Liftera-V recognized by Korea's KFDA, this painless and non-invasive lifting and tightening device utilizes TDT Hot Spot Diffusion Technology combined with high-intensity focused ultrasound (HIFU). It delivers vortex-like energy directly to the dermis and SMAS fascia layer, embedding invisible energy lines into the dermis and fascia. This achieves an instant lifting effect while stimulating collagen regeneration and remodeling, tightening sagging areas, and redefining firm contours.
