Ultrasound-based lifting devices
Devices in this category, including well-known names like Ultherapy and various HIFU (high-intensity focused ultrasound) systems, work by delivering focused ultrasound energy to deeper skin layers to stimulate collagen production over time. These are generally marketed for gradual lifting and firming rather than a dramatic, immediate change, with results typically appearing gradually over the following weeks to months as collagen remodels.
Radiofrequency-based devices
Devices like InMode and various radiofrequency microneedling systems use electrical energy to heat tissue and stimulate a similar collagen response, sometimes combined with microneedling to deliver the energy more precisely into targeted skin depths. Shurink and similar Korean-market ultrasound devices sit closer to the Ultherapy category conceptually, though specific settings, depth and energy delivery vary by device and by clinic protocol -- these details matter more for outcome than the brand name itself.
Questions worth bringing to your consultation
- Which specific device and setting do you recommend for my skin type and concern, and why this one over the alternatives?
- What's a realistic timeline for seeing results, and how many sessions does this typically take?
- What's the expected downtime, and does it affect my flight timing?
- Can you show me before-and-after examples from patients with a similar concern to mine?
Asking these questions directly of a licensed provider will tell you far more than comparing device names in the abstract, since the same device used differently can produce very different results.
It also helps to ask how a specific clinic measures results over time -- some use standardized photography under consistent lighting at follow-up visits, which gives you a more objective before-and-after comparison than casual phone photos taken under different conditions each time.
