Disclosed is a drug delivery method using a cavitation seed and a cavitation seed for delivering a drug. A cavitation seed according to the present invention includes a shell forming an outer surface to maintain an outer shape in a fluid and a core positioned inside the membrane and determining buoyancy of the cavitation seed in the fluid do. Therefore, cavitation due to ultrasonic waves is induced near the epidermis, so that the drug delivery effect can be improved in the body. In addition, the present invention can be applied not only to skin treatments such as skin whitening, depilatories, hair extensions, skin fillers, skin analgesics, local anesthetics, genetic diseases such as psoriasis, skin cancer and the like but also various drug delivery. |
