Concept:  Zinc : a universal antiseborrheic and essential oligo !
Its antiseptic activity limits bacterial colonization
The L-PCA, :  physiological all-purpose agent for a better bio-availability

Mode of action: Known for its action in inhibiting 5-α-reductase, zinc is a specific trace element for seboregulation. Zincidone®, a
combination of zinc and L-PCA, helps regulate the activity of the sebaceous glands and reduces the level of skin sebum in vivo. Its action on bacterial proliferation, notably on Propionibacterium acnes, helps limit the resulting irritation.
