Description

Ultrasound delivery and drug application combined skin care device {SKIN CARE DEVICE FOR ULTRASOUND DELIVERY AND DRUG APPLICATION}

The present invention relates to a skin care device that combines ultrasonic transmission and drug application.

Skin care devices for removing wrinkles, restoring skin elasticity, and removing sebum have been developed. This is because skin that is wrinkle-free, taut, thick, dense, and free of sagging makes a person look younger and contributes to an attractive appearance.

There are several types of skin care devices, such as a method of outputting high-intensity focused ultrasound to the skin (HIFU type), a method of transmitting high-frequency waves to the skin (RF type), and a method of irradiating laser light to the skin (Optical type). .

When electrical energy such as high-intensity focused ultrasound, high frequency, and laser light is delivered to the skin, damaged collagen, elastic fibers, etc. are removed from the skin and new formation is promoted. Skin pigmentation, acne scars and wrinkles can be improved.

On the other hand, drugs are applied to the skin to alleviate pain caused in the process of transmitting electrical energy to the skin and to treat fine wounds.

However, conventional skin care devices have a problem in that ultrasonic waves and drug application cannot be performed simultaneously on the skin.
