About Environ

The Vitamin A Pioneer

Founded in 1990 by South African plastic surgeon Dr. Des Fernandes, Environ was among the first skincare brands to combine vitamin A with antioxidants in cosmetic formulas. Its philosophy is simple: healthy-looking skin depends on vitamin A, introduced gradually so skin can adjust and keep improving.

Discover icons like the Vita-Antioxidant AVST Moisturisers, Youth EssentiA serums and RAD Shield Mineral Sunscreen, and see why Environ is a staple in professional treatment rooms.

The Science

THE VITAMIN STEP-UP SYSTEM

Environ's step-up approach introduces vitamin A gradually, starting with lower concentrations and moving to higher strengths as skin becomes accustomed. Paired with antioxidants such as vitamin C, it helps skin look smoother, firmer and more radiant over time.

BEYOND THE BOTTLE

Environ also offers at-home tools, including the Cosmetic Roll-CIT and the DF Mobile device, designed to help skincare penetrate more effectively.
