Abstract
The present application is concerned with a skin treatment device that has a handle section arranged to be held in a human user's hand, a treatment head section having a skin treatment unit and a skin contact frame having a skin contact surface, the skin contact frame at least partially encircling a skin treatment area and a vibration generation unit being coupled with the skin contact frame to vibrate at least a portion of the skin contact frame at an ultrasonic frequency.
Claims18
A skin treatment device being a light-based hair removal device or a light-based skin treatment device, comprising:
- a handle section being arranged to be held in a human user's hand;
- a treatment head section having a skin treatment unit comprising a light source and a skin contact frame having a skin contact surface, the skin contact frame at least partially encircling a skin treatment area;
- and
- a vibration generation unit being coupled with the skin contact frame to cause a vibration of at least a portion of the skin contact frame at an ultrasonic frequency essentially parallel to the skin contact surface to effectively reduce a stick-slip or static friction of the skin contact frame, wherein the vibration generation unit is configured such that a change to one of an amplitude or a frequency of the vibration results in an inversely proportional change to the other of the amplitude or the frequency of the vibration;
- wherein the skin treatment device comprises a control unit that is configured to alter at least one of the amplitude or the frequency based on motion of the skin contact frame relative to a user's skin.
