Iontophoresis is defined as the use of electric current to drive molecules across cell membranes through an electrolyte solution. In therapeutic context, it is used to facilitate the administration of bioactive substances, either systemically or locally. The technique presents various advantages and that is why it has been successfully used by a plethora of medical sciences. The constantly developing field of dermato‐cosmetic science has also taken advantage of the possibilities offered by iontophoresis, aiming to enhance the delivery of the applied active ingredients and, thus, induce the desired cosmetic effects.
