- FAST WRINKLE REDUCING POWER - Wrinkle reduction with just 1 tube. Retinaldehyde works up to 11 times faster than classic retinol.
- RADIANT, YOUTHFUL SKIN - Delivers remarkable visible improvement in texture, brightness, firmness & clarity. Vitamin A is a key pillar of Medik8's simple yet effective anti-ageing strategy of using vitamin C followed by sunscreen by day, and vitamin A at night. This is called the CSA philosophy.
