Korean HIFU (Shurink, Ultraformer, Doublo)

Like Ultherapy, these focus ultrasound energy at set depths under the skin to contract tissue and stimulate collagen. Newer models (Shurink Universe, Ultraformer MPT) use faster, gentler pulses at lower energy, so clinics often repeat them more often.

Warm prickling and deep aching on bony areas, typically milder than Ultherapy, especially in 'comfort' modes.

How much downtime: Low — None to minimal: slight redness or tenderness for a day or two.

Cost for that downtime: $300–$1,500 per session (much cheaper in Korea), 1 session every 6–12 months.

Is it worth it? Our verdict (3/5): Better value than Ultherapy for mild results, but results are subtle and depend heavily on the operator. Insist on a genuine, named device.

• Subtle tightening of jawline and cheeks
• Lower price makes regular maintenance possible
• Little to no downtime

• Lift significant sagging
• Match surgery
• Treat pigmentation or scars

• Temporary swelling, tenderness or numbness
• Burns or fat loss if used aggressively or by poorly trained staff
• Cheap copy devices with unknown safety

Darker skin tones: Generally safe for darker skin because the energy bypasses the surface pigment.

Good fit

• Mild early sagging, often in the 30s–40s
• People who prefer regular, cheaper top-ups

Avoid or ask a doctor first

• Very thin or hollow faces
• Pregnancy
• Clinics that can't name the exact device and show that it's genuine

Typical cost: $300–$1,500 per session (much cheaper in Korea) (USD, varies by city and provider)

Sessions: 1 session every 6–12 months
