6 to 24 months, depending on the device: Shurink Universe HIFU is typically refreshed every 6-12 months, Ultherapy Prime HIFU holds 12-18 months, and Thermage FLX monopolar RF runs 12-24 months — from ₩149,000 (≈ $106) per session at Kind Global Clinic Myeongdong, where a co-director maps your refresh cycle in writing.
First, an honesty note that most clinic pages skip: "laser lifting" is the colloquial umbrella term Korean clinics use for non-surgical, energy-based lifting — but the machines behind the name are not literal lasers. They are focused ultrasound (HIFU) platforms such as Shurink Universe and Ultherapy Prime, and radiofrequency (RF) platforms such as Thermage FLX, Oligio X and Density. That distinction is exactly why "how long does laser lifting last" has no single answer — each energy type builds and loses collagen on a different clock.
The common biology: both HIFU and RF heat targeted tissue layers to trigger collagen contraction and then months of new collagen remodeling. Results peak at month 2-3, hold on a plateau, and fade gradually as natural aging resumes — the machine does not wear off overnight like a filler dissolving. Korean HIFU data shows skin elasticity significantly improved at 12 weeks (Ko EJ 2017, 32 Korean subjects), Asian monopolar RF data shows graded improvement sustained through 6-month follow-up (Wanitphakdeedecha 2022), and objective moire topography shows perioral laxity reduction persisting through 24 weeks after a single monopolar RF session (Suh 2021).
At Kind Global Clinic Myeongdong, the duration question is answered per face, not per brochure: a co-director — Dr. Lee Wonjin (KR Medical License 143124) or Dr. Lee Kangin (KR Medical License 141247) — assesses your laxity grade, age band and prior treatment history at a 15-20 minute consultation, then writes your expected duration and refresh date into the plan. Published per-session pricing runs from ₩149,000 (≈ $106) for Shurink Universe 300 shots to ₩1,990,000 (≈ $1,421) for Thermage FLX 600 shots — the same KRW figures for Korean and international patients, typically 50-70% below comparable US and Japan pricing.
