A dermal patch includes a reservoir layer made of a polymer gel provided for receiving a liquid containing an active substance and having a first face to be applied onto the skin of a user in order to diffuse the active substance to the skin. The patch further includes a receiving layer for receiving the liquid containing the active substance and transmitting the liquid to the reservoir layer, and a layer of adhesive holding the receiving layer on a second face of the reservoir layer. The patch has the advantage of being rechargeable as required and can be manufactured without prior incorporation of the liquid containing the active substance into the reservoir layer.
