Face Lifting and Tightening Clinic in Samut Prakan–Bangna, by Dermatologists
Facial skin laxity is the loss of firmness in the skin and the tissue beneath it with age, sun exposure and weight changes, leaving the jawline less defined and the cheeks or under-chin sagging. Siam Dermatology, a dermatology specialty clinic, has doctors assess and perform facial lifting and tightening procedures. It is located on Thepharak Road, Mueang Samut Prakan, about 9.5 kilometres from Central Bangna, or roughly 12–15 minutes by car in normal traffic. Our team includes dermatologists such as Dr. Patara Voravutinon (medical licence no. 54323).
Sagging sits in a different layer for each person, and some types are not a job for a device at all. This page therefore answers only the location-based questions: where the clinic is, who assesses and performs the treatment, and which technology suits which problem. For general information on each layer of the skin, read Facial lifting and tightening: how to choose the right option for your type of sagging.

Which types of sagging should see a doctor
Age-related sagging is not a disease and not everyone needs treatment. See a doctor if any of the following applies to you
Your jawline is becoming less defined, most visible from the side or when you look down, and it has kept changing for more than 6–12 months.
Rapid weight loss followed by hollow cheeks or loose skin. The cause of the weight loss should be checked as well.
You have used creams for 3–6 months and feel it is not enough, and you want to know which layer the problem is in.
You have had a procedure but see no change, which may be because the method did not match the layer, not because you need more treatment.
You are not sure whether it is sagging or just dull skin, such as wrinkles, dark marks or enlarged pores, which are cared for differently.
If the change is sudden or on one side only, skip to the section “Sudden facial drooping or sagging on one side” first, because that is not a cosmetic matter.
What the doctor assesses before choosing a method
Before choosing a device, the doctor must be able to answer these 5 questions, because the answers change the whole plan.
Which layer is sagging? Thinning skin, the fibrous tissue that supports the face (SMAS), fat that has shifted down, or bone that has thinned with age.
How thick is the skin? This sets the depth and energy. Very thin skin or very little fat may not suit some methods.
Is there a lot of excess skin? If there is, energy-based procedures usually give limited results.
Are there any contraindications? Pregnancy, a pacemaker, a history of keloids, current medications, and any material previously injected or implanted in the face.
What do you expect? You need to agree clearly that the results of a procedure differ from surgery.
A sagging assessment should therefore not begin with “I want this device”. It should begin with looking at the whole face while sitting, facing forward and from the side, and taking photos from the same angles so you can compare them yourself later.
Early skin laxity with fine lines
What it looks like: The skin is thinner and rebounds slowly, with fine lines on the cheeks or around the mouth, but the jawline has not lost much shape. It usually starts to show in the 30s–40s.
Cause: Collagen in the dermis decreases with age, together with accumulated sun exposure.
Severity/urgency: Not urgent. Sun protection and topical medication are usually the first step. If a procedure is wanted, mid-depth ultrasound or radiofrequency is usually considered. For the basics, read Wrinkles and skin care to slow ageing.
When to see a doctor: When 3–6 months of self-care is still not enough, or when you are not sure the changes are really wrinkles.
Undefined jawline and sagging cheeks
What it looks like: The jawline is not sharp and the lower cheeks drop toward the corners of the mouth, most visible from the side.
Cause: The fibrous tissue supporting the face and the cheek fat shift downward, together with thinning skin.
Severity/urgency: Not urgent. This group is usually considered for deep-focus ultrasound or deep lifting procedures, while radiofrequency mainly targets skin tightness.
When to see a doctor: When the jawline changes noticeably after weight loss, or when you see asymmetry that was never there before.
Nasolabial folds and marionette lines
What it looks like: Folds running from beside the nose to the corners of the mouth, and from the corners of the mouth down to the chin.
Cause: There can be several contributing parts: sagging cheeks pressing on the fold, lost volume under the cheek, and repeated use of the smile muscles.
Severity/urgency: Not urgent. If the fold is mainly from lost volume, thermal energy gives limited results, so the doctor needs to separate this part first.
When to see a doctor: When you have had a tightening procedure and the folds did not change, or you have had filler and want to add a device treatment.
Under the chin and jowls
What it looks like: Loose skin under the chin, with a double chin when you look down.
Cause: It may be loose skin, fat under the chin, or neck muscles, and genetics play a part. It can occur even when weight is not high.
Severity/urgency: Not urgent. If the cause is mainly loose skin, ultrasound or radiofrequency may be considered. If there is a lot of fat, these procedures may not be the answer.
When to see a doctor: If you can feel a lump under the chin or on the neck, a lump that grows quickly, or pain, have the cause checked first. A lump is not sagging.
Neck and neck lines
What it looks like: Thin, wrinkled neck skin with horizontal lines, or skin that hangs in a sheet when you look down.
Cause: Accumulated sun exposure, skin that is thinner than on the face, and use of the neck muscles.
Severity/urgency: Not urgent. Neck skin is thinner than facial skin, so the energy must be set differently, and marks are more likely if the energy is not suitable.
When to see a doctor: Before any procedure on the neck, and when the neck skin is unusually dark or thickened, which must be told apart from other conditions.
Drooping eyelids and a lot of excess skin
What it looks like: The upper eyelid covers the lash line, or there are sheets of excess skin on the cheeks and neck.
Cause: Skin and muscle change with age, while a drooping eyelid may be caused by weakness of the muscle that lifts the eyelid (blepharoptosis).
Severity/urgency: Not urgent if it develops slowly. Energy-based procedures are usually not enough, and surgery with a plastic surgeon fits the problem better.
When to see a doctor: When the eyelid blocks your vision, and urgently if the eyelid droops suddenly together with double vision or a headache.
Sudden facial drooping or sagging on one side
What it looks like: One corner of the mouth droops, the smile is uneven, or the eye cannot close fully, developing within hours to a few days.
Cause: It may be a stroke, or facial muscle weakness from the facial nerve (Bell’s palsy), not age-related sagging.
Severity/urgency: Emergency, especially if there is also weakness in an arm or leg or slurred speech.
When to see a doctor: Go to the emergency room immediately or call 1669. Do not wait for a clinic appointment.
Deep-focus ultrasound
This group is commonly called HIFU. Ultrasound energy is focused into heat points at set depths, usually around 1.5, 3.0 and 4.5 millimetres, and the deepest setting reaches the fibrous layer that supports the face (SMAS). The tissue responds by contracting and building new collagen over time.
Suitable for: Mild to moderate sagging of the jawline, cheeks and under the chin.
Number of sessions: Usually one session, then reassessment after about 12 months or more.
When results appear: Gradual change at about 2–3 months, which may continue up to 6 months.
During treatment: You may feel pain along the bone. The doctor adjusts the energy and treatment points to the thickness of the skin.
Limitations: It does not replace surgery in marked sagging, and caution is needed in people with hollow faces because of little fat.
Mid-depth ultrasound
Ultrasound energy is delivered to the middle dermis, at about 1.5 millimetres, to stimulate collagen in the skin layer, without intentionally reaching the fibrous layer.
Suitable for: Early sagging, wrinkles, facial skin, the neck and under the chin.
Number of sessions: Usually starting with 1 session, then the doctor reassesses according to the skin.
When results appear: Usually starting to show at 2–3 months and becoming clearer by about 6 months.
Limitations: It works more superficially than deep-focus ultrasound, so it targets skin quality more than lifting the face structure.
Radiofrequency (RF)
Radiofrequency delivers heat spread through the dermis, causing existing collagen to contract and stimulating new production. This differs from ultrasound, which concentrates energy into points.
Suitable for: Loss of skin elasticity, jawline, cheeks, under the chin and neck, at mild to moderate levels.
Number of sessions: Depends on the device and handpiece. It may be a single session or several, and the doctor will give the plan after assessment.
When results appear: The skin feels tight for a short time from swelling at first, while the collagen-based results take about 2–6 months.
Limitations: Not to be used, or the plan must be adjusted, in people with a pacemaker or implanted metal in the area to be treated.
Deep lifting procedures
This is the same group of procedures that deliver energy to deep layers, placing the energy in lines over the target area. It is usually considered for nasolabial folds and marionette lines caused by sagging.
Suitable for: People whose cheeks sag and press on the folds, where the doctor has assessed that the cause is not mainly lost volume.
Number of sessions: Set by the doctor according to skin condition and the interval needed.
Limitations: Folds caused by lost volume or by the smile muscles may change little.
RF microneedling
Fine needles at a depth of about 0.5–3.5 millimetres deliver radiofrequency directly into the dermis. It helps skin quality and is not the main option for lifting the face structure.
Suitable for: Pores, uneven skin and some types of scars.
Number of sessions: Usually about 3–4 sessions, about 4 weeks apart.
Good to know: If your goal is the jawline, discuss whether this method matches the goal. Read more at RF microneedling for skin tightening and pores.
Who is not suitable or should postpone
Pregnant or breastfeeding: Safety data is limited, so postpone.
Implanted devices in the body: A pacemaker or metal in the treatment area must always be declared beforehand.
Rash, inflammation, wounds or infection on the face: For example an active cold sore, which must be treated first.
History of keloids: The risk is higher, especially with needle-based methods. Read Keloids and raised scars.
Taking isotretinoin: Tell the doctor. The waiting period depends on the type of procedure, usually about 1–6 months.
Taking blood thinners: Do not stop the medication yourself. Consult the prescribing doctor.
Previous filler, thread lift or implanted material: Tell us the type and when it was done, so we can leave an interval or avoid those areas.
Flare of an immune disease, or a condition with slow wound healing: For example uncontrolled diabetes.
Expecting results equal to surgery: This should be discussed and agreed before deciding.
Side effects and risks
Common and usually resolve on their own
Redness, swelling and warmth for about 1–3 days
Tenderness when pressing or chewing for about 2–4 weeks
Small bruises, especially with needle-based methods
Uncommon but important to know
Burns, blisters or line marks on the skin: From unsuitable energy or contact.
Temporary numbness or weakness: From affecting a nerve, causing an uneven smile. It usually recovers within several weeks to about 3 months but needs follow-up.
Patchy fat loss: If energy is delivered to the wrong layer or the wrong place.
Post-inflammatory dark marks: More common in darker skin, and if sun protection is not used.
Cold sore flare: If you have frequent cold sores, the doctor may give an antiviral in advance, such as valacyclovir 500 milligrams twice a day for about 5–7 days, at the doctor’s decision.
Scarring: Uncommon. It occurs with needle-based methods or when a burn occurs.
Return to the doctor immediately if you have: Blisters, wounds, pus, pain that increases after 48 hours, a drooping face, or numbness that does not improve.
Realistic expectations
You will not see the full result on the day: Part of the tight feeling on the first day comes from swelling. The real result takes about 2–6 months.
Results are not permanent: Skin keeps changing with age. How long the result lasts depends on age, skin, sun protection and weight.
Results differ from person to person: Some people see a clear change and some see little, and several sessions or a combination of methods may be needed.
Not equal to surgery: Surgery is another option that should be discussed in marked sagging.
Measure results with photos: Photos from the same angle and lighting before treatment and at 3–6 months are better than looking in the mirror every day.
Preparation and aftercare
Before treatment
Tell us about your medical conditions, medications, supplements, and everything previously injected or done on your face.
Stop retinoid creams and exfoliating acids for about 3–7 days if the doctor advises.
Avoid strong sun for about 1–2 weeks before treatment.
After treatment
Wash your face gently, apply a moisturiser, and use sunscreen every day.
Avoid scrubs, retinoids and exfoliating acids for about 3–7 days, or as the doctor instructs.
If a needle-based method was used, avoid make-up for about 24 hours.
Read more at Skin care after laser treatment.
Topical medication and sunscreen that help maintain results
Procedures do not stop the skin from changing, so daily care is part of the plan, and choosing medication is the doctor’s role.
Sunscreen SPF 50 or higher, PA++++: Apply to the face and neck, about 2 finger-lengths, every morning, and reapply every 2 hours when outdoors. How to choose is in Sunscreen: how to choose the right one.
Tretinoin 0.025–0.05%: Apply a thin layer at night. It usually takes 12–24 weeks to see changes in wrinkles and sun-damaged skin. Do not use it when pregnant or planning pregnancy, and it may cause redness and peeling at first.
Vitamin C (L-ascorbic acid) 10–20%: Apply in the morning to complement sunscreen. If it stings, reduce the frequency.
Judge whether it works from photos and how the skin feels at 3–6 months, not in the first week. You can also read about Collagen and skin.

Frequently asked questions about the face lifting clinic in Samut Prakan–Bangna
Where is the dermatologist-led face lifting clinic in Bangna, Samut Prakan?
Siam Dermatology, a dermatology specialty clinic, is at 536/1 Moo 3, Thepharak Road, Thepharak Subdistrict, Mueang Samut Prakan District, Samut Prakan 10270. It is about 9.5 kilometres from Central Bangna and about 750 metres from Thipphawan Station on the MRT Yellow Line. Doctors assess and perform the treatments themselves, for example Dr. Patara Voravutinon, a dermatologist, medical licence no. 54323. Please call +66 61 448 7000 to confirm the day before you travel.
How long does face lifting last?
For most deep-focus ultrasound, mid-depth ultrasound and radiofrequency treatments, results last about 1 year, give or take, depending on age, skin thickness, sun protection and body weight. Results are not permanent because the skin keeps changing with age. Doctors usually reassess after about 12 months or more, and you do not need treatment every year if you are still satisfied. Treating too often without reassessment can increase risk.
How many sessions does face lifting need, and how many months until results show?
It depends on the method and the skin. Deep-focus and mid-depth ultrasound usually start with 1 session. Radiofrequency may be a single session or several depending on the device. RF microneedling is usually about 3–4 sessions, 4 weeks apart. Results from new collagen appear at about 2–3 months and may continue up to 6 months. Keep photos from the same angle to compare, because change is gradual.
How do ultrasound and radiofrequency differ for face lifting?
Deep-focus ultrasound concentrates energy into points and can reach the fibrous layer that supports the face, so it is usually considered when the jawline or cheeks sag. Radiofrequency delivers heat spread through the dermis and focuses on tightness and skin quality. Mid-depth ultrasound works at about 1.5 millimetres and focuses on skin and wrinkles. The choice depends on the sagging layer, skin thickness and contraindications such as a pacemaker. A doctor should examine you before you decide.
At what age should you start face lifting?
There is no fixed age. Sagging usually starts to show in the 30s–40s, but what decides is the real condition, not a number. If the jawline has not changed, daily sunscreen and a retinoid recommended by the doctor may be enough. If sagging is already clear, you can be assessed. If there is a lot of excess skin or you are older, a device alone may give little result, so other options should be discussed.
If the face sags a lot, is non-surgical lifting enough?
Usually not if there are sheets of excess skin or tissue has dropped a lot. Energy-based procedures can tighten only to a limited degree, and repeating them many times does not equal surgery. In this case you should consult a plastic surgeon about a facelift, which involves incisions and a longer recovery but fits the problem better. A dermatologist can tell you at the first visit whether you should have a device treatment, have surgery, or not need anything yet.
