Ulthera SPT vs Thermage FLX — Bangkok skin tightening
Clinical Guide·5 min read·2026-04-02

Ulthera vs Thermage — which tightening is for me?

In one paragraph

Ulthera uses focused ultrasound at SMAS depth (1.5/3.0/4.5 mm); Thermage uses monopolar radiofrequency through the dermis. Ulthera lifts; Thermage tightens skin envelope. Most patients in their late thirties through fifties combine both. Bangkok: Ulthera SPT from ฿18,000 · Thermage FLX from ฿28,000.

01How each device works

Ulthera (micro-focused ultrasound) deposits coagulation points at three depths — 1.5, 3.0 and 4.5 mm — including the SMAS layer that surgeons address in a facelift. Thermage (monopolar RF) heats the dermis volumetrically.

Both stimulate collagen, but the depth and pattern of energy delivery are completely different.

02Who suits which

Patients with descent (jowls, brow heaviness) benefit from Ulthera's SMAS-depth lift. Patients with skin laxity and crepiness benefit from Thermage's dermal tightening.

Most patients in their forties have both concerns and benefit from sequential treatment.

03When to combine

Sequencing matters. We typically perform Ulthera first to address the structural lift, then Thermage 6–8 weeks later for envelope tightening. Combining in a single session is possible but tolerability is reduced.

04Bangkok pricing (2026)

Ulthera SPT from ฿18,000; Ulthera Prime (advanced protocol) from ฿45,000. Thermage FLX from ฿28,000. Combined pricing offered for sequential courses.

05Common questions

Can I do both in one session?+
Technically possible, but tolerability is reduced and we prefer sequential treatment 6–8 weeks apart.
Which gives faster results?+
Thermage gives slightly more immediate skin tightening at week 1; Ulthera builds over 3–6 months.
