Crystal Retinal
Medik8 is the industry leader in stabilized retinaldehyde, which converts to retinoic acid 11x faster than standard retinol. Their crystal encapsulation technology ensures potency and a time-release delivery that minimizes the irritation typically associated with high-strength retinoids.
Quality & Materials
Features encapsulated retinaldehyde at varying strengths (0.01% to 0.2%). Includes hyaluronic acid, glycerin, and vitamin E for barrier support.
Evidence & Testing
Medik8 conducts extensive independent clinical trials. Their data shows significant improvements in wrinkle depth and skin texture in as little as 4 weeks.
Brand Transparency
Medik8 is highly transparent about their ladder system and concentrations. They manufacture in their own ISO-certified labs in the UK.
Value Assessment
$54-$106 depending on strength. While expensive, the efficacy of retinaldehyde means you need less product to see superior results compared to cheap retinol.
Why Not Alternatives?
Unlike The Ordinary or Inkey List, Medik8 uses a patented stabilization system that prevents the retinal from degrading before it hits your skin. Most competitors use cheaper retinol or unstable retinal that loses efficacy within weeks of opening.
