What Is HIFU (Ultherapy)?
HIFU (High-Intensity Focused Ultrasound) is a non-invasive skin tightening technology that uses focused ultrasound energy to precisely heat the deep SMAS layer and dermis, stimulating collagen remodeling and production for a lifting and tightening effect.
Rappoel Dermatology Clinic uses American Ultherapy—the most widely used HIFU system globally, certified by both the US FDA and Korean KFDA.
The key advantage of American Ultherapy over other HIFU devices is its “real-time ultrasound imaging”—the practitioner can see skin layers on screen during treatment, precisely controlling energy depth for enhanced safety and accuracy.
HIFU vs Thermage: Key Differences
- Technology: HIFU uses focused ultrasound; Thermage uses radiofrequency (RF)
- Depth: HIFU reaches the SMAS layer (4.5mm); Thermage primarily targets the dermis (2.5-3.0mm)
- Pain Level: HIFU causes more discomfort near bone areas (chin, forehead); Thermage has more surface heat sensation
- Onset: HIFU shows some immediate tightening; Thermage results are more gradual
- Duration: Both last approximately 1-2 years
- Best For: HIFU for significant sagging; Thermage for skin laxity and texture concerns
Who Is a Good Candidate for HIFU?
- Ages 30-60 with noticeable facial sagging
- Undefined jawline, double chin, or sagging cheeks
- Those wanting near-surgical lifting results without incisions
- Anyone who can tolerate moderate discomfort
- People wanting visible improvement from a single session
The Rappoel Ultherapy Process
1. Skin Assessment: The director evaluates the degree of sagging, laxity, and target areas to confirm suitability.
2. Cleansing & Marking: After cleansing, the director maps treatment zones with marking lines.
3. Treatment: Gel is applied and the Ultherapy handpiece delivers focused ultrasound energy across marked areas. Full-face treatment takes 60-90 minutes.
4. Post-Care: Mild redness and swelling may occur. Ice packs are applied before you leave, along with detailed aftercare instructions.
When Will I See Best Results?
HIFU results are progressive: you’ll feel mild firmness immediately, visible improvement appears around 3 months, and peak results are reached at 6 months as collagen remodeling completes. Results last 1-2 years, with annual maintenance sessions recommended.
