Methods, apparatus and systems for personal care, such as treatment of a skin or hair treatment surface, are disclosed. In some embodiments, a base device is configured to thermally modify (heat or cool) an applicator on a hand piece that can then be used to cleanse, treat and/or otherwise rejuvenate the treatment surface. The applicator can be formulated with a smooth or abrasive material that can absorb, be coated with or otherwise take up a variety of materials, such as liquids, lotions, gels or creams, which are suitable for application to the treatment surface.
