C-Tetra Intense


Reveal a more youthful appearance with lightweight Intelligent Retinol (vitamin A) serums. Designed to complement skin’s nightly regenerative cycle, the serum resurfaces while you sleep to rejuvenate skin and restore radiance. Hailed as the most effective ingredient in anti-ageing, vitamin A improves skin texture, minimises the appearance of fine lines and wrinkles and balances uneven skin tone. 

Formulated with three different strengths of retinol, with each formulation containing vitamin E for enhanced stability:

  • Retinol 3TR (0.3% retinol) - Perfect for those new to vitamin A, or as an upgrade from Night Ritual Vitamin A. 
  • Retinol 6TR (0.6% retinol) - Perfect for those who have already been using retinol in their regime and are looking for a higher strength. 
  • Retinol 10TR (1% retinol) - Highest strength retinol is ideal for those who have used retinol regularly in their regime. 

Go Intense - The Intense upgrades of the Retinol serums have been supercharged with ingredients designed to boost the anti-ageing benefits of vitamin A without increasing irritation and for deep hydration.
