A skin treatment system (1) such as a depilating system comprises a functional member (20) that is configured to perform a treatment action on skin (2) and to be moved over the skin (2) during operation of the system (1), and a measurement unit (40) including a measurement member (41) that is configured to also be moved over the skin (2) during operation of the functional member (20) and to contact the skin (2) in the process. The measurement unit (40) is configured to measure at least a force value in an advancing direction in which the measurement member (41) is moved over the skin (2) during operation of the functional member (20). The measured force value in the advancing direction is used for the purpose of determining a friction coefficient value representative of the friction coefficient of the skin (2), which allows for assessing skin condition.

A hair pulling device includes a machine body which is provided with a hair clamping support (1) and a driving device. A fixation shaft (3) which is fixed and non-rotary as well as a plurality of positioning frames (2) which are driven by the driving device to rotate around the fixation shaft (3) are disposed on the hair clamping support (1); a plurality of groups of hair clamping assembly units which are rotated with the positioning frames (2) are disposed, along an axial direction of the fixation shaft (3), on the positioning frames (2); the fixation shaft (3) is fixedly sleeved by a positioning shaft (4); The hair pulling device has high hair clamping efficiency and reliable and stable clamping force, and avoids the problems that hair pulling fails due to failure of an elastic part or hair pulling fails due to insufficient clamping force.

The present invention relates to mechanical hair removal. In order to provide a handheld hair removal apparatus with improved detection of fine hair, a handheld hair removal apparatus (10) is provided that comprises a hair removal arrangement (12), a support structure (14) for supporting the hair removal arrangement, and a light source (16) attached to the support structure. During operation, a main movement direction (20) of the apparatus is provided. The hair removal arrangement comprises a skin contact portion (22) extending at least along a primary axis (24) extending perpendicularly to the main movement direction for contacting a user's skin during operation. Further, the light source can be arranged in an operational position (P.sub.O) at a side of the hair removal arrangement in front of the skin contact portion with respect to the main movement direction. Still further, in the operational position the light source provides a light beam (28) with a main propagation axis (30) enclosing an angle of incidence (32) of less than 30° with an imaginary plane (33) extending parallel to the main movement direction and the primary axis.

A beauty device (1, 2, 3) includes rollers (220, 226-1, 226-2), at least one part of which is in contact with skin and a center portion and an end portion of which have different diameters, an irradiation unit (212) that irradiates the skin with light, and a control unit (130, 315, 135, 316) that controls the irradiation unit based on the rotation of the rollers.

The present invention is concerned with an electrically operable hair removing device, such as a shaver comprising a housing, an energy source located in the housing, at least one hair removal unit and at least one electrically operated equipment, like a light source, which is movable relative to the housing. During its use, the at least one electrically operated equipment is not directly connected to the energy source located in the housing.

The present invention is concerned with an electrically operable shaver with an elongate shaver housing defining a longitudinal axis (I), at least one short-hair cutter unit, at least one long-hair trimmer unit disposed on the shaver housing and at least one light source. The at least one light source is movable substantially parallel to the longitudinal axis (I) between a retracted position and an extended position.
