HIFU is a method of applying high density ultrasonic energy to a certain depth from the skin by focusing method and giving high heat and cavitation effect by pinpoint treatment, and it has been used for the treatment of tumors of organs such as prostate, pancreas, liver, etc.
In the field of cosmetic medicine, many HIFU devices including Ulthera in the United States have appeared in the past 10 years. With regard to the effects, it is known to give good results in cases where there is objectively apparent slight sagging or sagging from the chin to the neck.
However, for those who do not have such objective sagging, using equipment that delivers such high energy to tissues may cause fat tissue loss in the future. In the worst case, fat may be lost from the face, making it a rather old-lokking face.
HIFU is a very effective device if it does not go wrong with the indication, but here the expert diagnosis technology is required.
