Thread Lift vs. HIFU vs. RF: Which Works Best for Sagging?! An Honest Review Including Cost-Effectiveness!!
Many people probably find themselves thinking, “I’m concerned about sagging, but I don’t know whether a thread lift, HIFU, or RF is best for me…” There are many types of lifting treatments, each with different pros and cons.
This time, we thoroughly compare which treatment is most effective for sagging, including cost-effectiveness. This is an honest, no-holds-barred review, so please use it as a reference when choosing your treatment!
1. A Quick Review of the Basics of Sagging Treatments
Sagging treatments can be broadly divided into three approaches.
①Thread Lift → Physically lifts the skin
②HIFU → Uses ultrasound to tighten from the skin’s foundation
③RF (Radiofrequency) → Uses heat to increase and coagulate collagen, gradually tightening the skin
All of these treatments are effective for improving sagging, but they differ in terms of “immediacy,” “how long the effect lasts,” “downtime,” and “cost-effectiveness.”
2. Thread Lift
【Features】
✔︎Threads are inserted under the skin to physically lift it
✔︎Promotes collagen production until the threads dissolve, with no adverse effect from the threads themselves
✔︎The strength of the effect varies depending on the type of thread used
【Pros】
○ Since it physically lifts the sagging skin, the effect is immediate
○ Collagen is generated around the thread lift
○ Produces a noticeable change
【Cons】
✖ There is downtime (risk of swelling, bruising, and pain)
✖ A sense of discomfort remains until the threads dissolve
✖ The lifting effect fades sooner than you might expect (the threads themselves are absorbed over 1 to 1.5 years)
✖ The price is on the higher side (typically ¥100,000 or more)
【Recommended For】
Those who can afford a certain level of cost
Those who want immediate results
Those who are quite concerned about sagging
3. HIFU
【Features】
✔︎ Uses ultrasound to apply heat deep in the skin (the SMAS fascia layer) to lift it
✔︎ Improves sagging by tightening the skin’s foundation
【Pros】
✔ Since it lifts from the skin’s foundation, it produces a natural tightening effect
✔ Almost no downtime (some redness may occur but subsides quickly)
✔ Peaks 1–2 months after treatment rather than immediately, with lasting results
【Cons】
✖ Not as immediate as a thread lift (takes time for the effect to appear)
✖ Results can vary depending on the practitioner’s skill, and the SMAS fascia layer differs from person to person
✖ There is a risk of burns
【Recommended For】
Those seeking a lift without surgery
Those who want treatment with no downtime
Those who want to keep the per-session cost down while receiving regular care
4. RF (Radiofrequency)
【Features】
✔︎ Uses radiofrequency waves to warm the deep layers of the skin, increasing collagen and lifting the skin
✔︎ Low pain, yet you can feel the effect right after treatment
【Pros】
✔ The heat increases and coagulates collagen, giving a noticeable tightening effect
✔ Almost no downtime
✔ Low pain makes it easy even for first-timers
✔ Relatively affordable pricing (around ¥30,000 per session)
【Cons】
✖ Change from a single session is limited, and regular visits are required
✖ If sagging has progressed significantly, a dramatic lift is difficult
【Recommended For】
Those who want to maintain their current condition while getting even a small lift
Those who want to boost skin firmness
Those who dislike pain and want an easy treatment to receive
5. Which One Works Best for Sagging? An Honest Rating!
| Thread Lift | HIFU | RF | |
|---|---|---|---|
| Immediacy | ◎ (Immediate results) | △ (Effect after 1–2 months) | ○ (Both immediate and after 1–2 months) |
| Duration | 6 months–1 year (until threads dissolve) | 3–6 months | 1–3 months |
| Pain | × (Some pain) | △ (Some heat sensation) | ◎ (Almost none) |
| Downtime | × (Possible swelling/bruising) | ◎ (Almost none) | ◎ (Almost none) |
| Cost-Effectiveness (Per Session) | × (¥100,000+) | ○ (¥30,000–100,000) | ○ (¥30,000–100,000) |
| Recommendation | ★★☆☆☆ | ★★★☆☆ | ★★★★☆ |
In conclusion, we recommend “Thread Lift” if you want immediate results, “HIFU” for a natural tightening effect, and “RF” if you dislike pain and want maintenance-style treatment while still seeking both immediacy and lasting results.
6. Which Should You Choose If Cost-Effectiveness Is Your Priority?
In terms of cost-effectiveness, thread lifts are simply too poor a value. We recommend deciding to get one just once a year.
One thing to note about thread lifts is that, while you’re often told before treatment that it lasts about a year, this refers strictly to the time it takes for the threads themselves to dissolve — in reality, many people find that the lifting effect peaks right after treatment through about one month, and then gradually starts to fade from around two months onward.
For a recommended thread lift schedule, getting the treatment 3 weeks to 1 month before an important occasion, and then maintaining the lifted state afterward with HIFU or RF, lets you keep the effect as long as possible — so we recommend combining treatments!
If you’re not considering threads, receiving RF regularly and occasionally adding HIFU lets you care for both the foundation and the dermis layer, making your skin more resistant to sagging and keeping it firmer. A schedule of once every 3 months or so, about 3 times a year, should be sufficient.
7. Summary | Choose the Best Treatment for Improving Sagging!
In conclusion, thread lifts are the most effective treatment for sagging, but since their cost-effectiveness is poor, if you’re not seeking immediate or dramatic change, HIFU or RF treatments can achieve a sufficient lifting effect!
✔ If you want immediate results → Thread Lift
✔ If you want a natural lift → HIFU
✔ If you want pain-free, easy care → RF
Choose the treatment that’s right for you based on how far your sagging has progressed and your budget!
