The present invention relates to an iontophoresis device includes an electrode assembly including at least one electrode and an aqueous active agent composition, and circuitry operably coupled to the electrode assembly and configured to concurrently generate at least a continuous direct current stimulus and a pulsed current stimulus to the same electrode, the continuous direct current stimulus and the pulsed current stimulus of a character and for a duration sufficient to deliver a cosmetic composition to a biological subject. An iontophoresis method includes concurrently delivering a continuous direct current and a pulsed current to a biological subject, the continuous direct current and the pulsed current of a character and for a duration sufficient to deliver a cosmetic composition to a biological subject.
