The immuno-modulator for indoor pollution control

Edition Date :
April 29, 2022

Eosidin is the first product targeting specifically indoor pollution and tackling skin immuno-modulation to avoid atopic-prone skin condition and hypersensitivity.

It is a natural active ingredient extracted from green citrus unshiu originated from Jeju island in Korea, a UNESCO heritage protected island. Citrus unshiu is rich in synephrine and hesperidin, highly potent molecules that play a major role in regulating the eotaxin synthesis process, responsible for histamine release.

Eosidin already won 3 prizes from the cosmetics industry, recognizing its innovative mechanism of action and sustainable sourcing:

  • Silver prize at the Itehpec Innovation Award at in-cosmetics 2017.
  • Winner at Sustainable Beauty Awards 2018 in the category "Sustainable Ingredient "
  • Winner in the category "anti-pollution" at the Ringier Technology Innovation Awards 2019 - Personal Care Industry
