  •    Results interpretation

Session:

  •    0.5 day
  •    5 trainees
  •    In your office or in our laboratory

Presentation of In Vitro test
  • Principle of solar protection
  • How to protect (Absorption – Scaterring)
  • Mecanisms involved and evaluation methods
Understand In Vitro test
  • In Vitro & In Vivo
  • Key parameters of In Vitro test (Appliances – Substrate – Calibration)
  • Traps to avoid for valid results (Methods – Products – Artefacts)
  • Why In Vitro test?
Methods
  • In Vivo / In Vitro correlation: Why? How? Limits?
  • Added value of methods (global protection – comparion)
Practice part
  • No treated in this module

Module 2 – Deepening

HeF001b – UV transmission and evaluating sun protection (Theory + Practice)

Goal:
