Device and method for skin treatment
The invention relates in general to the field of human skin treatment, more specifically to devices and methods for cleansing and subsequent care of a person's skin. The methods effectively use the combination of mechanical cleansing strengthened by vibrations transmitted to a tip, lowered pressure and treatment liquid. The advantageous aspect of the device according to the invention is that vibrations are transmitted from the vibration mechanism directly to at least a portion of the tip that is in contact with the patient's skin. This means that vibrations are targeted to the place of use, and the vibration of the whole applicator is, in comparison with methods and devices according to the state of the art, significantly lowered, as are occurrences of hand pain and other inconveniences for the person providing the therapy. The other advantageous aspect of the device is a special design of the applicator for reducing the risk of spilling serum when treatment is stopped or interrupted.
