Description

Fractional device for skin beauty

The present invention relates to a fractional device for skin beauty, and more specifically, for skin beauty that can maximize skin beauty effect by transferring heat energy in a state in which a needle is contacted or inserted into the skin at a predetermined length. A fractional device.

In recent years, as the interest in the skin is amplified regardless of age or gender, various methods and devices have been used to manage it. Recently, the most widely used method for skin care is the use of heat energy of frequency, which is made by inserting a very fine needle into the skin to create a treatment column, and at the same time, the epidermis to dermis through local heat damage in the skin using high frequency. To create the fine wounds that promote the regeneration of the skin to the micro-injury to induce the growth factor of the cell to maximize the natural healing of the skin. Specifically, the macrophage moves from the blood vessel to the wound in the artificially wounded area, whereby phagocytosis is eliminated, eliminates and destroys bacteria, proliferates fibroblasts and participates in the formation of new blood vessels, contributing to wound healing. Lymphocytes appear at the end of the inflammatory phase, triggering action and immune responses to foreign bodies and promoting collagen synthesis and production. The collagen produced at this time has a lifting effect of wrinkles. When the frequency is transmitted to the tissue, heat is generated by friction between molecules, and when the local temperature is increased, arterial and capillary expansion occurs by direct effect, increasing the blood flow rate and 4-5 times higher than the rest of the capillary blood flow. This increases the degree of cleansing metabolites and promotes the healing of acne and skin diseases as the supply of oxygen, nutrients, antibodies, white blood cells, etc. is increased.
