Abstract:
A brush comprises a plurality of filaments having a crimp structure and a J structure to provide a full distribution of filaments at an end surface of the brush, wherein the crimp structure of a majority of the filaments is configured with a period length of 2 mm to 5 mm and a peak to peak length of not greater than 0.8 mm, and the J structure is configured with a long length about 0.02 inches to about 1.2 inches, and a difference between the long length and a short length is about 0.2 inches to about 0.5 inches.
Abstract:
The present disclosure seeks to address the primary problem of long application durations to deliver an effective dose of an active ingredient. The devices combine mechanical motion with electrically induced flux (e.g., iontophoresis). The combination of techniques in a single device can reduce the treatment time required to deliver the active ingredient in an effective dose, or deliver a larger dose over the same duration of application.
Abstract:
A cleansing workpiece suitable for use with a personal care appliance. The cleansing workpiece includes a cleanser and a cleansing component, such as a number of tufts each having a plurality of bristles. In use, the cleansing workpiece can be rotated, reciprocated, oscillated, etc., over a subject's skin in order for the cleansing workpiece to dispense or apply a quantity of the cleanser onto the subject's skin and/or for the cleansing component to clean, massage, and/or exfoliate a subject's skin with the aid of dispensed cleanser. The cleanser may be continuously applied to the subject's skin as the cleansing component.

Abstract:
Exfoliating brush heads are disclosure for use with a personal care appliance. The personal care appliance is configured to oscillate the exfoliating brush head to provide improved smoothing and exfoliation of a patient's epidermis with or without the antecedent application of skin care formula. The oscillating action of the exfoliating brush head may be rotational, translational, or a combination thereof. In use, the personal care appliance oscillates the exfoliating brush head over a patient's skin in order to remove dead skin from the patient's epidermis. The exfoliating brush head may include first and second groups of tufts, wherein the first and second groups of tufts have different bristle heights and/or stiffness.
