Single layer and multilayer vesicles with actives inside are delivered into living tissue. Then, the vesicles are disrupted using ultrasound. The vesicles are used to create an image in the tissue or for the delivery of certain actives to the skin.

Systems, devices, and methods including encapsulated cosmetics

The appliance includes an appliance body/handle and an interface assembly for receiving a detachable workpiece. The body/handle includes a signal-generating assembly with electrical connections to the appliance body interface. The signal-generating assembly is controlled by a microprocessor, which generates signals adapted to control and operate the workpiece which is attached to the appliance. A plurality of workpieces are included which are individually adapted for treating various spot skin irregularities. The appliance further includes a system for identifying the workpiece attached, so that appropriate operating signals can be generated and provided to the attached workpiece.

Skin treatment appliance with changeable workpiece

An apparatus and method is provided for skin treatment. An apparatus includes an applicator assembly that includes an applicator tip which is configured to apply a normal cyclical mechanical force to a skin surface area of a user and to deliver a skin formulation to a skin surface area of a user. The apparatus further includes an electromagnetic energy assembly that includes at least one electromagnetic energy source adjacent to or within the applicator assembly and is configured to deliver pulses of electromagnetic energy stimulus of a character and for a duration sufficient to penetrate one or more dermal layers within the skin surface area of a use.

Apparatus and method for skin treatment using pulsed light

An apparatus and method is provided for skin treatment. The apparatus includes an applicator assembly that includes an applicator tip which is configured to apply a normal cyclical mechanical force to a skin surface area of a user and to deliver a skin formulation to a skin surface area of a user. The apparatus further includes an electromagnetic energy assembly that includes at least one electromagnetic energy source adjacent to or within the applicator assembly and configured to deliver a continuous electromagnetic energy stimulus of a character and for a duration sufficient to penetrate one or more dermal layers within the skin surface area of a user.

Apparatus and method for skin treatment using continuous light

An oral hygiene device having an ultrasound transducerand an acoustic waveguidefacilitating the transmission of ultrasonic acoustic energy to fluids in the oral cavity is disclosed. Preferred ultrasound operating parameters for operation in aqueous environments and in dental slurries are disclosed. Devices may incorporate a drive motorfor oscillating a device head, acoustic waveguideand one or more bristle tuft(s)at sonic frequencies, and preferred sonic operating parameters are also provided. Multi-element piezoelectric transducer assemblies, and various control and communications features are disclosed. Oral hygiene devices disclosed herein achieve improved plaque and stain removal from the teeth as well as interproximal and subgingival regions, while enhancing the user experience, massaging the gums, stimulating dental tissue, and disrupting biofilm.

Ultrasonic toothbrushes employing an acoustic waveguide

Methods are included for quantitating the efficacy of oral care products at dislodging cells from biofilm test surfaces or inhibit or delay the accumulation of cells on a test surface. More specifically, the inventive methods measure the effectiveness of compositions and appliances in a test environment that models biofilm surface orientations that are encountered on a tooth surface, i.e. interproximal and subgingival tooth surfaces. The use of test surfaces that are removably attachable to a tooth prosthesis allow a variety of different quantitative methods to be applied to determine the amount of cells removed or deposited in a biofilm.

Methods for quantitating the efficacy of oral care products

A brushhead for an acoustic powered toothbrush having a particular bristle configuration which includes a plurality of bristle portions arranged in four columns and eight rows, wherein the distal end two adjacent rows and the proximal end two adjacent rows both have longer bristles than the remaining bristle portions except for an intermediate row of bristle portions which are slightly longer than the longer bristle portions. The distal, intermediate and proximal bristle portions all have pointed bristle portion tips.

Brushhead for use in an acoustic toothbrush

An electric toothbrush (10) with an adaptive load sensor (12) is disclosed. The toothbrush of this invention includes a brushhead (16) that is vibrated by a drive assembly (18). The load sensor monitors the current drawn by the drive assembly to determine the mechanical load to which the toothbrush is exposed. The load sensor assembly produces an adaptive threshold signal that represents the instantaneous maximum pressure load. If the sensed load voltage exceeds the adaptive threshold signal, the load sensor assembly deenergizes the drive assembly and generates an alarm signal so as to give the user a warning that the toothbrush has been excessively loaded.
