Blepharoplasty: complete guide to eyelid surgery (2026)

1 Introduction: the surgery that restores vitality without changing the gaze

The eyes are the first thing we perceive in someone. They communicate energy, fatigue, joy or sadness — sometimes independently of what the person actually feels. When eyelids become heavier over time or bags appear under the eyes, the gaze can express a permanent fatigue or sadness that no longer corresponds to the person's inner state. This is precisely where blepharoplasty intervenes — not to transform the gaze, but to restore the vitality it once had.

A fundamental truth must be stated from the outset: a well-performed blepharoplasty does not change the gaze, it reveals it. The apparent paradox of this surgery is that it brings a visible change while leaving an impression of absolute naturalness — close friends notice that you look "more rested", without being able to precisely identify what has changed. This is precisely the sign of a successful procedure, and it is the objective that must guide every technical decision.

Several types of blepharoplasty exist, corresponding to very different anatomical situations. Upper blepharoplasty treats excess skin of the upper eyelid. Lower blepharoplasty addresses fatty bags and excess skin under the eyes. Ptosis correction treats eyelid drooping due to levator muscle involvement — a technically different procedure from simple excess skin removal. Canthopexy supports the outer corner of the eye. Confusing these indications leads to operating on the wrong anatomical plane — with insufficient results or serious complications.

This guide covers the entire spectrum, from non-surgical alternatives for mild cases to eyelid surgery in all its complexity, including male-specific considerations. Rigorous information is the first act of safety — and safety begins before even entering a practice.

2 Eyelid anatomy and ageing of the gaze

The upper eyelid is one of the most complex anatomical structures in the human body given its reduced size. It is composed of several distinct layers: the skin (the thinnest in the entire human body — barely a few tenths of a millimetre), the orbicularis oculi muscle, the orbital septum, the pre-aponeurotic fat, the levator muscle aponeurosis, and the conjunctiva. Each of these layers plays a precise role in the mechanics and appearance of the eyelid. A surgical gesture that does not rigorously identify these planes risks damaging the levator muscle — with serious functional consequences.

The lower eyelid is organised differently. The orbital fat is distributed in three distinct compartments (medial, central, lateral) that the orbital septum naturally contains. Over time, this septum relaxes and allows fat to herniate forward — creating the characteristic bags that give an appearance of permanent fatigue. Simultaneously, the loss of volume of periorbital soft tissues (temporal hollow, infraorbital groove, tear trough) creates a contrast between the protruding bag and the adjacent hollow areas, worsening the appearance of dark circles.

Ageing of the periorbital region is multidimensional: progressive skin excess on the upper eyelid due to gravity and decreased skin elasticity; relaxation of the lower orbital septum with bag formation; brow ptosis which increases the apparent skin excess on the upper eyelid; and progressive resorption of the orbital bone which widens the orbit and deepens hollow dark circles. This complexity explains why meticulous preoperative analysis is indispensable — treating only the skin when brow ptosis is the main cause of apparent skin excess leads to an unsatisfactory result and often an early revision request.

The most important differential diagnosis in upper blepharoplasty is the distinction between simple skin excess and true eyelid ptosis. True ptosis is a drooping of the upper eyelid caused by insufficiency or detachment of the levator muscle aponeurosis — measured by the margin-reflex distance (MRD1), which evaluates the position of the upper eyelid margin relative to the corneal reflex. Operating on skin excess without correcting an associated true ptosis, or conversely performing ptosis correction on a simply heavy eyelid, are errors with important functional and aesthetic consequences. A systematic preoperative ophthalmological assessment is indispensable in both cases.

3 Upper blepharoplasty

Upper blepharoplasty is the aesthetic surgical procedure with the best result-to-facial-impact ratio. For a scar placed in the natural eyelid crease — invisible when the eyes are open — it allows recovery of an open, luminous and rested gaze that patients often describe as "recovering the look of ten years ago". Its exceptional durability (10 to 15 years depending on skin evolution) makes it one of the best investments in all facial aesthetic surgery.

The principle is the controlled excision of an elliptical spindle of excess skin, with or without resection or repositioning of pre-aponeurotic fat depending on the case. Preoperative marking is the most critical step of the entire procedure: it precisely defines the exact amount of skin to remove to achieve an open gaze without compromising eye closure. The fundamental rule is that at least 20 mm of tissue must remain between the lash margin and the brow after resection — below this limit, the risk of lagophthalmos (inability to completely close the eye) becomes significant. Marking is performed in a seated or standing position, never lying down, as gravity modifies tissue position.

The question of fat resection is more nuanced than it appears. Aggressive resection of pre-aponeurotic fat can create a hollow, ageing and unnatural gaze that is more difficult to correct than an initial excess. Current 2026 standards favour fat preservation or repositioning rather than systematic resection — except in cases where the fat volume is genuinely excessive and contributes to the heavy appearance of the eyelid.

Upper blepharoplasty can be performed under simple local anaesthesia in the vast majority of cases — a considerable advantage in terms of comfort, safety and recovery. It can also be performed under light general anaesthesia (neuroleptanalgesia) if combined with other procedures. Operative duration for isolated upper blepharoplasty is generally 45 to 75 minutes. Finally, when visible skin excess is mainly caused by brow ptosis, treating only the eyelids without addressing brow position will lead to a disappointing medium-term result — a global analysis of the upper third of the face is indispensable.

4 Lower blepharoplasty

The transconjunctival approach — the reference for bags without skin excess

Transconjunctival lower blepharoplasty is performed through the inner surface of the eyelid (conjunctiva), without any external skin incision. It is the reference technique for patients presenting lower fatty bags without skin excess — typically young or middle-aged patients whose skin is still toned. It allows controlled repositioning or resection of fat from the three orbital compartments, eliminating bags without creating a visible scar and without exposing to the risk of ectropion (outward turning of the lower eyelid). Recovery is generally faster than with the transcutaneous approach.

An important technical point widely adopted by current standards: repositioning orbital fat towards the infraorbital groove (tear trough) is often preferable to simple resection. By filling the hollow adjacent to the bag rather than only removing the bag, a more natural and rejuvenating result is obtained — the bag disappears and the hollow is attenuated in a single gesture. Pure resection, especially if excessive, can create a hollow and tired gaze, paradoxically more ageing than the initial bag.

The transcutaneous approach — when there is associated skin excess

Transcutaneous lower blepharoplasty is indicated when there is lower skin excess associated with bags — generally after age 50, when the skin has lost sufficient elasticity. A subciliary incision is made 1-2 mm below the free margin of the eyelid, allowing access to deep planes and resection of a measured skin spindle. The precision of this resection is crucial: excessive resection is the main cause of ectropion — an aesthetically and functionally serious complication, difficult to correct, that turns the eyelid downward and exposes the conjunctiva. Canthopexy is frequently performed in addition to prevent this risk in patients with reduced canthal tone.

5 Eyelid ptosis and canthopexy

True eyelid ptosis is a drooping of the upper eyelid caused by insufficiency or detachment of the levator muscle aponeurosis — the mechanism that raises the eyelid when opening the eyes. It is distinguished from simple skin excess by an objective criterion: the margin-reflex distance (MRD1) is less than 3.5 mm. It may be congenital, or progressively acquired with age (aponeurotic ptosis), or occur following a trauma or previous surgery (iatrogenic ptosis).

Ptosis correction is a technically different procedure from classic blepharoplasty. It requires identifying and repairing or reinforcing the levator aponeurosis via an anterior or posterior approach depending on the case. The most common error is performing simple skin excision on true ptosis: the result is insufficient because the eyelid-lifting mechanism is not treated, and recurrence of the heavy appearance is inevitable. A surgeon who does not perform MRD1 measurement in consultation cannot correctly distinguish the two situations.

Lateral canthopexy is a support procedure for the lateral canthal ligament — the structure that anchors the outer corner of the eye to the orbital bone. Its progressive relaxation contributes to the sad and descending appearance of the gaze. Canthopexy is frequently associated with transcutaneous lower blepharoplasty to prevent ectropion, but can also be performed in isolation to slightly lift the outer corner and give the gaze a slightly more "cat eye" appearance — a strongly growing demand, particularly among young women. Canthopexy must be distinguished from canthorraphy (permanent eyelid suture) and canthoplasty (bony repositioning of the canthus) — three different procedures with very distinct indications and results.

6 Specifics of male blepharoplasty

Male blepharoplasty is a rapidly growing field, still insufficiently documented in guides accessible to the general public. Men's demand for eyelid surgery is often motivated not by an aesthetic concern in the strict sense, but by a mismatch between the perceived gaze and the felt energy: a gaze that communicates fatigue or sadness while the person feels fully active professionally and personally. It is a functional as much as an aesthetic feeling.

The anatomical differences between male and female eyelids are decisive for surgical planning. Male skin is thicker and more sebaceous. The male brow is positioned lower, at the level of the orbital rim or just above, with a more horizontal course — in women, the brow is naturally above the orbital rim, with a more rounded curve. The upper eyelid crease is lower in men — around 6 to 8 mm from the lash margin versus 8 to 12 mm in women. These differences impose adapted preoperative marking: too high or too extensive a resection would create a feminine eyelid crease, one of the most visible and difficult errors to correct in revision.

Lower bags are very common in men, sometimes hereditary, and male demand for lower blepharoplasty is high. The transconjunctival technique is often preferred for its absence of external scarring and postoperative discretion. The discretion of the procedure and result is moreover an explicit priority for the majority of male patients: rapid return to professional life, recovery without lasting visible signs, and a result that close friends cannot precisely identify are objectives that condition the choice of technique. Bruising and swelling must be planned in the schedule — typically 10 to 14 days of visible social recovery.

7 Non-surgical alternatives for the eye area

Non-surgical alternatives have a real and documented place for mild cases, or as complementary treatments to surgery. They do not replace surgical blepharoplasty when this is indicated — this clarification must be made clearly, as frequent confusion pushes patients to repeat temporary treatments while avoiding surgery that would durably resolve the problem.

Botulinum toxin in the periorbital region allows slight brow lifting (2 to 4 mm) by relaxing the orbicularis muscle that pulls it downward — a useful effect for patients whose apparent skin excess is mainly due to mild to moderate brow ptosis. Crow's feet injections are the best-documented indication. Durability is 3 to 5 months. Toxin does not treat skin excess, fatty bags or true ptosis.

Hyaluronic acid in the periorbital region allows treatment of hollow dark circles (tear trough, infraorbital sulcus) with significant results in terms of rested and luminous gaze. It is technically the most delicate injection in all aesthetic medicine: the risk of Tyndall effect (bluing from too superficial injection), the risk of irregularities, and above all the risk of retinal vascular occlusion make it a procedure to be reserved for physicians expert in periorbital anatomy. In Switzerland, Swissmedic regulates the injectable products used, and cantonal regulations define the conditions of practice. Durability is 6 to 12 months depending on product and zone.

Platelet-rich plasma (PRP) under the eye improves skin quality and can attenuate coloured dark circles (vascular and pigmentary component) by fibroblast stimulation on the extremely thin skin of the lower eyelid. It treats neither bags nor hollow dark circles. Fractional radiofrequency and fractional CO2 laser periorbital allow skin remodelling for fine lines and mild laxity — with a few days of recovery. Plasma (Plexr) offers non-surgical skin retraction for mild excesses, an alternative to superficial blepharoplasty for patients who refuse surgery. None of these techniques treat bags, true ptosis or advanced skin excesses.

8 Risks, contraindications and recovery

Blepharoplasty has an excellent safety profile in a rigorous medical context — it is one of the best-documented aesthetic procedures in the world. But the eyelid area is one of the most vascularised on the face, and certain complications, although rare, deserve to be presented honestly, as they condition the precautions to take before and after the procedure.

Retrobulbar haematoma is the most serious complication of blepharoplasty, exceptional (approximately 0.04% of procedures) but potentially very serious. It generally occurs within 24 hours of the procedure and manifests as intense pain, exophthalmos (protrusion of the eyeball) and rapid decrease in visual acuity. It is an absolute surgical emergency — immediate decompression is necessary to preserve vision. Every operated patient must be informed of these warning signs and have access to the surgeon's emergency contact in the first days.

Ectropion (outward turning of the lower eyelid) is the most frequent complication of transcutaneous lower blepharoplasty, caused by excessive skin resection or deficient canthopexy in patients with reduced canthal tone. Lagophthalmos (inability to completely close the eye) can occur after overcorrection of upper blepharoplasty — it exposes to potentially serious exposure keratitis if not correctly managed. Aggravated dry eye is a real risk for patients with pre-existing dryness — this is precisely why the preoperative Schirmer test is imperative.

Recovery after blepharoplasty follows a predictable timeline: bruising is maximal at day 3-4 and resolves in 10 to 14 days. Oedema gradually decreases over 3 to 6 weeks — the gaze may appear slightly asymmetrical during this phase, which is normal and transitory. The final result is established at 3 to 6 months for upper blepharoplasty, sometimes up to 6 to 9 months for lower. Strict sun protection of scars for 6 months is indispensable to prevent hyperpigmentation.

Patience is part of the protocol. A result evaluated at day 30 is not the final result — oedema continues to resolve for several months and progressively transforms the appearance of the periorbital region.

9 How to prepare your consultation

The preoperative consultation is the most important step of the entire blepharoplasty journey. This is where the quality of the result is determined — well before the surgeon touches the instruments. A rigorous consultation includes standardised photographic analysis of the eyelids in standing position, MRD1 distance measurement, Schirmer test, evaluation of lateral canthus tone, and a detailed discussion on realistic expectations and technical limits. It should last at least 45 minutes for surgery of this complexity.

The questions to ask during consultation allow evaluation of the practitioner's level of expertise and honesty. Have you performed a Schirmer test and MRD1 measurement to evaluate my possible ptosis? What technique do you choose for my precise anatomy, and why not another? Will you evaluate my brow position before planning skin resection? What is your protocol in case of retrobulbar haematoma in the first 24 hours? Can you show me results at 6 and 12 months — not only at day 30?

Certain signals should raise concern. A practitioner who does not perform prior ophthalmological assessment. A surgeon who proposes blepharoplasty without mentioning brow ptosis in their analysis. A consultation too short without standardised photographs. Promises of spectacular results without discussion of limits. Conversely, a practitioner who says "your skin excess is mainly linked to brow ptosis — operating only on the eyelids will not give you the result you expect" or "your mild dry eye requires particular post-operative monitoring" is a practitioner who places rigour and safety above selling a procedure.

In Switzerland, certified plastic surgeons are members of the SSCP (Swiss Society of Plastic, Reconstructive and Aesthetic Surgery). Ophthalmologists specialised in oculoplastic surgery can also perform blepharoplasties within their area of competence. Verifying certifications and specific experience in eyelid surgery is a legitimate and recommended approach. In Swiss cantons, cantonal health authorities supervise medical practices — an additional level of regulatory protection to be aware of.
