Thermage FLX vs. Density Lifting: How to Choose the Right RF Treatment for You
We compare and analyze Thermage FLX and Density, the leading radiofrequency (RF) lifting treatments for improving skin elasticity that declines with age. We guide you through each device's energy delivery method, expected changes, and the importance of establishing a personalized lifting plan through the Mark-Vu precision diagnostic system.
The Core of Skin Elasticity: RF Lifting for Collagen Regeneration
As we age, the collagen in our skin decreases, leading to a loss of elasticity and natural changes such as wrinkles and sagging cheeks. Since cosmetics or massages that only treat the skin's surface have limitations, a procedure that delivers energy deep into the skin to improve its fundamental environment is necessary.
A representative method is Radio Frequency (RF) lifting. Among them, we will look closely at 'Thermage FLX,' which is trusted worldwide, and 'Density' lifting, which has recently been gaining attention.
When is RF Lifting Needed?
Although skin aging appears differently for each individual, common concerns where RF lifting is recommended include the following:
- When the cheeks or jawline sag, causing concerns about a double chin
- When nasolabial folds deepen, making the facial expression look gloomy
- When overall skin elasticity drops, leading to a loss of volume across the entire face
- When you want natural, non-artificial lifting results
4th Generation Thermage FLX: The Standard of Powerful Monopolar RF
One step more advanced than the 3rd generation Thermage (CPT), Thermage FLX is a procedure that uses Monopolar RF to deliver energy deep into the dermal layer of the skin.
The thermal energy induces the denaturation and contraction of collagen to refine facial contours, and in the long term, it helps generate new collagen to make the skin firm. Additionally, it features a built-in continuous cooling system that reduces the burden of pain and skin surface damage that may occur during the procedure.
Density Lifting: The Dual Action of Monopolar and Bipolar RF
Density is a hybrid lifting method where Monopolar and Bipolar RF work together. It has the advantage of delivering energy broadly, not only to the deep layers of the skin but also to the layers closer to the surface.
The energy delivered in this way helps to firmly tighten sagging skin and improve fine lines. It is an excellent alternative, especially when you want to simultaneously address wrinkles in delicate, thin-skinned areas like around the eyes or mouth, as well as double chin concerns.
Thermage FLX vs. Density: Comparison Points
| Category | Thermage FLX | Density |
|---|---|---|
| Energy Method | Monopolar RF | Monopolar + Bipolar RF |
| Main Target | Deep dermal elasticity enhancement | Three-dimensional elasticity across all skin layers |
| Features | The gold standard of RF lifting | Simultaneous improvement of fine wrinkles and volume |
| Cooling System | Gas cooling method | Gas cooling method |
1:1 Custom Design Engineered with Mark-Vu Precision Diagnostics
Because each individual's skin thickness and aging progression are different, 345 Skin Clinic utilizes the 'Mark-Vu' skin diagnostic system before the procedure. By precisely measuring 12 categories, including pores, wrinkles, and skin tone, we identify even the invisible problems deep within the skin.
Beyond simply using the equipment, our experienced medical staff analyzes your facial structure to proceed with a 1:1 customized design. We increase the reliability of our procedures by strictly adhering to the principles of using genuine tips and exact shot counts.
The speed of skin aging can be significantly slowed down depending on how you manage it. We hope you maintain healthy and elastic skin through RF lifting optimized for your specific skin type.
Frequently Asked Questions
What skin concerns are effectively treated by high-frequency lifting?
Yes, it is effective in improving double chin, nasolabial folds, and overall loss of elasticity. High-frequency energy is delivered deep into the skin to help regenerate collagen, so it is recommended for those who desire a natural, non-artificial lifting effect.
What is the biggest difference between Thermage FLX and Densithy Lifting?
The biggest difference lies in the energy delivery method. Thermage FLX uses monopolar radiofrequency to strengthen elasticity deep in the dermal layer, while Densithy uses both monopolar and bipolar radiofrequency to improve the three-dimensional elasticity of all skin layers.
Which treatment is suitable for improving fine wrinkles around the eyes or mouth?
Densithy Lifting can be a good alternative. Densithy broadly delivers energy to layers closer to the surface, helping to improve fine wrinkles around the thin and delicate eye and mouth areas.
How is skin diagnosis performed before the procedure?
It is precisely performed using the Mark-Vu system. After measuring 12 items such as pores, wrinkles, and skin tone to identify even invisible problems within the skin, experienced medical staff establish a 1:1 customized design.
Is high-frequency lifting painful?
The pain burden can be significantly reduced through the cooling system built into the equipment. Both Thermage FLX and Densithy adopt a gas cooling method, which alleviates pain and skin surface damage that may occur during the procedure.
