Dark circles or eye bags? Different problem, different fix.
These two terms are used interchangeably online — but in clinic they're completely different findings that respond to completely different treatments. Filling the wrong one is the most common cause of an "overdone" under-eye result.
One concern. Several possible reasons.
The treatment depends on which one is yours.
Possible causes
Pigment, visible vessels, hollowing, fluid retention and prominent fat pads can overlap; they are not interchangeable.
How we assess it
We assess colour, skin thickness, contour and swelling history. A mirror test cannot reliably diagnose the cause.
Possible options
Skin care or medical investigation, selected treatment for genuine hollowing, or surgical assessment for significant bags. Filler is not an automatic answer.
Dark Circles
Pigment, vascular shadowing, or a tear trough hollow casting a shadow. The skin looks dark but the under-eye is anatomically flat or sunken.
Usually treated with
- · Tear trough filler (when hollowing)
- · Polynucleotides (skin thickness)
- · Pigment-regulating skincare
Eye Bags
Forward herniation of the orbital fat pads or fluid retention. There is a bulge — pinch the area and it stands out.
Usually treated with
- · Lower blepharoplasty (gold standard)
- · Polynucleotides (skin support)
- · Not filler in the bag itself

Common questions
Are dark circles the same as eye bags?+
No. Dark circles are a colour problem (pigment, vascular shadowing, or hollow casting a shadow). Eye bags are a structural problem (fat herniation or fluid retention creating a bulge). They look similar but need different treatments.
Will tear trough filler fix eye bags?+
Only if the 'bag' is actually a hollow casting a shadow. True fat-pad herniation under the eye should not be filled — it usually needs surgical lower blepharoplasty or, in selected cases, polynucleotides for skin quality.
What about pigmented dark circles?+
These respond best to a layered protocol: prescription pigment-regulating skincare (hydroquinone, retinoid, vitamin C), occasionally chemical peels, and polynucleotides to thicken the under-eye skin so vascular shadowing is less visible.
How do I know which I have?+
A mirror or pressure test cannot reliably distinguish pigment, hollowing, swelling and fat-pad prominence. Clinical assessment considers colour, contour, skin quality and your history before recommending any treatment.
