    • The first innovative active ingredient resulting from Pierre Fabre Biotechnology: Celastrol, 100% natural active ingredient produced from plant cell culture, a soothing active ingredient which specifically targets the Th17 pathway (IL-17) involved in psoriasis. It acts directly on keratinocytes to reduce the onset of plaques and thus improve the skin's appearance.
    • VederineTM promotes cell differentiation which helps plaques detach from the skin more easily.
    • Ichtyol slows down the cell renewal and thus limits the appearance of new scaly plaques. Cell renewal in normal skin: 21-28 days versus 3-5 days for psoriasis-prone skin. 
    • Salicylic acid is a keratolytic active ingredient that helps eliminate visible plaques on the scalp.
