Description

Ultrasonic beauty device for drug injection and skin care method using the same}

The present invention relates to an ultrasonic beauty device for drug injection for evenly injecting drugs into the skin and a skin care method using the same, and in particular, an appropriate amount of drug is sprayed with compressed air on the skin of a user and at the same time ultrasonic vibration is applied to the skin. It relates to an ultrasonic cosmetic device for drug injection capable of maximizing a cosmetic effect and a skin cosmetic method using the same.

In general, facial skin care using cosmetics has limitations. The reason is that a protective wall is formed with a thick protein protective layer under the stratum corneum of the epidermis, and the epidermal and dermal layers of the skin are separated by this protein protective layer, so even if cosmetics with excellent skin protection effects are used, wastes accumulated in the dermal layer are removed. because I couldn't

Therefore, for the treatment of skin diseases or skin care, it is necessary to penetrate the therapeutic agent or cosmetic composition into the stratum corneum, epidermal layer or dermis layer of the skin. However, the stratum corneum of the skin acts as a barrier not only for external contaminants or harmful substances but also for skin care or treatment drugs, making it difficult to penetrate. Drugs for skin care or treatment are slightly absorbed from the stratum corneum, but the absorption rate is very slow, so a long treatment time and a high dosage are required.

Several technologies have been developed to solve these problems and facilitate the transdermal delivery of drugs for skin care or treatment. Techniques for facilitating transdermal delivery can be broadly classified into two categories. One is to increase the permeability of the skin, and the other is to improve the flow rate in the skin. As a method of increasing the skin penetration rate, a technique of applying an electric shock to the skin is used, and as a method of improving the flow rate, an energy gradient is created in the skin to move the active ingredient down the stratum corneum, thereby increasing transdermal flow.

Recently, skin care devices using ultrasonic waves or low-frequency currents have been developed. Waves such as the ultrasonic wave or low frequency increase the production of collagen and elastic fibers in the dermis and regenerate skin cells, as well as make sagging skin healthy and elastic due to cell regeneration and blood flow increase, which is useful for skin protection and management. It has been recognized for its outstanding effectiveness.

An example of such technology is disclosed in Patent Documents 1 to 3 below.

Disclosed is a combination skin treatment device in which one of a plasma tip module and an ultrasonic vibration tip module for applying ultrasonic vibration to the skin is selectively coupled.

In addition, in Patent Document 2, a main body having a display unit capable of touch manipulation is stored on the upper part of the main body, and a handpiece in which ultrasonic waves are generated and generated in the handpiece depending on the facial part or the type of drug. and a control unit for displacing the vibration frequency of ultrasonic waves, and the handpiece includes a housing having a lower portion seated on the main body and a ceramic member installed on the inner lower portion of the housing and protruding downward, the ceramic member comprising the A first fixing part coupled to the inner lower part of the housing, a cartridge detachably coupled to the lower part of the first fixing part, an ultrasonic vibrator coupled to the upper part of the first fixing part, and a second coupled to the upper part of the ultrasonic vibrator. Disclosed is an ultrasonic device for skin drug injection including a fixing unit.
