This is a procedure note for Abdominal Fat: Is Onda Lifting or Fat-Dissolving Injections Better? Delving into Injection Mechanisms at Beomgye(Opening Soon) KKEUT Korean Clinic.
We will explore the distinctions between abdominal fat-dissolving injections and abdominal ONDA lifting. This will be achieved by understanding the fundamental principles behind fat-dissolving injections.

Q. Is all fat in the abdominal area situated in a single layer?
Not at all. The majority of fat that is easily palpable consists of accumulations within the subcutaneous fat layer.
Visceral fat, located among the organs inside the abdominal cavity, cannot be grasped externally, and
it is not directly addressed by injections or devices designed for fat reduction.
Noticeable improvements in persistent fat generally begin with a decrease in the thickness and spread of subcutaneous fat deposits.

Q. Which key components are typically found in fat-dissolving injections?
Fat-dissolving injections are known by various names across different clinics, yet the primary substance frequently utilized for abdominal procedures is
DCA (Deoxycholic Acid).
DCA, a form of bile acid, influences the phospholipid layer of fat cell membranes,
aiding the body's natural processes where fat cells undergo breakdown and subsequent absorption via the immune system, lymphatic pathways, and bloodstream.

Q. How does Deoxycholic Acid contribute to fat reduction?
When DCA is introduced into the fat layer, it spreads towards the core of the fat accumulations, and
it stimulates the membranes of fat cells, initiating a process termed adipocytolysis (the breakdown of cells).
Triglycerides stored within these cells are broken down into glycerol and fatty acids, which are subsequently released from the cells, and
residual cellular fragments are then removed by macrophages as part of the body's immune response.
Subsequently, these fatty acids and glycerol are transported through the lymphatic system and microcirculation to the liver, where they enter energy metabolic pathways for further processing.
Consequently, the height and width of the fat deposits may diminish, potentially leading to a more defined silhouette due to a reduction in overall volume.

Q. What type of technology is used in Abdominal ONDA Lifting?
Although various medical devices are employed for fat management treatments,
ONDA (utilizing DEKA's 2.45GHz microwave, with integrated contact cooling) is one notable option often used for abdominal contouring.
This particular device avoids electrical current stimulation on the skin's surface; instead, its electromagnetic waves directly cause water molecules within the subcutaneous fat layer to vibrate,
leading to a temperature increase in the fat layer through a Joule heating reaction. This process influences local environmental conditions that may encourage fat release and subsequent absorption.

Q. Does ONDA technology eliminate fat cells or merely reduce their individual volume?
This device neither incises fat nor causes immediate physical destruction of tissue.
Its operational mechanism does not involve shrinking the size of individual fat cells either.
Instead, it orchestrates a progressive sequence of tissue alterations: commencing with an overall temperature elevation within the fat deposit, followed by the promotion of fat release, and then an acceleration of absorption through the lymphatic system and microcirculation.
This also leads to a connection with dermal collagen remodeling, ultimately resulting in
a potential reduction in the total volume of the fat deposit.

Q. What is the typical timeline for observing the outcomes of each treatment?
For DCA injections, an initial reduction in skin firmness might be perceived within 3-7 days post-treatment, and
a decrease in the volume of the fat deposit typically becomes noticeable within 2-3 weeks, with
more significant, cumulative changes often becoming evident after 6 weeks.
ONDA lifting treatments commonly start to show improved contouring and enhanced skin elasticity around 1-2 weeks following the procedure, and
a noticeable reduction in the height of the fat deposit is generally observed by week 4,
with the full cumulative benefits frequently reaching their peak between weeks 8 and 12.

Q. What accounts for the observable distinctions between these treatments?
Injections offer the benefit of directly delivering medication to the fat layer, which encourages cell breakdown.
In contrast, devices distribute energy uniformly across a broader fat layer, leading to fat breakdown and potentially also stimulating collagen regeneration.
With injections, it is possible for variations in diffusion and localized tissue responses, such as bruising, nodules, or tenderness, to occur, making careful dose management essential.
For treatments using devices, delivering sufficient energy is crucial for expecting the desired outcome.

Q. What treatments are generally better suited for particular body shapes?
Should your aim be to reduce volume in specific areas where fat pads are clearly prominent, like the lower abdomen or love handles,
DCA injections could be a suitable option.
If your focus is on managing widely distributed fat across the entire abdomen, coupled with diminished skin elasticity, and working towards a smoother overall body contour,
ONDA treatment could be considered.

Q. Ultimately, what is a key criterion when selecting a treatment?
Simply selecting a procedure just because you have fat may lead to an outcome that doesn't align with your specific fat characteristics.
Therefore, a comprehensive assessment of factors such as fat layer thickness, the distribution of fat pads, skin elasticity, and the condition of lymphatic and microcirculation should be made.
This allows for effective utilization of the strengths of both injection and device-based treatments when making a selection.
Thus, rather than simply opting for any particular treatment just because you have persistent fat on your abdomen, arms, or thighs,
it is advisable to obtain an accurate diagnosis of your specific fat concerns and then, in consultation with a specialist, decide on the most suitable treatment approach.

Treatments that work especially well together.
