HIFU Skin Tightening

High-intensity focused ultrasound (HIFU) at Dr Plus Aesthetics Clinic penetrates to the deep fascia layer of the skin to contract tissue and stimulate collagen production, delivering a non-surgical lift to the forehead, cheeks, jawline, jowls, and neck.

HIFU (High-Intensity Focused Ultrasound) is one of the most technically advanced non-invasive skin tightening modalities available, and a central offering at Dr Plus Aesthetics Clinic. The treatment uses focused ultrasound energy to target the SMAS layer — the same tissue layer addressed during surgical facelifts — creating precise thermal coagulation points that trigger a collagen remodelling response deep beneath the skin's surface. Unlike radiofrequency devices that heat the superficial dermis, HIFU bypasses the outer skin layers entirely and delivers energy at precise depths of 1.5mm, 3.0mm, and 4.5mm. This depth control allows the treatment to address skin laxity at the dermis, sub-dermis, and SMAS levels simultaneously, producing a natural lifting effect on the forehead, brow, cheeks, jowls, jawline, and neck. At Dr Plus Aesthetics Clinic, the HIFU protocol is customised to each patient's facial anatomy. Dr Kenneth Lee maps the treatment zones prior to the session and selects the appropriate transducer depth based on tissue thickness and the degree of laxity present. Patients with mild-to-moderate skin laxity typically see the most dramatic improvements, though the treatment is beneficial across a range of ages and skin conditions. The procedure takes 45–90 minutes depending on the treatment area. A mild tingling or sharp heat sensation is felt during energy delivery at each coagulation point — this is a sign that the ultrasound is reaching the targeted depth. Topical anaesthetic or analgesics may be offered to improve comfort. There is no downtime; mild redness or tingling may persist for a few hours post-treatment. Collagen remodelling following HIFU is a gradual process. Patients typically notice initial tightening within the first few weeks, with peak results appearing at 3–6 months as new collagen fully matures. A second session 3 months after the first is recommended for an additive benefit, with maintenance every 12–18 months thereafter.
