Reading Time: <1 minuteThe dark side of cosmetic medicine is deep. Even cosmetic medicine, which is a wonderful and happy medicine, is currently being used as a tool to make money. Typical of these are the exosome drip and MiraDry armpit odor businesses. In both cases, people who are not specialists or knowledgeable doctors leave the treatment to nurses, and they advertise flashily to attract customers and perform the treatment, creating a dubious business model. It is not that exosomes are bad, nor is it that the MiraDry treatment device is bad. Tests and treatments using exosomes are expected to have great potential in various fields. The Ministry of Health, Labor and Welfare has also approved MiraDry as a treatment device for primary axillary hyperhidrosis because there is evidence that it can be used. Both are drugs and devices with great effectiveness and potential. Some unscrupulous cosmetic surgery clinics have taken advantage of this and specialized in business, and this is the exosome drip and MiraDry armpit odor business. Evidence, effectiveness, and safety have not been confirmed in areas or areas outside of the indications, and there have been victims. Doctors are ignorant and nurses are leading the treatment. Do these medical procedures really have social significance and are patient-first? In many cases, cosmetic surgery is run by non-medical owners who prioritize profits, and this issue goes beyond medical ethics. The fact that major problems are occurring due to the business-first approach in cosmetic medicine is also being hidden. I strongly hope that a few unscrupulous cosmetic surgery clinics will not destroy the wonderful world of cosmetic medicine.
