Abstract: The present invention relates to an electroporation process for delivering a composition through human keratin materials, the composition comprising at least one hydroxy acid compound, the electroporation process involving exposing the composition in contact with said keratin materials to pulse trains of a pulsed electric current, the pulsed electric current being provided by an electroporation device having at least one electrode and at least one counterelectrode, the pulse trains of the pulsed electric current repeating at a frequency of between 0.1 Hz and 1 kHz, the pulse trains each having a duration (Ton) of between 0.001 s and 2 s, and the pulsed electric current having a voltage amplitude ranging from 20 V to 250 V and a current ranging from 0.1 mA to 10 mA.
