In order to craft artisanal soap, the day at the Domaine d'Esthine starts with the manual milking of the donkeys whose remaining milk is destined for the young. Thanks to a cold saponification technique, the natural fat of milk remains intact. The essential oils added to the mixture are made from plants grown in organic farming without palm oil. Rich in vitamins and trace elements, donkey's milk proves to be a natural tensor. Its softening and restructuring properties work effectively on weakened skin.
