Non-Surgical Skin Lifting and Collagen Stimulation
HIFU, also known as High-Intensity Focused Ultrasound, is a non-invasive treatment used to improve mild to moderate skin laxity, facial sagging and early signs of ageing.
At Skin and Scar Care Clinic, HIFU may be considered for patients who want a subtle, natural-looking lift without needles, surgery or significant downtime. It works by delivering focused ultrasound energy beneath the skin to create controlled heating at specific depths. This stimulates the body’s natural collagen response and gradually helps the skin feel firmer, tighter and more lifted.
HIFU is best suited to patients with early to moderate skin laxity. It is not designed to replace surgery, and it is not the strongest option for heavy jowls, significant neck laxity, loose abdominal skin or larger fat pockets. In those cases, alternative treatments such as Endolift, laser resurfacing, injectables or surgical options may be more suitable.
HIFU stands for High-Intensity Focused Ultrasound.
It uses ultrasound energy to target deeper layers of the skin without cutting or damaging the surface. The focused energy creates controlled heating beneath the skin, which encourages collagen contraction and new collagen production.
Collagen is the support protein that helps skin remain firm, lifted and elastic. As we age, collagen naturally reduces, which can lead to:
- Looser skin
- Early jowls
- Softer jawline
- Fine lines
- Skin thinning
- Mild neck laxity
- Under-chin looseness
- Reduced facial definition
HIFU aims to gently stimulate the skin’s own repair process for gradual tightening and lifting.
How Does HIFU Work?
HIFU works by delivering focused ultrasound energy to selected depths under the skin. The energy creates small thermal points beneath the surface, which encourages the tissues to tighten and remodel.
This process may help:
- Contract existing collagen
- Stimulate new collagen formation
- Improve skin firmness
- Support mild lifting
- Improve facial definition
- Tighten early laxity
- Improve the appearance of fine lines
The skin surface is usually left intact, which means there is minimal downtime for most patients.
What Areas Can HIFU Treat?
HIFU may be used on suitable patients for:
- Forehead and brow area
- Mild brow heaviness
- Cheeks
- Lower face
- Jawline
- Early jowls
- Under-chin area
- Neck
- Décolletage
- Mild body skin laxity in selected areas
The most common treatment areas are the lower face, jawline, under chin and neck.
Indications for HIFU
HIFU may be suitable if you have:
- Mild to moderate skin laxity
- Early jowling
- Softening of the jawline
- Mild under-chin looseness
- Early neck laxity
- Mild brow heaviness
- Fine lines on the décolletage
- Mild skin crepiness
- Early collagen loss
- Good skin quality but reduced firmness
- Preference for a non-invasive treatment
- No desire for needles, surgery or downtime
It is often chosen by patients who want a natural-looking improvement rather than a dramatic change.
Who Is the Best Candidate for HIFU?
The best HIFU candidates usually have:
- Early signs of ageing
- Mild to moderate sagging
- Reasonably good skin thickness
- Realistic expectations
- No major excess skin
- No significant fat heaviness in the treatment area
- Good general health
- Commitment to maintenance
HIFU is usually most effective when the skin still has enough collagen and elasticity to respond well.
Benefits of HIFU
Non-Invasive Treatment
HIFU does not involve surgical cuts, stitches or cannulas. It is performed externally over the skin.
No Needles or Filler
HIFU does not require injectable filler. It works by stimulating your own collagen.
Minimal Downtime
Most patients can return to normal activities soon after treatment.
Natural-Looking Results
Results develop gradually, so the improvement looks subtle and natural.
Collagen Stimulation
HIFU encourages the skin to produce new collagen, which may improve firmness and elasticity over time.
Skin Tightening and Lifting
It may help lift and tighten mild to moderate laxity around the face, jawline and neck.
Useful Preventative Treatment
HIFU can be helpful for patients in the early stages of ageing who want to maintain firmness before laxity becomes advanced.
Can Be Combined With Other Treatments
HIFU may be combined with skincare, injectables, skin boosters, laser resurfacing or other collagen-stimulating treatments depending on the patient’s goals.
What Results Can You Expect?
HIFU results are gradual.
Some patients notice a slight tightening effect soon after treatment, but the main improvement usually develops over several months as new collagen forms.
Possible improvements include:
- Firmer skin
- Sharper jawline
- Mild lifting of jowls
- Improved under-chin tightness
- Better neck definition
- Softer fine lines
- Improved skin elasticity
- More refreshed appearance
Results vary from person to person. Age, skin quality, degree of laxity, lifestyle, weight changes, sun damage and collagen response all affect the outcome.
Limitations of HIFU
HIFU is a useful treatment, but it has important limitations.
It is not the best option for everyone.
HIFU may have limited results if you have:
- Significant skin laxity
- Heavy jowls
- Advanced neck sagging
- Large under-chin fat pocket
- Loose abdominal skin after pregnancy or weight loss
- Severe sun damage
- Very thin skin with poor collagen reserve
- Marked volume loss
- Deep folds caused by facial fat loss
- Significant muscle or structural descent
- Unrealistic expectations
HIFU is not a substitute for:
- Facelift surgery
- Neck lift surgery
- Blepharoplasty
- Liposuction
- Abdominoplasty
- Endolift in patients needing stronger tightening
- Dermal filler where volume replacement is required
HIFU works best for subtle lifting, collagen stimulation and early laxity.
HIFU Contraindications
HIFU may not be suitable if you have:
- Pregnancy or breastfeeding
- Active infection in the treatment area

Precautions Before HIFU
Before treatment, please tell your practitioner if you have:
- Dental implants

These do not always mean treatment is impossible, but the plan may need to be adjusted.
How Many HIFU Sessions Are Needed?
Many patients have one main session, followed by review.
Some patients may benefit from:
- One session for mild laxity
- Two sessions for moderate laxity
- Maintenance every 9–18 months
- Combination with other treatments for best results
Estimated Number of Sessions by Age
These are general guidelines and may vary depending on skin quality, lifestyle and degree of laxity:
- Ages 25–35: Usually 1 session every 12–18 months for prevention and early collagen support
- Ages 35–45: 1–2 sessions initially, then maintenance every 9–12 months
- Ages 45–55: 2-3 sessions may be recommended for moderate laxity, followed by maintenance every 9–12 months
- Ages 55–65: 2–3 sessions may be needed depending on skin condition, with maintenance every 6–12 months
- Ages 65+: Results may be limited; 3-4 sessions may be considered, but alternative treatments such as Endolift or surgery are often more effective
If laxity is more advanced, Endolift or surgery may be discussed instead of repeating HIFU
Other Alternative Treatments
Depending on your concerns, alternatives may include:
Endolift
Best for stronger tightening and contouring of the lower face, neck, jawline, under chin, abdomen, arms or thighs.
CO₂ Laser
Useful when the main concern is surface ageing, fine lines, wrinkles, crepey skin or texture.
Erbium Glass Laser
Useful for collagen stimulation, mild tightening, skin texture, early scarring and overall skin quality.
Bio Remodelling / Bio Stimulator / Skin Boosters
Useful when the skin is dehydrated, crepey or losing elasticity.
Dermal Fillers
Useful when sagging is partly caused by volume loss in the cheeks, temples, jawline or chin.
Botulinum Toxin
Useful for dynamic lines, brow balance, neck bands or facial expression-related concerns.
Radiofrequency Microneedling
Useful for collagen stimulation, texture and mild tightening in suitable patients.
Surgery
Facelift, neck lift, blepharoplasty or abdominoplasty may be more suitable when there is significant loose skin or structural descent.

I am very happy that I finally found my doctor. Dr. Omer. The injections are done with perfect precision. Not a single bruise, not a single side effect. The clinic is in a very convenient location. The staff is friendly and attentive. Also, on the doctor's advice I had a HIFU procedure and it really works! In addition, it is quick and practically painless. The lifting effect is noticeable even after the first treatment. I can only imagine what happens after the second one. In general, my experience is as positive as possible. And the procedures are really effective and worth every penny. I am 43. Attaching a photo of me with no make-up no filters.
