Ultherapy Prime
Ultherapy Prime applies the latest HIFU (high-intensity focused ultrasound) technology to deliver the proven lifting effect of Ultherapy with even greater precision and safety.
DetailsDensity Noir is the newest model in the Density line, with a refined cooling system (DCD) that reduces pain and heat sensation during treatment. It includes a "Gentle Mode" that adjusts tip depth for softer treatment, and an "Infinity Mode" that delivers energy in a continuous, even stream — together supporting skin elasticity and collagen production.

Density Noir
Effects & advantages
Energy delivered to the fat and fascia layers creates thermal coagulation points that activate collagen and elastin, improving elasticity.
Energy in the epidermis and dermis evens out skin tone and improves texture flaws like wrinkles and freckles.
5 stage cooling
5-stage cooling means a quick return to daily life after a short session.
Real-time impedance feedback measures skin resistance to deliver the right amount of energy.
Is it for you?
RF energy delivered to the epidermis and dermis evens out skin tone and improves texture flaws like wrinkles and freckles. Energy delivered deeper, to the fat and fascia layers, creates thermal coagulation points that activate collagen and elastin production, improving elasticity. Two tip options let your doctor treat different facial areas for comprehensive contouring and lifting.
How it helps
Loose, sagging skin
Reduces sagging and improves elasticity by stimulating collagen.
The principle, in plain words
Density Noir sends radiofrequency energy deep into the skin. The heat makes collagen contract, and your skin then makes new collagen.
6.78 MHz monopolar radiofrequency energy is delivered deep into the skin, causing collagen fibers to denature and contract, which stimulates new collagen production and smooths wrinkles. This improves elasticity and reduces sagging. Each shot delivers 5 monopolar pulses, with cooling gas released on the second and fourth pulses to reduce skin irritation.

What makes it different
Side by side
Each treatment at Boost works in a different way, so the right one depends on your concern. Here is a simple side-by-side; Dr. Lee helps you choose after a 1:1 consultation.
| Treatment | Technology | Best for | Procedure | Downtime | Interval |
|---|---|---|---|---|---|
| Density Noir This page | Monopolar radiofrequency (RF) | Mild sagging, dull texture and enlarged pores, with a short session | 15–20 minutes | None — same day | Every 1–3 months |
| Ultherapy Prime | Focused ultrasound (HIFU) | Sagging skin and a softer jawline, with no downtime | 30–90 minutes | None — same day | 300 shots every 3–6 months; 600 shots every 6+ months |
| Thermage FLX | Radiofrequency (RF) | Loose skin, fine lines and lost elasticity, without surgery | 30 minutes | None — same day | Every 6–12 months |
| XERF | Radiofrequency (RF) | Sagging cheeks, double chin and lost elasticity, without surgery | 15–30 minutes | 2–3 days | Every 4 weeks |

Adds volumeDensity Noir works on elasticity and collagen. Juvelook Volume is built for areas that need real volume, like nasolabial folds and deep wrinkles.
Skin qualityRejuran works on the epidermis and dermis directly to improve fine lines, pores and moisture balance.
These are common ways to build a plan around one treatment. Your own combination, order and timing are set by Dr. Wangjin Lee after a 1:1 consultation.

Pricing overviewThe procedure takes about 15–20 minutes. The visit follows these steps: Consultation, Numbing cream applied, Density Noir procedure, Finishing soothing care.
The recommended interval is Every 1–3 months.
None — same day.
Washing and makeup are fine starting the day after treatment — avoid peeling treatments and exfoliating products. Mild temporary swelling, warmth, or redness can occur but resolve within a few days. Regenerating cream and moisturizer can help with warmth and dryness from treatment.

Details
Thermage FLX uses radiofrequency heat energy to smooth and firm the skin's surface and dermis, and is one of the strongest non-surgical skin-tightening treatments available.
Details
XERF Lifting uses radiofrequency energy to reach deep layers of the skin, stimulating collagen production in a non-invasive lifting treatment.
