The invention relates to liquid compositions for use with hair removal devices comprising a metathesized unsaturated polyol ester for improved lubrication.

According to an aspect, there is provided a computer-implemented method for providing visual feedback to a user of a rotary shaver. The method comprises (i) receiving movement measurements representing movement of the rotary shaver during a shaving operation; (ii) processing the received movement measurements to determine a representation of a trajectory of movement of the rotary shaver during the shaving operation; (iii) processing the determined representation to project the representation onto a two-dimensional plane; (iv) generating a graphical user interface, GUI, the GUI including the projected representation and a graphical template comprising an annular target zone for a correct circular motion of the rotary shaver during the shaving operation; and (v) displaying the generated GUI using a display unit.

A bladeless exfoliation head may be for a handheld skincare device. The exfoliation head may include a main body. The main body may support an exfoliation body and an interface for detachably connecting to a handle. The exfoliation body may be less rigid than the main body. The main body may include one or more exfoliation features. The one or more exfoliation features may be disposed on an exfoliation surface of the exfoliation body. The exfoliation surface may be opposite the exfoliation head from the interface. The exfoliation head may be provided in a skincare kit or even a shaving kit.

According to an aspect, there is provided a computer-implemented method (300; FIG. 3) for interacting with a user of a personal care device (FIG. 1; 102). The method (300; FIG. 3) comprises receiving (302, FIG. 3) device usage data indicative of a manner in which the personal care device is used by the user during a usage instance of the personal care device, the device usage data relating to one or more of a defined set of device usage parameters; receiving (304) performance data indicative of an outcome of the usage instance, the performance data relating to one or more of a defined set of performance parameters; and responsive to a determination that one or more of the received device usage data and the received performance data differ from stored reference device usage data and stored reference performance data, respectively, by more than a defined threshold amount, generating (306) a user input request to be presented to the user. An apparatus, a system and a computer program product are also provided.

A personal care bottle with a distal end portion and a proximal end with a shoulder. A collapsible bag is positioned within the bottle. The collapsible bag configured to contain a liquid. A cap defining an opening having a frangible seal is cap mounted to the proximal end. The bottle has an outer surface defining a groove extending from the shoulder toward the distal end portion.

A modular wireless appliance charging system includes a primary charging platform having a plurality of adapter slots disposed on its upper side. An adapter is configured to be removably secured within each adapter slot. Each adapter includes a receiver configured to removably secure an appliance to the adapter via a charging port of the appliance. A power supply is operably connected to a charging mechanism which is configured to charge the battery of the appliance that is secured to the receiver of an adapter that is secured within one of the adapter slots. An auxiliary platform having similar components can be connected to the primary platform to expand the system's charging capacity. The adapters can include many configurations for different types of appliances. In this way, the user can customize their charging system to include a specific type, number, and order of adapters for organizing and charging their battery-powered appliances.

The invention provides a facial hair shaping tool and comb for personal grooming, including a first guide member and a second guide member that are identical or nearly identical in size and shaped like a comb with a handle, coupled at a centerline separating the first guide member and the second guide member at two end portions. Each guide member is relatively thin compared to its overall size, having an elongated planar body with at least one curvilinear segment, and includes additional members that allows the facial hair shaping tool and comb to convert between a conjoined facial hair shaping tool (opened state) to a miniature comb (closed state), and vice versa.
