry-level gentle-strength vitamin A, ideal for those who have really sensitive skin or are looking to incorporate a low strength but highly effective vitamin A serum in their routine.
Crystal Retinal 3 (0.03%) – The entry point for those new to vitamin A or have tried mild retinol formulas and the answer to those looking to prevent early signs of skin ageing.
Crystal Retinal 6 (0.06%) – Perfect for those who want to upgrade their high-strength retinol results.
Crystal Retinal 10 (0.10%) – A high-performance anti-aging serum for those looking to boost the results of Crystal Retinal 6.
Crystal Retinal is the ‘everyone’ Vitamin A, it has become a cult-favourite and has helped Medik8 carve their way to become a market leader in Vitamin A.

Medik8 are now extending the Crystal Retinal ladder for those comfortable on Crystal Retinal 10 and looking for more intense results.
