28Extremoin® is a patented anti-pollution active with global and clinically proven efficacy. The natural, multifunctional “urban protection” ingredient has been developed to manage the challenging conditions facing our skin in modern life. 28Extremoin® is a mix of two pure and natural stress protection molecules: Ectoin® and Hydroxyectoin. The thermal protection benefits of Hydroxyectoin complete the proven cell protection properties of Ectoin® that defend the skin against pollution, inflammation and visible aging.

28Extremoin® has a unique two-step anti-pollution efficacy:

  1. protection and prevention
  2. repair and regeneration

In contrast to anti-oxidants, 28Extremoin® acts before damage occurs by safeguarding skin cells from particle induced damage. Furthermore, its skin repairing mechanism ensures visible relief from the stresses of pollution. This comprehensive anti-pollution activity helps to protect the skin from particle induced skin irritations, wrinkle formation and pigmentation.

Proven efficacy

  • Particulate matter protection (PM10, PM2.5, PM1, PAHs, heavy metals)
  • Ultra-fine particle protection (UP/PM0.1/nanosize)
  • Airborne allergen protection
  • IR-A & visible/blue light, UVA/UVB protection
  • Inflammation reduction / anti-irritant
  • anti-aging

28Extremoin® is a mix of two natural stress-protection molecules: Ectoin® and Hydroxyectoin, or so called "extremolytes". Extremolytes are produced inside of highly specialised plants and microorganisms which thrive in the harshest conditions one can imagine. They prosper in salt lakes, hot springs, the deep sea, arctic ice or deserts and resist extreme temperatures, total drought, high salinity or unbearable UV-radiation – thanks to their little safe-guards. The components of 28Extremoin® are both accumulated in salt and temperature tolerant microorganisms like Halomonas elongata.

We manufacture both actives exclusively at our German plant with a patented and GMO-free bio fermentation process according to EN ISO 13485.
