Abstract
A laser hair removal device 10 has a base unit 12 and a hand held laser wand 14. Laser 18 generates light pulses of sufficient energy and duration to damage papilla of each hair follicle in the path of the beam. The device 10 includes one or more safety features to prevent accidental misuse of the device. In particular, the device incorporates a high intensity LED 24 which makes looking at the potential path of the laser uncomfortable, thus promoting a blinking reflex. Additionally the device may incorporate a skin contact/proximity sensor 26 to prevent use of the laser away from the skin, and/or one or more locking element to prevent accidental powering of the laser.

1-31. -31. (canceled)
- 32. A laser hair removal device (10, 110) for being directed towards and/or applied to the skin of a user to expose hair follicles to laser radiation for hair removal, said device comprising a body (14) housing a hair removal laser (18) capable of emitting radiation at a wavelength suitable for hair removal, chatacterised by a further light emitting element (24) arranged to emit a high intensity beam of radiation (21) non-injurious to the eye in generally the same direction (20) as said hair removal laser, thereby to deter a user from aiming the device towards their eye.
- 37. A laser hair removal device (10,110) for being directed towards and/or applied to the skin of a user to expose hair follicles to laser radiation for hair removal, said device comprising a body (14) housing a hair removal laser (18) capable of emitting radiation at a wavelength suitable for hair removal, characterised by a filter element (22) adjacent the end of the device to attenuate in use reflection of the beam of the hair removal laser from the skin of the user.
- 39. A laser hair removal device (10,110) for being directed towards and/or applied to the skin of a user to expose hair follicles to laser radiation for hair removal, said device comprising a body (14) housing a hair removal laser (18) capable of emitting radiation at a wavelength suitable for hair removal, characterised by a sensor (26) or detecting contact of the device with the skin and/or proximity therewith, and control means responsive to the output of said sensor (26) for inhibiting operation of said removal laser when the device is not in contact with or close to the skin.
- 41. A laser hair removal device (10,110) for being directed towards and/or applied to the skin of a user to expose hair follicles to laser radiation for hair removal, said device comprising a body (14) housing a hair removal laser (18) capable of emitting radiation at a wavelength suitable for hair removal, characterised by a control means including a timer for interrupting operation of the device after a preset period.
- 43. A laser hair removal device (10,110) for being directed towards and/or applied to the skin of a user to expose hair follicles to laser radiation for hair removal, said device comprising a body (14) housing a hair removal laser (18) capable of emitting radiation at a wavelength suitable for hair removal, characterised by control means for operating said hair removal laser, said control means including a lock for preventing unauthorised use.
