TetCode4®
Bridging Nature
and Science

Four decades of dermatology in one formula

»After almost 40 years in dermatology, I know that skincare needs more than just attractive promises. It needs natural intelligence and scientific clarity. That's why I developed TetCode4® – a formula that combines the best of both worlds.«

Four wins

The secret
in interaction

TetCode4® is a sophisticated system consisting of four components:

  • Vitamine A, C, E – proven classics for protection
    and regeneration
  • Niacin (B3) – strengthens the skin's barrier and immune system
  • Botanicals – selected plant power
  • Biomimetics – molecules modelled on nature

Modular and precise
Each active ingredient works where and when it is needed. The components complement each other: cleansing, nourishing, protecting – and improving the skin structure in the long term.

The Goal
The goal is skin that stays healthy, retains its natural radiance and feels strong every day.
