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. The base device may thermally modify the material that is then coupled to the applicator and applied to the treatment surface during treatment. Application of the applicator at the desired temperature to the treatment surface may, for example, stimulate deeper blood circulation, clear pores, diminishes or removes deep and fine wrinkles, accelerate acne clearing, treat blemished skin, decrease edema and erythema of the skin, and / or reduce puritis of various etiologies. The hand piece may comprise one or more secondary treatment elements, such as LEDs for photoactivation, electrodes for delivery of micro-currents or vibrating elements for rubbing or abraiding, in order to achieve additional activation of the treatment surface and / or of the thermally modified material coupled to the applicator, which may enhance or improve treatment.

A garment seam is formed between two fabric panels by abutting the edges of at least two panels and placing a strip of material carrying adhesive on the abutted edges to form the seam. The fabric panels have opposing major surfaces, the edges of the fabric panels being minor surfaces. The strip of material is applied on at least one major surface of the abutted fabric panels, but is optionally applied to both major surfaces of the abutted fabric panels. The strip of material is preferably thinner than the fabric panels. In some embodiments, the adhesive is a thermosetting adhesive that is applied on the strip of material in liquid form. A seam manufactured according to the present invention is less detectable through clothing than conventional multi-ply seams. Also the adhesive seam enables the manufacturer to tailor the garment to provide support or shape in a particular area (i.e. the area of the seam) in addition to providing the desirable smooth appearance. For example, when used in a brassiere (bra) cup, the seam allows the garment to be designed to provide optimal comfort, shape and support to the wearer.
