New Skin Tightening Devices Used in Korea
Here’s a current overview of the most advanced skin-tightening devices and technologies commonly used in Korea (2025–2026), especially in dermatology and medical aesthetic clinics. These focus on non-surgical tightening, collagen stimulation, and lifting—ranging from professional in-clinic machines to high-tech innovations gaining popularity1. Thermage FLX (Radiofrequency – RF)
- One of the leading RF skin-tightening devices used widely in Korea.
- Heats deep dermal layers to contract collagen and stimulate new collagen formation, improving firmness and texture.
- Non-invasive with minimal downtime.
2. Ultherapy / Ulthera / Ulthera Prime (Focused Ultrasound – HIFU)
- Uses micro-focused ultrasound to target the SMAS layer (same layer treated in surgical facelifts) without incisions.
- Particularly popular for jawline, neck, brow, and full-face tightening.
- Upgraded versions like Ultherapy Prime or clinic-customized combos (e.g., Ultherti) enhance precision.
3. XERF (Multifrequency RF Skin Tightening)
- A next-generation RF device gaining traction in Korea before spreading internationally.
- Uses multiple RF frequencies in one treatment for deeper, layered collagen remodeling with cooling technology for comfort.
- Effective for tightening face, neck, and body areas.
4. Sofwave (Synchronous Ultrasound Parallel Beam)
- Non-invasive ultrasound tightening device that stimulates collagen without damaging the epidermis.
- Known for consistent results and minimal downtime.
- Widely used in Korean clinics alongside Ultherapy.
5. RF Needling / Microneedle RF Devices
- Combines radiofrequency energy with microneedles to deliver heat deeper into dermal layers in a controlled way.
- Promotes collagen and elastin production while improving texture, fine lines, and laxity.
- Examples include devices similar to Potenza or Morpheus8 types seen globally.
6. Density / DENSITY Lifting (Advanced RF Rejuvenation)
- Korea-market device focused on high-frequency RF energy to remodel collagen deep in the skin.
- Effective for tightening and smoothing overall skin texture.
7. Titanium/Triple-Wavelength Lifting Lasers
- Uses multiple laser wavelengths (e.g., 755 nm, 810 nm, 1064 nm) for deep penetration and collagen induction, often paired with micro- or macro-cooling.
- Offers tightening, complexion improvement, and lifting effects with reduced discomfort.
8. Clinic-Customized Hybrid Protocols (e.g., “Ultherti” / Combined Systems)
- Some Korean clinics blend multiple technologies—RF + ultrasound + laser—to maximize tightening and lifting tailored to individual facial structures.
- While not a single device, these protocol combinations represent cutting-edge practice in Korea.
9. At-Home & Consumer Devices (Growing Trend)
While not as powerful as professional clinical machines, several high-tech at-home tools are gaining popularity and bridging the gap:
- Dual RF + EMS devices (e.g., LG Pra.L Dual Lifting) for muscle toning + collagen stimulation.
- High-tech microcurrent + LED devices for improved elasticity and mild tightening.

Trends in Korea’s Skin Tightening Market (2025–2026)
- Shift to multifrequency RF and combination modalities for richer collagen stimulation and deeper penetration.
- Rise of clinic-customized protocols that blend technologies based on individual skin needs.
- Growth in AI-supported and at-home tightening devices, enhancing personalization and accessibility.
