Every day, the skin’s immune system is challenged by the exposome, an increasing threat to our skin health - Today, our immune system becomes the new hero.

Optimmunist™ is the ultimate immune booster that shields the skin with its delicately encapsulated diatom oil.

Diatoms are marine jewels that help us breath, known as unicellular photosynthetic algae, responsible for almost half of the oxygen production on earth. And now, diatoms can optimize skin’s immunity.

Optimmunist™ boosts the skin immune system, repairs and strengthens the skin barrier, soothes and reduces redness and itching - an excellent partner to prevent and care for sensitive skin.

Optimmunist™ strengthens the skin barrier and boosts the immune system against external aggressions by strongly upregulating the production of interferon gamma by more than 70%.

  • A novel and future-proof approach to superficial inflammatory dermatoses with solid long-term growth
  • Shields and repairs the skin barrier against all external aggressors.
  • Calms and soothes sensitized skin by repairing the barrier and boosting the immune system
  • Immediately calms reactive and damaged skin after just one application.
  • Increased comfort and hydration
