SONIC METHOD AND APPARATUS FOR COSMETIC APPLICATIONS

摘要

Sonic pressure is applied to the skin of sufficiently high intensity to cause sonic vibrations (2) within the skin. A therapeutic agent (20) is applied to skin either before or promptly after the sonic pressure waves are applied to the skin. The device (1) includes a rigid handle (16) and a flexible applicator (3). A motor (13) within the handle (16) has a weight eccentrically (11) mounted on the output shaft (17) thereof to cause rotary vibrations of the handle (16) about its central axis (4) which are translated into linear vibrations of the applicator (3). Sonic pressure waves are applied in repetitive burst type modality, and ultrasonic pressure waves may be applied between the bursts of sonic waves (2) to control the depth of penetration of therapeutic agents.
