Skin treatment apparatus utilising intense pulsed light (ipl)

A skin treatment apparatus according to any preceding claim, wherein the control system is arranged to control charging of the charge storage device prior to and/or at the same time as determination of the energy dose.

A skin treatment apparatus according to any preceding claim, wherein the control system is configured to enable charging of the charge storage device and/or one or more individual charge storage elements to a pre-determined voltage.

A skin treatment apparatus according to any preceding claim, wherein in operation the sensor is arranged to record multiple skin parameter measurements prior to determination of the energy dose.

A skin treatment apparatus according to any preceding claim, comprising an energy modulation arrangement configured to modulate supply of the treatment energy dose to the light emitting element.

A skin treatment apparatus according to any preceding claim, wherein the control system includes a discharge control element arranged to terminate the energy supplied from the charge storage device.

A skin treatment apparatus according to any preceding claim, wherein the control system is arranged to measure a discharge parameter, and the control system is configured to feedback the discharge parameter into determination of the treatment energy dose.

A skin treatment apparatus according to any preceding claim, wherein the control system is configured to enable partial charging of the charge storage device independently of the output of the sensor.

A skin treatment apparatus according to any preceding claim, wherein the control system is arranged to selectively discharge one or more of the plurality of charge storage elements to deliver the treatment energy dose.

A skin treatment apparatus according to any preceding claim, wherein the control system is configured to enable discharge from a plurality of the individual charge storage elements sequentially.

A skin treatment apparatus according to any preceding claim, wherein the control system is configured to enable discharge from a plurality of the individual charge storage elements substantially simultaneously.

A skin treatment apparatus according to any preceding claim, wherein the control system is arranged to partially charge the charge storage device dependent on the output of the sensor.

A skin treatment apparatus according to any preceding claim, wherein the control system is configured to at least partially charge the charge storage device to a voltage derived using at least one previous operational parameter of the apparatus.

A skin treatment apparatus according to any preceding claim comprising a user operable input for changing the treatment energy dose.

A skin treatment apparatus according to any preceding claim, comprising an indicator for providing information regarding the sensor measurement and/or the treatment dose.

A skin treatment apparatus comprising:

• a light source for transmitting an energy dose to the skin;
• at least a first and second sensor each sensor independently capable of measuring a skin parameter;
• a control system arranged to control operation of the light source in dependence on the first and second sensor measurements.

A skin treatment apparatus comprising a housing for housing a light source for transmitting an energy dose to the skin and at least one sensor comprising an emitter arranged to emit light to the skin and a receiver arranged to measure the intensity of light reflected from the skin, wherein the control system is configured to determine the tone of the skin from a comparison between the light reflected from the skin and the light emitted to the skin, and permit actuation of the light source to emit an energy dose to the skin if a minimum threshold skin tone is determined.
