Sederma’s eco-designed active ingredient for pollution-defence Citystem® is once again on the radar. After recognition with the PCHi Fountain Award for Outstanding Active Ingredient in February 2017 for its superior performance in fighting against visible and invisible pollution damage to the skin; and after having been demonstrated in May 2017 as an effective solution for the protection of skin against the harmful effects of blue light irradiation; it is back in the news today for its proven ability to protect and restore the autophagic activity of skin cells. Sederma has highlighted the damaging effects of pollution on the autophagic capabilities of skin cell and, in parallel, the ability of Citystem® to counteract this deterioration. As an autophagy activator, this plant cell culture extract detoxifies the cells, and thus ensures their sustainable viability. Citystem® is a proven perfect solution for the protection of skin health and beauty from pollution-induced damage.
