| 1. A cosmetic treatment apparatus comprising:
a discharge lamp for generating light for a cosmetic treatment;
a capacitor for providing an electric current for operating the discharge lamp;
a circuit for operating the discharge lamp in response to the electric current provided by the capacitor; and
a current controller for controlling the electric current flowing from the capacitor to the circuit, wherein the current controller
is disposed between the capacitor and the discharge lamp,
and further wherein the capacitor voltage decreases when the current flows from the capacitor to the circuit and the current
controller is operative such that during at least a first part of the cosmetic treatment the current controller controls the
current flowing to the circuit to be substantially constant, and during at least a second part of the cosmetic treatment the
current controller controls the current flowing to the circuit to depend on the capacitor voltage.
