Facial rejuvenation and refinement

01

What is a deep plane facelift and how does it differ from a conventional facelift?

A deep plane facelift dissects and elevates beneath the superficial musculoaponeurotic system (SMAS), repositioning the facial soft tissue as a single unit rather than tensioning the overlying skin. The result looks more natural, avoids a pulled appearance, and lasts longer because the lift is borne by supporting structures rather than skin.

Clinical detail

Older-generation facelifts dissected mainly in the subcutaneous plane and tensioned the skin. The difficulty is that skin is not a load-bearing structure; tensioning it creates an unnaturally flat appearance, distorts the auricular contour, and relaxes quickly as the skin continues to stretch.

The true driver of midface ageing is not excess skin but descent of the deep fat compartments and the SMAS layer. The deep plane technique addresses that cause directly, so it improves the nasolabial fold and jawline, regions a superficial lift barely affects.

The trade-off: this is a considerably more complex operation with longer operative time, requiring detailed knowledge of facial nerve branch anatomy within the dissection field. Not every facility performs it, and the cost is higher than a conventional lift.

02

How long does a facelift last?

With deep plane technique, the effect typically holds for 10 to 15 years. The correct framing is important: surgery does not stop ageing, it resets the starting point. You continue to age afterwards, but from a consistently younger baseline than if you had not intervened.

Clinical detail

Factors that shorten longevity: smoking, unprotected sun exposure, large weight fluctuations, poor baseline skin quality and genetics. The first two are entirely modifiable.

A facelift addresses tissue laxity and descent but does not improve skin surface quality: pigmentation, telangiectasia, fine static lines or coarse texture. This is why most comprehensive rejuvenation plans combine surgery with resurfacing and regenerative treatments.

Volume loss is a separate axis of ageing. Many facelifts are combined with autologous fat grafting to restore temple, malar and periorbital volume, because lifting without volume restoration produces a taut but hollow appearance.

Maintaining periodic minimally invasive rejuvenation after surgery is what sustains the result longest. Surgery resets the starting point; regular light treatments slow the rate of decline from it.

03

At what age should someone consider a facelift?

There is no fixed age. The indication rests on the degree of soft tissue descent and skin laxity, not on chronological age. Most suitable candidates fall between 45 and 65, but some patients at 40 have a clear indication while others at 60 do not yet need it.

Clinical detail

Signs that surgery is worth considering: loss of jawline definition, jowling at the mandibular border, nasolabial folds that are deep at rest, and cervical skin banding. Once these are established, non-surgical options are usually insufficient.

Intervening too early does not deliver benefit proportionate to risk and cost, because there is little to lift. Intervening too late means the skin has lost much of its elasticity, giving a less durable result and higher wound healing risk.

RASA generally advises a staged pathway: maintenance and volume restoration in the earlier phase, moving to surgery once structural descent is evident. This avoids both premature surgery and the overuse of filler to defer an indication that has already matured.

04

Will eyelid surgery (blepharoplasty) change the character of my eyes?

This is a reasonable concern and depends entirely on surgical principle. When only the necessary amount of skin is excised and the existing lid architecture is respected, the eyes look more open and rested while remaining recognisably yours. Character changes when too much skin is removed or the crease is set too high relative to native anatomy.

Clinical detail

Crease height is the decisive parameter. A high crease creates a larger-appearing eye but can look foreign on an Asian face, and once created it is very difficult to lower. RASA tends towards a conservative crease height, favouring natural over dramatic.

Excessive upper lid skin excision is the hardest complication to correct. It results in lid retraction, incomplete closure and chronic dry eye. The safe principle is to leave enough skin for complete closure: under-resection is preferable to over-resection.

In true ptosis, skin excision alone does not solve the problem and levator surgery is required. Distinguishing genuine ptosis from dermatochalasis is an essential preoperative step.

05

How long does swelling last after eyelid surgery?

Swelling and bruising peak in the first 3 to 5 days and reduce markedly after suture removal at day 5 to 7. By weeks 2 to 3 you can resume normal activity and work. Full settling of the crease and fading of the scar takes around 3 to 6 months.

Clinical detail

The two eyes rarely settle at the same rate; one side may remain swollen a few days longer. This is a normal course, not a sign of asymmetric surgery. Symmetry should only be judged from the third month onwards.

Cold compresses for the first 48 hours and sleeping with the head elevated reduce swelling substantially. After 48 hours, switch to warm compresses to help bruising resolve.

Factors that prolong swelling: rubbing the eyes, prolonged head-down posture, alcohol, early heavy exercise and sun exposure. Avoid these for at least the first two weeks.

06

What is the difference between botulinum toxin and dermal filler?

Botulinum toxin temporarily relaxes muscles beneath the skin and treats dynamic expression lines such as forehead lines, glabellar frown lines and crow’s feet. Filler restores volume where tissue is deficient and treats deep folds, temple hollowing, chin and lip shaping. They address different problems and are often combined.

Clinical detail

A distinction you can make on your own face: lines visible only on expression are dynamic and respond to botulinum toxin. Lines still visible with the face fully relaxed are static and require filler or resurfacing.

Duration differs: botulinum toxin typically lasts 3 to 6 months, hyaluronic acid filler 9 to 18 months depending on product and site.

Neither addresses skin laxity or tissue descent. Using filler to compensate for structural descent produces a heavy, overfilled face, a recognisable and difficult-to-reverse appearance.

07

Does botulinum toxin cause a frozen face?

A frozen appearance results from excessive dose or misplaced injection, not from the drug itself. With appropriate dosing and accurate placement, muscles are softened rather than paralysed: lines reduce noticeably while you retain the ability to frown, smile and express normally.

Clinical detail

The forehead is where problems most often arise. Over-treating frontalis abolishes brow elevation and can cause brow ptosis, leaving the face heavier than before treatment. The principle is that forehead treatment must be balanced against the brow depressor muscles.

Onset is at 3 to 7 days with peak effect around day 14. Neither the result nor any top-up should be assessed before the two-week mark.

The effect is fully reversible. If the result is unsatisfactory, it returns to baseline within a few months. This is an important distinction from irreversible interventions.

08

Does filler dissolve completely, and what are the risks?

Hyaluronic acid filler resorbs over 9 to 18 months and can be actively dissolved with hyaluronidase if required. The most serious complication is vascular occlusion when filler enters a vessel, which can cause skin necrosis or blindness. This risk is very low with correct technique, correct anatomical plane and a properly trained injector.

Clinical detail

The highest-risk areas are around the nose, the glabella and the nasolabial fold, because of anastomoses with the ophthalmic artery. Injection here requires detailed vascular anatomical knowledge.

Only hyaluronic acid fillers of verified provenance should be used. Permanent fillers and unverified injectable substances account for most of the severe, delayed and difficult complications RASA sees, because they cannot be dissolved enzymatically.

Signs requiring emergency management immediately after injection: disproportionate pain, skin blanching followed by dusky discolouration, and reduced or lost vision. If these occur, contact the injecting clinic immediately rather than waiting.

09

Facial fat grafting or filler: which should I choose?

Filler suits localised volume restoration, an immediate result, avoidance of surgery and acceptance of periodic repetition. Autologous fat grafting suits widespread volume restoration, a long-term result using your own tissue, and acceptance of an anaesthetic procedure with several weeks of swelling.

Clinical detail

On long-term cost, fat grafting is usually more economical where multiple areas need volume. A full-face fat grafting session costs roughly the same as several extensive filler treatments, but the surviving fat persists indefinitely.

Fat grafting offers something filler does not: adipose tissue contains mesenchymal stromal cells, and clinically many patients show improvement in skin surface quality at the grafted site, not only added volume.

The drawback is less predictable final volume, since resorption rates vary between individuals, and a second session may be needed. Filler allows more precise volume control and immediate adjustment.

10

Do thread lifts actually work?

Thread lifts do work, but modestly and temporarily, typically lasting 12 to 18 months. Properly understood, they are a method for pre-empting ageing rather than treating it once established. They suit patients with mild descent who are not yet surgical candidates and want subtle jawline improvement without significant downtime.

Clinical detail

The limitation is mechanical: threads anchor into soft tissue rather than fixed structures, so lifting capacity depends on tissue quality. In patients with significant laxity, threads cheese-wire through the tissue and the effect is lost quickly.

A recurring problem in practice is that thread lifts are proposed to patients who genuinely have a surgical indication. The result is repeated expenditure without addressing the underlying issue, plus tissue fibrosis that complicates any later operation.

Possible complications include palpable or visible threads, dimpling at anchor points, asymmetry and prolonged discomfort. Most resolve, though some require thread removal.

11

What is Profhilo and how does it differ from conventional filler?

Profhilo is a high-concentration, non-cross-linked hyaluronic acid formulation designed to diffuse through tissue and improve skin hydration and elasticity rather than create volume. Put simply: filler fills a hollow, Profhilo improves skin quality across an area.

Clinical detail

Because it is not cross-linked, Profhilo does not hold shape and is not used for structural work such as chin projection or malar augmentation. Classifying it as a volumising filler misrepresents its mechanism.

The standard protocol is two sessions four weeks apart, then maintenance every six months. The clearest changes are in skin turgor and smoothness, usually evident from weeks 4 to 6.

Suitable indications: early loss of elasticity, dullness and fine static lines in patients aged 30 to 50. It is not appropriate where the principal issue is structural descent or significant volume loss.

12

Who is a candidate for a brow lift?

A brow lift suits patients with brow descent that makes the eyes look heavy and tired, or those whose brow-to-lid distance is too short for blepharoplasty alone to help. A useful sign: gently lifting the brow with your fingers visibly refreshes the face.

Clinical detail

A common misconception is that upper lid skin excess is always treated by blepharoplasty. In many cases that excess originates from a descended brow. Operating on the lid in that situation shortens the brow-to-lid distance further and makes the face look heavier.

A simple mirror test: place a finger at the tail of the brow and lift about 5mm. If the appearance improves markedly, the problem is at the brow. If little changes, the problem is at the lid.

Options range from a minimally invasive temporal tail lift to endoscopic forehead lifting. The choice depends on the degree of descent, hairline position and forehead height.

13

Chin augmentation: implant or filler?

Filler suits minor refinement, trialling a shape before committing, or avoiding surgery. An implant gives a stable long-term result with greater projection, and suits genuine retrogenia where structural change is needed.

Clinical detail

Using chin filler as a trial is a sound strategy: you see the new profile for around a year before committing to something permanent. The cost of that trial is usually justified.

For significant retrogenia, filler has clear limits. Injecting large volumes to compensate for projection widens the chin laterally rather than advancing it, and filler tends to migrate over time.

Occlusion should also be assessed. Some cases of apparent retrogenia reflect a jaw relationship problem requiring orthodontics or orthognathic surgery. A chin implant then masks the appearance without addressing function.

14

At what age should skin rejuvenation begin?

Collagen declines by roughly 1% per year from age 25. The window of 25 to 35 is therefore a sensible time to begin maintenance: rigorous sun protection, active-ingredient skincare, and light regenerative interventions. Preserving existing collagen is considerably easier than restoring it once lost.

Clinical detail

Distinguish early prejuvenation from over-treatment in young patients. Prejuvenation means maintenance and prevention, not injecting filler or toxin without indication. At 25 to 30, most of the value comes from sun protection and skincare rather than procedures.

The single highest-impact and least expensive factor remains sun protection. Ultraviolet exposure accounts for most visible skin ageing. No procedure compensates for years of unprotected exposure.

Once mild laxity appears, non-surgical options such as radiofrequency, HIFU or thread lifting can be introduced. These act on tissue firmness and belong to the preventive and maintenance phase, before structural descent becomes established.

RASA works from an individualised pathway based on skin condition and goals rather than fixed packages. The initial assessment establishes where you sit on the ageing trajectory and what is genuinely worth doing at this stage.
