Thread Lift & Mini Facelift

Facial Laxity — Sagging Skin

Facial skin laxity and sagging occur when collagen depletes, supporting ligaments loosen, and facial fat descends with age, leading to deep nasolabial folds, sagging cheeks, and a double chin. Mild cases can be improved with HIFU or RF; moderate laxity is suitable for thread lifts; severe laxity with significant excess skin requires surgical facelift. A doctor will assess the degree of laxity to select the appropriate treatment level.

Why Does the Face Sag?

Aging occurs across three structural layers simultaneously: the skin loses collagen and elasticity; facial fat pads atrophy in the upper regions (temples, upper cheeks) and descend into the lower regions (nasolabial folds, double chin); and the retaining ligaments supporting the soft tissue become lax. As a result, the youthful heart-shaped facial contour gradually turns square, and the jawline loses its definition. Sun exposure, smoking, and rapid weight loss accelerate this process.

Three Degrees of Sagging, Three Treatment Approaches

Mild (ages 30–40, early loss of skin firmness, faint folds): Non-invasive collagen-stimulating technologies—HIFU, RF—provide moderate tightening improvements and require maintenance. Moderate (ages 40–55, pronounced folds, mild jowls, emerging double chin): Thread lifts reposition soft tissue to a higher anchor point, lasting 1–2 years, and can be combined with dermal fillers to restore volume. Severe (over 55 or with significant excess skin): Surgical rhytidectomy (facelift, mini facelift) excises redundant skin and resuspends deeper tissues—providing the longest-lasting outcome.

What Happens When the Wrong Treatment Level Is Chosen?

Performing a thread lift on skin with significant excess results in lifting that lasts only a few months, leaving the skin still loose and wasting financial investment. Using HIFU on noticeably sagging tissue yields imperceptible improvements. Conversely, performing surgery on mild, early-stage skin laxity is considered overtreatment. Choosing the correct intervention level is far more critical than simply opting for the 'newest' technology.

Why Is Simultaneous Volume Restoration Necessary?

Facial sagging coincides with fat atrophy in the upper facial regions; simply pulling the skin tight without restoring volume results in an unnatural, hollowed appearance. Physicians often combine treatments with fillers or fat grafting to the temples and upper cheeks when necessary to achieve a harmonious, natural look.

How BonBoz Approaches Your Care

Our physicians conduct in-person consultations to evaluate region-specific tissue laxity, skin thickness, facial fat volume, age, and individual aesthetic goals before recommending the appropriate treatment plan—even if the conclusion is 'no treatment is needed yet' or 'a thread lift is insufficient; surgery is recommended.' Plastic surgeons perform thread lifts and surgical procedures, while non-invasive HIFU/RF energy-based devices and dermal fillers are administered under non-surgical aesthetic medicine.

Severity levels

1

Mild — loss of firmness, fine lines

Typically ages 30–40. HIFU/RF to stimulate collagen, maintained periodically; moderate results.

2

Moderate — visible folds, mild cheek sagging, early double chin

Typically ages 40–55. Thread lift to elevate tissue, can be combined with volume restoration; lasts 1–2 years.

3

Severe — significant excess skin, undefined jawline

Typically over 55 or following major weight loss. Surgical facelift (mini facelift/facelift) — longest-lasting.

When should you see a doctor?

  • A poorly defined jawline and noticeable double chin, despite no change in weight.
  • You have had a thread lift, but the results lasted only a few months—the degree of laxity may have exceeded what threads can support.
  • You were recommended expensive treatments, but no one truly assessed your actual level of skin laxity.
  • More pronounced sagging on one side—requiring neurological causes to be ruled out.

How BonBoz treats it

Non-invasive HIFU facelift

High-Intensity Focused Ultrasound stimulates collagen in deep tissue layers — ideal for mild sagging, maintenance required.

Thread lift

Absorbable barbed threads reposition and lift soft tissue — suitable for moderate sagging, lasts 1–2 years.

Learn about this method →

Mini facelift / surgical facelift

Excises excess skin and redrapes underlying tissue — designed for severe sagging, delivers the longest-lasting results.

Learn about this method →

Volume restoration (fillers / fat grafting)

Restores volume to the temples and upper cheeks for a natural, non-hollow appearance.

Cost guidance

Costs increase with the invasiveness of the procedure: HIFU is priced per session/area, thread lifts per area, and surgery is the most expensive but offers the longest-lasting results. An estimated price range is available in our cost estimator tool; the exact quote will be provided by the doctor after your consultation.

The final price follows the doctor’s recommendation after an in-person exam. A confirmed quote has no hidden extras.

Frequently asked questions

How long does a thread lift last?

Typically 1–2 years, depending on the thread type, degree of skin laxity, and individual body response. As the threads gradually dissolve, newly stimulated collagen helps maintain part of the lifting effect.

Will a thread lift make my face look stiff or unnatural?

Your face may feel tight with minor dimpling or rippling during the first few weeks; after that, results look natural if the threads are placed along the correct vectors and in proper quantities. Stiffness only occurs when an excessive number of threads is used.

Is HIFU painful, and how often should it be repeated?

You may feel a warm, prickling sensation, which is well-tolerated. Results improve progressively over 2–3 months and last for 6–12 months before a repeat session is needed.

Does a facelift leave visible scars?

Incisions are concealed within the hairline and around the ears, fading over time. As this is a true surgical procedure, it requires a recovery period of 2–4 weeks.

What is the ideal age for a facelift?

Candidacy depends on the amount of excess skin rather than chronological age. Some individuals are suitable candidates at 50, while others at 60 can still achieve great results with a thread lift if their skin retains good elasticity.

Does Botox tighten the skin?

Botox relaxes targeted muscles to soften dynamic wrinkles and can refine the jawline, but it does not lift sagging tissue. Its mechanism is completely different from a thread lift.

Can facial sagging caused by rapid weight loss recover on its own?

Stretched skin rarely retracts completely on its own, especially after age 40. The degree of laxity will determine the most suitable treatment approach.

Can I get a thread lift after having HIFU?

Yes, and they often complement each other: HIFU tightens the skin, while threads lift the underlying tissues. Your doctor will determine the treatment sequence and the appropriate interval between sessions.

Is a thread lift dangerous?

It is a minimally invasive procedure. Potential risks include bruising, skin dimpling, visible thread ends, or asymmetry—all of which are minimized when performed by a qualified doctor in the correct tissue plane.

Who performs the procedures at BonBoz?

Thread lifts and surgical facelifts are performed by Dr. Nguyen Xuan Vu (MSc, Specialist Level II); HIFU and dermal fillers are administered by non-surgical aesthetic dermatologists.
