Description

{Skin therapy handpiece}

The present invention relates to a handpiece for skin treatment that can effectively introduce a drug into the skin.

Human skin tissue consists of stratum corneum, epidermis, dermis and hypodermis, and its function is deteriorated by aging and ultraviolet rays.

Representative changes in skin due to aging and ultraviolet rays include collagen in the dermis

Skin elasticity due to degeneration of elastic fibers composed of elastin and melanin pigmentation due to activation of tyrosinase present in the epidermal layer.

A method of injecting a drug using the principle of electroporation, which is called electroporation, is a method that can cause a biological change due to an effect substance to maintain and improve the aging and elasticity of the skin.

Electrophoresis is a method of transferring materials with a certain molecular weight (less than 4000 Dalton) through the cell membrane, which is mainly used for skin cosmetic and plastic surgery and treatment of specific parts of the body. The pulse disturbs the phospholipid bilayer to temporarily create holes on the skin surface and allow the drug to enter the cell through the hole.

The holes formed by the electrical pulses are closed at the moment when the electrical pulses are stopped, and the electroporation using the electroporation is performed. The electroporation can be performed not only in the living cells but also in various kinds of molecular weights , And a prior art related to such electroporation has already been disclosed in Korean Patent No. 10-0420731.

However, in the conventional method in which an electrode plate for applying an electric pulse to the skin is applied to the skin to penetrate the necessary drug into the cell, the efficiency of the drug passes through the stratum corneum to reach the epidermis and the dermal layer, Even if a formulation or a chemical skin absorption enhancer is used to improve the transmittance, the drug may exhibit hydrophilicity, or unsatisfactory results when the molecular weight is larger than 300 Dalton.

DISCLOSURE OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a method for treating dermal layer And to provide a handpiece for skin treatment that allows the skin to be treated.
