What sagging skin under the eyes is
The lower eyelid skin is around 0.5 mm thick, has almost no fat beneath it and is moved thousands of times a day by blinking and expression. When the collagen and elastin fibres in its dermis thin and fragment, the skin becomes crepey, folds into fine accordion creases on smiling and, in time, hangs in a loose fold beneath the lash line. The medical terms are lower-lid skin laxity or dermatochalasis of the lower lid, and the sagging skin under eyes pillar covers it as a whole. It is a skin problem, distinct from the fat and fluid problems that cause eye bags, and the treatments that work for it are compared on the sagging skin under eyes treatment page.
Collagen and elastin loss under the eyes
From the mid-twenties skin produces about one per cent less collagen each year, and the under-eye skin, being thinnest, shows it first. Elastin fibres, which give the skin its snap, do not regenerate well once damaged. The result is skin that stretches a little more with every blink and recovers a little less. Oestrogen decline around the menopause speeds the loss noticeably in women, so under-eye crepiness commonly appears in the late thirties and is almost universal by the fifties.
Sun damage and crepey under-eye skin
Ultraviolet light breaks down collagen and elastin directly and activates the enzymes that digest them. Most people apply sunscreen to the cheeks and stop below the eye, and few wear sunglasses consistently in Singapore’s year-round UV index of 10 or higher. Photo-aged under-eye skin is thin, finely wrinkled, slightly yellow and often mottled with pigment, and is the main reason crepiness appears earlier in outdoor workers and keen sportspeople.
Eye rubbing, allergy, eczema and under-eye skin laxity
Chronic rubbing stretches the lower-lid skin mechanically and inflames it, and inflammation itself degrades collagen. The usual drivers are allergic rhinitis and allergic conjunctivitis from house-dust-mite allergy, atopic dermatitis of the eyelids, dry eye and contact-lens irritation. Patients who have rubbed their eyes since childhood often have lax, slightly thickened and pigmented lower lids by their thirties. Rubbing also contributes to dark eye circles through post-inflammatory pigment.
Weight loss and sagging under-eye skin
Rapid or large weight loss, including after bariatric surgery or GLP-1 medication, removes the small fat pads of the cheek and lower lid that were supporting the skin. The skin, already stretched, is left with nothing beneath it and drapes into folds. The same mechanism explains why heavy drinkers and smokers, whose facial fat is depleted, show crepiness early.
Sagging skin after eye bag surgery
Lower blepharoplasty, especially the transconjunctival approach done through the inside of the lid, removes or repositions the fat that was pushing the skin outwards. If the skin was already lax, removing the bag can leave it visibly loose, a result patients describe as “the bag is gone but now it is wrinkly”. Surgeons anticipate this by adding a pinch blepharoplasty or laser resurfacing at the same operation, and where they did not, a secondary skin tightening treatment is often needed 6-12 months later.
Other causes of lax lower-lid skin
- Smoking reduces blood flow to the skin and accelerates elastin breakdown.
- Genetics. Fair, thin-skinned families crepe earlier than thick, oily-skinned ones.
- Chronic swelling from salt, alcohol, sleeping face-down, sinus disease or thyroid disease stretches the skin repeatedly.
- Previous filler placed too superficially or in large volumes can stretch the lid skin.
- Medical conditions such as thyroid eye disease and kidney disease cause recurring lid swelling.
Under eye wrinkles, eye bags, festoons or sagging skin, how to tell the difference
| Finding | Sagging skin | Eye bag | Festoon | Fine lines |
|---|---|---|---|---|
| What you see | Crepey, loose skin that folds on smiling | A bulge directly under the lashes | A soft swollen pouch lower down, on the cheekbone | Thin creases in otherwise firm skin |
| Worse in the morning | No | Fluid bags yes, fat bags no | Yes, markedly | No |
| Changes when you look up | No | Fat bag gets bigger | No | No |
| Snap test | Slow return | Normal return | Slow return and puffy | Normal return |
| Cause | Collagen and elastin loss | Fat herniation or fluid | Chronic swelling of the orbicularis skin and muscle on the cheek | Early sun and expression |
| Treatment group | Skin tightening, resurfacing, pinch blepharoplasty | Fat reduction, see eye bag causes | Surgery or specialised treatment | Retinoids, boosters, light resurfacing |
Many patients have both a bag and lax skin, and the bag often needs to be dealt with first.
Snap test, how to check for lax under-eye skin
- Look straight ahead in a mirror in good light.
- With a clean fingertip, pull the skin of the lower lid gently downwards towards the cheek by a few millimetres and release.
-
Count how long the skin takes to return to its resting position against the eye.
-
Within one second. Normal tone, and the concern is more likely fine lines or a bag.
- One to three seconds, or it drifts back. Mild to moderate laxity, which energy-based tightening and resurfacing can help.
- Stays down or needs a blink to reset. Marked laxity, which usually needs a pinch blepharoplasty. The lid margin itself should be checked for looseness, which can cause watering and a turned-out lid.
A second check is the smile test. A broad smile produces accordion creases below the lashes, and creases that persist for a moment after the smile stops confirm lax skin rather than simple expression lines.
When sagging under-eye skin is medical
- A lower lid that sags away from the eye, waters constantly or shows the red inner surface (ectropion) needs an ophthalmologist, because this is a lid-margin problem, not a skin problem.
- Lid skin that is red, scaly or itchy is dermatitis and must be treated before any tightening procedure.
- New swelling of the lids that is worse in the morning, with puffiness elsewhere, may reflect thyroid, kidney or heart problems and needs a GP.
- Sagging that appeared within weeks of eye surgery should be reviewed by the surgeon.
What makes sagging skin under the eyes worse
- Sun without sunscreen or sunglasses.
- Rubbing, from allergy, eczema, dry eye or removing eye make-up roughly.
- Smoking and heavy drinking.
- Rapid weight loss.
- Sleeping face-down or on one side, which stretches the dependent lid overnight.
- Salt, late nights and dehydration, which cause repeated puffiness.
- Heavy or superficial under-eye filler.
Which sagging under-eye skin treatment suits which degree
| Degree on the snap test | Treatments that can work | Treatments that usually will not |
|---|---|---|
| Fine lines, normal snap | Retinoid creams, skin boosters (Rejuran, Juvelook, HA), light fractional laser | Surgery |
| Mild laxity (1-2 seconds) | XERF, Thermage Eyes, Secret RF microneedling, fractional CO2 or erbium laser | Creams alone |
| Moderate laxity (2-3 seconds) | Fractional CO2 laser, combined RF and laser, or pinch blepharoplasty | Boosters alone |
| Marked laxity (stays down) | Pinch blepharoplasty, lower blepharoplasty with skin removal | Any energy device alone |

Frequently asked questions
Why is the skin under my eyes suddenly crepey?
Crepiness usually builds over years but becomes visible suddenly after weight loss, a period of allergy and rubbing, a sunny holiday or a change in lighting or make-up. It can also appear after eye bag surgery has removed the fat that was supporting the skin.
Can sagging skin under the eyes go back to normal?
Mild laxity can be improved by rebuilding collagen with radiofrequency, laser or boosters, but lost elastin does not regenerate and the skin never returns fully to its youthful tone. Marked laxity needs a small amount of skin removed.
Are sagging under-eye skin and eye bags the same thing?
No. An eye bag is a bulge of fat or fluid, whereas sagging skin is loose skin with nothing bulging beneath it. Many people have both, and the bag is usually treated first.
Does eye cream help sagging skin under the eyes?
A retinoid cream used nightly for 6-12 months thickens the dermis slightly and improves fine lines and early crepiness. No cream tightens a skin fold.
What is a festoon and is it the same as sagging under-eye skin?
A festoon is a hammock of chronically swollen skin and muscle lower down on the cheekbone, worse in the morning. It is more difficult to treat than lax lid skin and usually needs a surgeon.
