Razor having a hair-severing member having a plurality of sawing teeth arranged along a hair-severing edge of the hair-severing member. Each sawing tooth has a tooth tip and tooth edges mutually connected via the tooth tip. The hair-severing member is mounted for sawing through hairs present on the skin by means of the sawing teeth by moving each sawing tooth in a local direction of extension of the hair-severing edge at the position of the respective sawing tooth. A drive is coupled to the hair-severing member for driving the hair-severing member such that the sawing teeth move with an average velocity larger than or equal to 10 m/s. The spacing between the tooth tips of two successive sawing teeth is between 20 μm and 150 μm.

A method, a personal care system and a shaving device for providing staged shaving advice include a processor configured to receive usage data from the shaving device and personal assessment data from a user. The processor is further configured to determine and provide a shaving advice instruction presented to the user based on the usage data and/or the personal assessment data.

Staged advice for optimal use of a shaving device

A hair-cutting appliance comprising at least 19 hair-cutting units (), each comprising a guard element () and a rotatably arranged hair-cutting element () having at least one hair-cutting edge (), is provided. The hair-cutting units of the hair-cutting appliance are relatively small, a base of the guard element having a diameter in a range of 7 mm to 13 mm. In order to have a relatively small guard element () which is of robust and uncomplicated design, and which is capable of contributing to excellent hair-cutting results without causing skin irritation, it is proposed to let both an inner surface () and an outer surface () of an annular shaving track () of the guard element () have a conical shape relative to a central axis () of the guard element (), in a similar slanting orientation relative to the central axis (), in at least a hair-cutting portion of the shaving track ().

Hair-cutting appliance comprising a guard element

Razor having a hair-cutting fiber having a hair-cutting section attached to a support in such a position relative to a skin engaging surface that the hair-cutting section is exposed to a user's skin for cutting through hairs when the skin engaging surface is in contact with the skin and moved over the skin. The hair-cutting section has a fiber diameter smaller than or equal to 7 μm and is made from a fiber material having a tensile strength larger than or equal to 5 GPa. A shaving method using such a razor is also described.

Razor having a hair-cutting fiber

The present invention relates to an accessory device () for an image-capturing device () for capturing a skin image of a subject's skin comprising a tubular member () having a first opening () at its first end () configured to surround a light source () and an image sensor () included in the image-capturing device () and a second opening () at its second end () configured to surround a skin portion () and two mirrors () arranged within the tubular number () at its second end (), wherein a first mirror () is arranged to retied light () emitted by the light source () towards the skin portion () and a second mirror () is arranged to reflect light () reflected from the skin portion () towards the image sensor (). The accessory device can be coupled to an image-capturing device to acquire an image of a skin portion, which is evaluated to determine a skin parameter, such as skin gloss.

Accessory device and imaging device

Presented is a device (), comprising: a means for attaching the device to an image recording device; a mechanical means configured for applying a pre-defined pressure to skin such that skin is deformed under the pre-defined pressure; and wherein the mechanical means is adapted such that an image of the deformed skin can be recorded by the image recording device when the device is attached to the image recording device. Further, a system and a method for determining skin elasticity is presented.

The invention relates to a shaving head () comprising at least two bladeshaped cutting members (&#x2033;) each having a straight cutting edge (&#x2033;) extending parallel to a longitudinal direction (Y) of the shaving head. Each cutting member is supported in a cartridge () of the shaving head by means of a supporting member () which supports the respective cutting member in a supported area () on the respective cutting member. Said supported area extends over a predetermined distance (D) perpendicular to the longitudinal direction. Each supporting member has a first portion () in contact with the supported area at a location remote from the cutting edge of the respective cutting member and a second portion () in contact with the supported area at a location near the cutting edge of the respective cutting member. The first portion has a basic cross-sectional area, seen perpendicularly to the longitudinal direction, and the second portion has a reduced cross-sectional area. According to the invention, the second portion () of the supporting member () of at least one of the cutting members (&#x2033;) extends over at least half of said predetermined distance (D). In this manner, the free space between two adjacent cutting members is considerably increased. As a result, the rinsability of the shaving head is improved, so that the risk of shaving debris accumulation between two adjacent cutting members is reduced.
