Definitions

  • This invention relates to a skin cleaning device and method.
  • the pores of the skin comprise a channel which leads to the sebaceous gland, where sebum is produced.
  • Sebum is an oily substance which provides waterproofing and lubrication of the hair and skin. The sebum can give rise to an oily coating on the skin.
  • Newly generated sebum is situated at the base of the pore at the sebaceous gland.
  • the pore shaft contains stored sebum, and released sebum resides on the surface of the skin.
  • Surface cleaning products include brushes and blotting sheets (e.g., sebum absorbing sheets). The effect of surface cleaning only lasts only for several hours since only the superficial sebum is removed, not the sebum in the shaft or sebaceous gland.
  • Deep cleaning can be carried out using brushes, which can remove sebum in the pore shafts, as well as surface sebum.
  • brushes which can remove sebum in the pore shafts, as well as surface sebum.
  • the effect is likely to be limited since the brush hairs move laterally across the pores and can thus not reach deep into the shafts because of the stroking motion. The effect does however last longer than just surface cleaning.
  • Manipulation of the sebaceous glands is also a known approach.
  • intense pulsed light such as pulsed laser light
  • Photodynamic therapy has also been proposed to destroy the sebaceous gland based on the use of photosensitizers (e.g. aminolevulinic acid) which produce a photo-toxic effect.
  • photosensitizers e.g. aminolevulinic acid
  • These are professional treatments used only for severe medical conditions such as acne and cancer, in which reduced sebum generation is believed to be desirable.
  • these approaches are not suitable for home use.
  • These approaches will however give longer term advantages.
  • the treatment can be carried out only once every few weeks or so. Excessive treatment can however cause dry and vulnerable skin, in addition to a risk to the eyes and/or skin caused by overexposure to intense light.

  • the cleaning surface for application to the skin, the cleaning surface comprising an array of orifices
  • a force sensor configured to sense a force applied by the hand held unit against the skin and provide a feedback based on the sensed force.
  • the device is designed to be pressed against the skin.
  • Each orifice forms a skin cleaning area, which enables the skin pores to be manipulated by the positive pressure applied to the skin as a whole by means of the walls around the orifices.
  • the device provides effective manipulation of the skin with force feedback.
  • the device is moved across the skin in use while maintaining the positive pressure to the overall hand held unit.
  • the speed of movement may for example be in the mm/sec range.
  • the manipulation of the skin then enables more effective cleaning while or after the mechanical operation is complete.
  • the hand held unit further comprises a pump configured to provide suction to the orifices. In this way, the cleaning takes place simultaneously with the mechanical operation.
  • each orifice defines cavities to which the suction can be applied.
  • each orifice forms a skin cleaning area, which enables the skin pores to be manipulated by the combination of the suction within the cleaning area and the positive pressure applied to the skin as a whole by means of the walls around the orifices.
  • the device in this preferred example thus combines positive force applied mechanically with suction applied
  • Each orifice may be defined at the tip of a raised ridge. This ridge functions to provide a desired pressure to the skin, in response to a particular force applied to the overall device against the skin. The desired pressure causes manipulation of the skin to assist in removal of sebum from the pores.
  • the device may further comprise a heating unit for providing heating to the skin in the vicinity of the cleaning surface.
  • a heating unit for providing heating to the skin in the vicinity of the cleaning surface.
  • the heating unit may comprise a near infrared light source. It may be adapted to generate an output temperature which gives rise to a temperature at the skin surface in the range 40 to 45 degrees Celsius.
  • the skin surface typically has a temperature about 34-35 degrees, and can tolerate temperatures up to around 45 degrees for a reasonably long time (e.g. 10 minutes) with only transient and very mild irritation, which ceases immediately after removal of the heating.
  • the heating is thus preferably controlled to raise skin temperature to no higher than 45 degrees.
  • a temperature range 40 to 45 degrees may achieve a desired decrease in sebum viscosity, to assist in removal of sebum from the skin surface and at least partially from the skin pores.
  • the device may comprise a handle part, and the force sensor can comprise a spring device between the cleaning surface and the handle part of the device.
  • the spring device compresses in response to a force applied, and the degree of compression can be used to generate an output indicating the pressure being applied to the skin.
  • the spring device may reach a limit of compression at a limit force
  • tactile feedback may be provided which informs a user when e.g. a desired force or a maximum force is reached.
  • An output device may be used to provide an output which is indicative of the force applied. This can be used to guide the user to apply a force which is in a suitable range for the most effective operation of the device. In particular, the force applied influences how the skin will be deformed locally within the skin cleaning areas formed by the orifices.
  • the output may be an audible signal or a visual signal, or else tactile feedback may be used.
  • the output may for example positively indicate when a threshold force level is exceeded, or it may positively indicate when the force is within a desired range.
  • the range of forces indicated to the user as appropriate may be selected to correspond to a pressure range of IMPa to 5MPa applied to the skin.
  • IMPa may be considered to be a minimum pressing force for the function to take effect, whereas the user may start to feel pain at about 5MPa.
  • the maximum pressure is therefore preferably less than 5MPa.
  • the array of orifices may comprise an array of elliptical openings or rounded rectangular openings. These shapes allow a compact arrangement of hollows with thin and all-curved (i.e. not presented sharp edges) ridges in between.
  • Each opening may have a long-axis dimension in the range 4mm to 6mm and a short axis dimension in the range 2mm to 4mm.
  • one preferred size of the opening is 3mm on the short axis and 5mm on the long axis.
  • An opening too small leaves a hollow cavity space which is too small for skin to deform locally.
  • An opening too large disperses the applied force thus diminishes the extrusion effect and also has difficulty adapting to the ups and downs in the skin contour.
  • the ridges between the orifices may have an average thickness between 0.2mm and 0.5mm.
  • the ridge might be as thin as possible but without presenting a sharp face, for example no thinner than 0.2mm. Ridges that are too thick shield pores beneath the ridge area from being pressed, and thus reduce efficiency.

  • a filter may be provided in the suction duct. This can be replaceable or cleanable to provide a device with a long lifetime.
  • the hood may comprise transparent or translucent portions and reflecting portions, wherein the heating unit is mounted outside the hood, and the heating unit output is directed to the skin in the vicinity of the cleaning surface through the transparent or translucent portions.
