1. A skin treatment apparatus, said apparatus comprising:

  • a handpiece with a source of skin treatment radiation configured to generate intense pulsed light radiation;

    a control unit for controlling a variable radiation parameter of said intense pulsed light radiation generated from said source, wherein the variable radiation parameter includes one or more of a power, a pulse duration or a pulse frequency per activation, wherein the control unit is part of a separate handheld unit than the handpiece;

    a base unit including a processor, the base unit having cradles configured to enable docking and undocking of the handpiece and the control unit therein;

    a sensor on said control unit for sensing a skin parameter, wherein the skin parameter includes one or more of a skin tone, a skin layer thickness, a level of oiliness, or a skin blood parameter; and

    an actuator for enabling a user to interface with said control unit;

    wherein said control unit is configured to operate in a sensing mode when said control unit is undocked from said base unit, and, in the sensing mode;

    said sensor is configured to sense the skin parameter, andwherein said control unit is configured to operate in a control mode when said control unit is docked to said base unit, and, in the control mode;

    said control unit automatically transfers the skin parameter sensed by the sensor in the sensing mode to the processor of the base unit and selects a skin safety limit for the variable radiation parameter based on the sensed skin parameter;

    said processor initiates the source to charge at the automatically selected skin safety limit of the variable radiation parameter; and

    said actuator is configured to further permit changing the variable radiation parameter manually, but not beyond the automatically selected skin safety limit.
