In the medical aesthetics market, consumers are interested in lifting procedures, and there are various types of equipment currently in competition. Among them, equipment using MFU technology is especially popular and its examples are ‘Ultherapy’, ‘DOUBLO’, ‘SHURINK(ULTRAFORMER)’ and ‘Linear Firm(ULTRAcelQ+)’.

MFU is a type of ultrasound. Ultrasonic waves refer to waves with frequencies of 20 Hz or more, and because of its property of being able to transmit through water, are widely used in medical fields such as ultrasound diagnosis, ultrasound therapy, etc. MFU stands for Micro Focused Ultrasound and can generate thermal effect in human tissues by focusing high intensity ultrasound on one point. It was originally used to destroy tumors and cancer cells without incision, but nowadays it is also applied to Elasticity/Lifting equipment.

Elasticity/Lifting procedures irradiate strong ultrasound energy inside the skin and generate heat to cause coagulation, in which tissues contract, pulling the skin together, and proceed to go through internal recovery which generates collagen to help improve skin elasticity and wrinkle improvement.
 
MFU lifting equipment can penetrate through 1.5mm, 3mm, 4.5mm deep into the skin, which means that the thermal energy can be transmitted to the SMAS layer, one of the main causes of skin sagging.

A great representative of MFU equipment is ‘DOUBLO’ series from one of the leading manufacturers in Korea, HIRONIC Co., Ltd, and more than 3,700 ‘DOUBLO’ series have been produced and continued its reputation. Hironic launched ‘DOUBLO’ in 2011, followed by the second-generation model ‘Doublo-S’, the third-generation model ‘DOUBLO GOLD’, and the fourth-generation model ‘NEW DOUBLO’ this year.

‘NEW DOUBLO’ is an equipment with a new concept that combines both MFU and RF(Radio Frequency) technology in order to include all of the functionalities to create a V-line shaped face.

Along with MFU, RF is also one of the most widely used energy source in lifting therapy. RF is an electromagnetic wave with a relatively high frequency, usually 20MHz or higher, and vibrates and heats water molecules in the body. For example, there are ‘Thermage FLX’, ‘Inmode’, ‘Tuneface’. Relatively newly opened hospitals often use HIFU equipment as well as RF equipment together as a combined procedure. Reflecting on the needs of the likewise market, ‘NEW DOUBLO’ is designed to perform both MFU and RF simultaneously.

Dr. Kim said that ‘NEW DOUBLO’ seems like a device that combined 10 years of know-how of Hironic and its patented technology of MFU and RF combination has made it free from side effects, producing better clinical results.

‘NEW DOUBLO’ is composed of two types of hand-pieces : FL(Focused-ultrasound Linear) and SD(Synergy Dotted).

The FL hand-piece has been upgraded from the previous generation model ‘DOUBLO’. It consists of 1.5/2/3/4.5/6/9mm cartridges and they are slimmer, providing users with more visibility for more sophisticated and meticulous procedures. Above all, it has the advantage of increasing safety with its contact detection sensor and movement detection sensor. During the procedure, if the cartridge is not tightly in line with the epidermis or not moved from one spot to another, it automatically stops the irradiation.

The SD hand-piece consists of 1.5/3/4.5/9mm cartridges and cross-irradiates HIFU and RF. By doing so, SD hand-piece can remarkably shorten the procedure time, and its pen-type structure enables to user to easily perform the procedure on narrow and curved areas.

Dr. Ki-Beom Kim, the director of Misogain Dermatology Clinic of Gimpo Branch commented that ‘NEW DOUBLO’ seems like a device that combined 10 years of know-how of Hironic and its patented technology of MFU and RF combination has made it free from side effects, producing better clinical results.

Dr. Hyo-Seung Jang, the director of Forever Clinic of Bupyeong branch, who has used ‘NEW DOUBLO’ from November last year, commented “Until Last year, the overall trend in the medical aesthetics market was centered on ultrasound, slowing moving towards radio frequency, and ‘NEW DOUBLO’ did just that” and “When I treated the patient with ‘NEW DOUBLO’, I could immediately see a positive response and it improved a lot in terms of minimizing pain and the overall result came out well.

The medical aesthetic market’s responses about NEW DOUBLO’s combining MFU and RF together has been quite positive. There certainly is a growing attention towards whether ‘NEW DOUBLO’, which is one step ahead of the trend in the market, will continue its reputation in 2022 as well.
