how it works
the day serum is an integral part of skin regenis revolutionary anti-aging system, characterized by the use of two distinct products, one for use during the day, and the other at night, to better respect and enhance chronobiological rhytms. Vitamin PP and yeast extract inhibit the sirtuins. sirtuins are proteins present in the cells and are known as "longevity proteins" because of their ability to prolong the life span of the cells, and give extra time to the cells to repair themselves and return to life. considering the studies of chronobiology, the mechanism which activates the sirtuins is favourable at night, but not favourable during the day because the main activity of the skin duing the day is protection and not reparation. for this reason, inhibitors of the sirtuins activation are the primary actives of the day serum

how to use
during the day after cleansing and toning the skin, apply the serum and massage gently until completely absorbed. If desired, a day cream can be applied afterwards, with the exception of action sublime cream spf12 and the absolute pearl line which are preferred at night
