Physical and mathematical analysis for optimizing non-invasive monopolar radiofrequency strategies to enhance safety and efficacy

Monopolar radiofrequency (MRF) therapy, a popular treatment in aesthetic medicine, depends on the importance of operator skill and a solid understanding of physics and facial anatomy. High-frequency ultrasound measurements of skin thickness may provide information on the thermal relaxation time, and we can use this information to combine with cooling systems and ensure safe and precise treatments. Besides, we can use the patient feedback scale for further support using multiple passes at the highest tolerable energy level to accumulate heat for optimal outcomes effectively. The efficacy of MRF resides in the heat accumulation following an exponential-like curve, which may be attributed to the heat transfer model and Arrhenius equations, making multiple-pass techniques essential. MRF therapy, enhanced by these methods, remains a cornerstone of aesthetic treatments, improving results and reinforcing its crucial role in the field.

Monopolar radiofrequency (RF) technology has gained significant attention in the field of dermatology as an effective non-invasive treatment for skin aging, including wrinkles, skin laxity, and hyperpigmentation. RF devices work by delivering electromagnetic energy deep into the dermis, generating heat that stimulates collagen production and remodeling, which leads to skin tightening and improved texture. In particular, monopolar RF targets deeper layers of the skin while protecting the epidermis, providing a safer and more controlled treatment option for patients. Clinical studies have consistently shown that RF treatments result in notable improvements in skin firmness, wrinkle reduction, and even skin tone.
Among the available RF devices, Thermage FLXⓇ has established itself as a leader in skin tightening treatments. However, the introduction of 10THERMA, a novel monopolar RF device, offers similar efficacy with advanced features such as smart temperature cooling (STC) and an auto impedance matching system, which enhance safety and comfort during procedures. A prospective split-face study comparing 10THERMA and Thermage FLXⓇ demonstrated comparable results in terms of wrinkle reduction and pigmentation improvement post-treatment.
These findings highlight the growing role of monopolar RF in comprehensive anti-aging treatments, not only addressing skin laxity but also improving age-related hyperpigmentation. As clinical evidence continues to support the safety and efficacy of monopolar RF devices, their use is expected to expand in dermatological practices.

XERF : New Dual frequency RF with ability of treatment depth control

Recently, the hottest area of EBD seems to be tightening using monopolar RF.
Considering the reason why monopolar RF treatment is in the spotlight, it is because less energy is delivered to fat cells due to the characteristics of monopolar RF, and electricity flows mainly to the dermis and fibrous tissue, so there is little possibility of a decrease in facial fat. And we can expect dermal and subdermal tightening.
The XERF is a new monopolar RF device with a frequency of 2Mhz along with the existing monopolar RF frequency of 6.78 Mhz. In addition, the area of the disposable effector (called a tip by other companies) in contact with the skin is 2x3 cm, which is about 50% larger than other monopolar RF devices, and it is equipped with a powerful cooling system, which has the advantage of reaching energy to a deeper layer than the existing monopolar RF equipment, and as a result, the improvement effect of face shape is more pronounced than that of conventional monopolar RF.
In addition, pain is dramatically reduced because the unique pulse configuration allows for more efficient energy transfer, and it has a powerful cooling system.
In this lecture, I would like to talk about clinical applications based on these contents.

The art of thermage FLX: Key strategies for maximizing outcomes

The Art of Thermage FLX: Key Strategies for Maximizing Outcomes

Facial aging involves complex changes across skin layers and deeper structures, resulting in decreased elasticity, wrinkles, and skin sagging. Non-surgical skin lifting and tightening procedures are increasingly favored for their safety, effectiveness, and minimal downtime. Monopolar capacitive-coupled radiofrequency (RF), approved in 2002 for wrinkle treatment, holds a pivotal position in noninvasive facial rejuvenation. This technology generates heat where electrical current passes, causing volumetric heating of the dermal tissue when the epidermis is cooled. Tissue temperature significantly affects impedance; as temperature rises, impedance lowers, allowing greater electrical flow and increased heat production in the tissue. Consequently, collagen fibers undergo degeneration and contraction, leading to new collagen formation and tissue tightening. In this lecture, I will focus on Thermage FLX, the hallmark of monopolar capacitive-coupled radiofrequency. Specifically, I will highlight my thoughts on maximizing the effects of Thermage FLX.
