An applicator for a skin care product is provided, together with a cosmetic skin care product comprising an applicator and a skin care composition, and a method of using the applicator to regulate a skin condition. The applicator has a substrate with a magnetic array printed thereon, the magnetic array having at least one layer of one or more dipolar pairs of alternating magnetic poles. The applicator further has a vibration source. The magnetic field strength generated by the magnetic array is at its maximum at the poles. When activated, the vibration source causes side to side movement of the applicator, meaning that the full magnetic field is experienced by all diamagnetic materials to which the applicator is applied.
