Tired eyes: telling hollows, shadows and thin skin apart
Four different problems all look like "tired eyes" in the mirror. Treating the wrong one is the most common way people waste money in aesthetics.
More money is wasted on the under-eye area than anywhere else in aesthetics, and almost always for the same reason: the treatment was chosen for the appearance rather than the cause. Four quite different things produce the same complaint.
The four causes
1. Structural hollowing
A genuine loss of volume where the lower eyelid meets the cheek. It creates a groove that casts a shadow, and the shadow is what you see. Test: in flat, even light from the front, does the darkness reduce noticeably? If yes, you are looking at a shadow rather than pigment.
This is the one that responds to volume replacement. It does not respond to skin treatments, no matter how good.
2. Thin, crepey skin
The skin itself has thinned, so the bluish vasculature beneath shows through and fine crinkling appears when you smile. Test: gently stretch the skin sideways. If the darkness lessens and the texture smooths, thin skin is the issue.
This is polynucleotide territory — the treatment designed to thicken and improve compromised skin.
3. True pigmentation
Actual melanin deposition, common in deeper skin tones and often hereditary. Test: it does not change with lighting or stretching. It looks brown rather than blue or purple.
This needs a pigment-directed approach and considerable patience. Aggressive resurfacing around the eye can make it worse, so a cautious, well-planned course matters more here than anywhere.
4. Puffiness and fluid
Worse in the morning, better by afternoon, worse after salt, alcohol or a bad night. Test: does it fluctuate day to day? Then it is fluid, not structure.
This is largely not an injectable problem. Sleep position, salt, alcohol, allergies and hydration account for most of it. A clinic that offers to inject fluctuating puffiness is not paying attention.
The mirror test, in order
- Stand at a window in daylight, no makeup.
- Look straight ahead. Note the darkness.
- Tilt your chin up towards the light. If it largely disappears, it is shadow from a hollow.
- Gently stretch the skin outward. If it improves, it is thin skin.
- If it stays the same in every light and stretch, it is pigment.
- Check again tomorrow morning and tomorrow evening. If it moves, it is fluid.
What we would suggest for each
| Cause | Approach | Realistic outcome |
|---|---|---|
| Thin, crepey skin | Polynucleotide eye course — £400 for three | Genuine improvement in texture and thickness over three months |
| Fluid and puffiness | Lifestyle first, no injectable | Often the biggest change of all, for nothing |
| Pigmentation | Cautious pigment-directed plan and rigorous SPF | Slow, partial, but real over months |
| Structural hollowing | Assessment for volume — a consultation decision | The only cause where a skin treatment alone will disappoint |
What actually helps, for free
- Sleep slightly elevated. An extra pillow moves more fluid than most treatments.
- Salt and alcohol the night before matter more than you think.
- Treat allergies properly. Chronic rubbing thickens and darkens the skin, and the rubbing is often unconscious.
- Wear sunglasses. Squinting is repetitive movement, and UV drives pigmentation in the thinnest skin you have.
- SPF up to the lash line. Most people stop at the cheekbone.
These are unglamorous and genuinely effective. Anyone who tells you otherwise is selling something.
A note on expectations
The under-eye area rewards restraint more than any other part of the face. It is small, thin, mobile and highly visible, and it is where overtreatment shows first. A partial improvement here is usually a better outcome than a complete one attempted aggressively.
Common questions
What causes dark circles under the eyes?
Four different things: structural hollowing casting a shadow, thin skin showing the vessels beneath, true melanin pigmentation, and fluid retention. Each needs a different approach, and most people have two of the four.
What is the best treatment for under-eye hollows?
It depends on the cause. A genuine structural hollow needs volume assessment; thin crepey skin responds to a polynucleotide course; pigmentation needs a slow pigment-directed plan; puffiness is mostly lifestyle and not an injectable problem.
Do polynucleotides help dark circles?
They help when the cause is thin, crepey skin allowing the vessels beneath to show through. They do not fill a structural hollow and they do not remove melanin pigmentation.
How can I tell if my dark circles are shadow or pigment?
Tilt your chin up towards daylight. If the darkness largely disappears, it is shadow from a hollow. If it stays the same in every light, it is pigment.
