The present invention discloses a device and a method for controlling growth of hair on human skin with low doses of electromagnetic radiation, and a device for carrying out the method. In the method, radiation of a suitable spectrum is applied to the skin, in one or more pulses of between 1 and 100 ms, and with maximum fluencies on the skin between 1 and 12 J/cm2. By applying such low fluencies and at controlled pulse durations, follicles of the hairs are induced to the catagen phase. This means that the growth of the hairs of those follicles will stop. Although the method is not primarily aimed at immediate hair removal, hairs may be shed subsequently. In any case, further growth may be stopped for prolonged periods of time. The main advantage of the method is that the risk of damage to the skin is minimized.

Device and method for low intensity optical hair growth control

The invention provides a treatment device () for fractional laser-based treatment. The treatment device comprises a treatment generator () comprising a treatment laser () and a laser scanning system (). The laser scanning system comprises at least one movable deflection element and is configured and arranged for scanning laser light across an emission window () towards skin tissue () from a plurality of locations () in the emission window by moving the at least one deflection element relative to the emission window, whereby, in use, laser-based lesions () are generated inside the skin tissue. The treatment device also comprises a controller () for generating a predefined disposition of lesions () in the skin tissue by emitting laser light via selected ones of the plurality of locations in the emission window while the treatment device is moved relative to the skin surface (). The controller is configured for generating an area disposition of the lesions by scanning the laser light across the emission window using the laser scanning system and deflecting laser light into the skin tissue via the plurality of locations while the treatment device is moved relative to the skin surface, whereas in the line treatment mode the controller is configured to generate a line disposition of the lesions inside the skin tissue from a single predefined location of the emission window by maintaining the at least one deflection element in a stationary position relative to the emission window while the treatment device is moved relative to the skin surface.

Treatment device for area and line fractional laser treatment

A treatment device for fractional laser-based skin treatment includes an emission window having an elongated area and predefined locations that are arranged in an elongated array which extends along a treatment axis of the window. A treatment generator has a treatment laser for emitting laser light towards skin tissue from the predefined locations in the emission window for generating, in use, laser-based lesions inside the skin tissue. The treatment device also includes a motion sensor for sensing motion of the treatment device relative to the skin surface, and a controller for determining a non-zero sequence of at least one of the predefined locations from which laser light is consecutively emitted in dependence on the sensed motion. The controller allows generation of the non-zero sequence when the sensed motion of the treatment device relative to the skin surface only has a component in a direction parallel to the treatment axis.

A photo-epilation device including a hand-held housing with at least one window opening; a lamp accommodated in the housing for generating light having a spectral range from approximately 575 nm to approximately 1700 nm; and a control device for driving the lamp. The lamp is switched on in brief pulses having a pulse duration in the range from 1.1 ms to 1.9 ms, and a pulse repetition frequency in the range from 0.1 Hz to 0.5 Hz. The fluence on skin level is in the range from 2 to 7 J/cm2, dependent on the skin type.

Photo-epilation device

The present invention relates to a skin treatment device (, F). The device comprises a radiation source () in a housing, such that radiation can be emitted through an exit opening in the housing. It further comprises at least one skin presence sensor () capable of measuring the presence of skin () in a number of respective positions, and a control unit (). The control unit () is constructed to determine a covered portion of the exit opening () from a measurement signal of the skin presence sensor and to restrict emission of the radiation () to the covered portion of the exit opening (), e.g. by modifying the control of a radiation beam manipulator (), or by controlling radiation-blocking means, such as blinds, in the exit opening (). The invention provides a more efficient and yet safe treatment device (), since a larger exit opening () can be selected, while unwanted emission of radiation () through uncovered portions of the exit opening () is still prevented.

Skin treatment device with radiation emission protection

A device treats skin by radiation. The device has a housing accommodating a radiation source and having an exit opening for the radiation. The device activates the radiation source only if the presence of skin immediately in front of the exit opening is detected. The radiation source cannot be activated if the exit opening is not covered.

Skin treating device comprising a protected radiation exit opening

A device for the treatment of skin by radiation pulses. The device has a detector measuring a biophysical property of skin, such as temperature increase, dispersion or absorption coefficient, or reflection coefficient for light having a predetermined wavelength, and also has a control unit which determines, from the biophysical property, a safe dose of radiation. The device automatically protects against an overdose from the radiation source. The invention can be used, not only in a hair removing device such as a laser epilator, a laser shaver or a flashlight epilator, but also in devices for the medical treatment of skin by means of radiation, such as photodermatology systems.

Skin treating device with protection against radiation pulse overdose

An alignment device, for use in a lithographic apparatus, for aligning a first object, provided with a first alignment mark relative to a second object, provided with a second alignment mark, employs as a radiation source a laser which emits an alignment beam having a wavelength which is of the order of 1000 nm and to the order of 1100 nm.

Alignment device and lithographic apparatus comprising such a device

The invention relates to a depilation apparatus, comprising a housing which accommodates a pinching member for consecutively pinching hairs growing from human skin and twisting the pinched hairs about their longitudinal axes. According to the invention, the pinching member holds the pinched hairs in a substantially constant position relative to the housing while twisting the hairs. In this manner, the pinching member does not pull at the hairs and, therefore, does not cause any pain while twisting the hairs. The hairs are twisted by the pinching member until the adhesion between the hairs and the skin tissue is broken or until the hairs are broken beneath the skin surface. After having been twisted in this manner, the hairs can be removed from the skin substantially without pain. The pinching member of a preferred embodiment of the depilation device comprises at least two co-operating pinching elements which are periodically movable from a hair trapping position to a pinching position and from the pinching position back to the hair trapping position, the pinching elements sliding along one another in the pinching position at speeds which are equal but oppositely directed relative to the housing.
