Summary of the BIODERMA Symposium held during the Journées Dermatologiques de Paris 2025.

  • 🌓 Mastering Hyperpigmentation: Prof. Khaled Ezzedine details the mechanisms of post-inflammatory hyperpigmentation (PIH) and the essential role of tinted protection for diverse phototypes.
  • 🧴 Ecobiological Innovation: Karine Torrelli, PharmD, presents NAOS’s latest solutions designed to reinforce the skin’s natural defences rather than merely substituting them.
