Re-sleep is Rilastil’s chronobiological line able to take advantage from body’s circadian rhytms. During night sleep the skin is most disposed and receptive to active ingredients’ action and this line makes fully use of this potentiality. The formulations, with the exclusive active ingredient Tetrapeptide-26, help to strengthen the natural systems of repair, replication and protection of the skin cells, thus favouring the synchronization of the circadian rhytms and optimizing other active ingredients’ efficacy: in the morning, the skin is regenerated and more elastic.
