SR stands for StarRomian, the original name for the MidiPlasty technology invented by Dr Justin Kim Youin, the famous plastic surgeon, scientist and inventor from South Korea. SR is used as the prefix for the various MiDiPlasty devices, for example, SRA or SRA, SRS or SRS, SRHG, etc.
Its naming convention follows that, let’s say, SRX where SR is the prefix and “X” unhyphenated represents is a series in a particular medical line.
SRX-Y where the hyphenated “Y” represents the products in question for a lifestyle, personal device or beauty line. For example, SRA-M represents the lifestyle version of SRA.
Naturally, the lifestyle or personal device can be operated by the user himself or herself, and not by a professional doctor or beautician, and the capacity is lower compared to those of the medical line series.
Last but not least, the company name is SRMC.
