Osmotic gel is a complex made of two ingredients: oleanolic acid, extracted from the leaves of the olive tree, and NDGA, the nordihydroguaiaretic acid.
The synergistic action of the two ingredients allows to fight acne on all fronts. Oleanolic acid inhibits 5-alpha-reductase, thus reducing sebum hypersecretion; nordihydroguaiaretic acid regulates cell growth, inhibiting hyperkeratosis and inflammation.
