Ultrasonic method and device for cosmetic applications

Abstract

A combination of low frequency high amplitude sonic frequency vibrations and high frequency low intensity ultrasonic pressure waves are applied to cosmetic compounds and to the skin to promote improved penetration of the cosmetic compounds into the epidermis. The cosmetic applicator device includes means for generating both sonic frequency vibrations and ultrasonic pressure waves adopted to deliver cosmetic compounds into the epidermis safely without significant temperature rise in the skin. Various removable applicator and skin cleaning attachments are also disclosed.

Description

technical field [0001] The present invention relates to sonic and / or ultrasonic devices and methods for cosmetic applications. Background technique [0002] The stratum corneum, the outermost layer of the epidermis, is made up of dead cells (keratinocytes). The purpose of this layer of dead skin is to form a barrier to protect the underlying living tissue from infection, dehydration, and chemical attack. [0003] Unfortunately, the same low-permeability barrier properties of the stratum corneum, which protects the body from infection, also resist the penetration of beneficial cosmetics and compounds, such as moisturizers, alpha-hydroxy acids, collagen, vitamins, and vasodilators. Additionally, oily and congested skin conditions also reduce the penetration of beneficial skin treatment compounds. [0004] The present invention involves methods and devices that facilitate the use of sonic and ultrasonic energy coupled to the skin to temporarily increase the permeability of th...

Problems solved by technology

This method has the disadvantage of tissue heating and associated modification and sometimes destruction of healthy cells

[0010] Despite the teachings of the prior art, the ability to safely, effectively, inexpensively and easily deliver cosmetic compounds into the skin beneath the stratum corneum remains unresolved
