Dark circles are the complaint people bring to a clinic most convinced of the cause, usually tiredness, and least often right about it. Sleep affects them, but the circles that persist through a good week have structural causes, and there are three. Which one you have decides the treatment, and the wrong match is expensive.
Shadow from hollowing
The most common cause after the mid-30s. The fat and bone under the eye recede, the area sinks into a trough, and the overhead light casts a shadow into it. The skin itself is not dark; the shape is. Tilt your head back and the shadow disappears. Under-eye filler, placed precisely in the tear trough with a cannula, restores the volume and the shadow lifts. Done well it is one of the most rejuvenating treatments on the face, and done badly it is the most visible, which is why the choice of injector matters more here than anywhere.
Vessels through thin skin
Under-eye skin is the thinnest on the body, and with age and sun it gets thinner. The purple-blue tint of the vessels beneath shows through, especially in fair skin. Stretch the skin gently and the color stays, looking bluish. Filler can help by adding a layer between skin and vessel, but the direct fix is thicker skin. Fractional laser resurfacing and PRP microneedling both thicken and smooth under-eye skin over a few sessions, so less shows through, and both improve the fine lines that make the area look tired.
True pigment
Brown discoloration that stays brown when the skin is stretched is pigment in the skin itself, more common on olive and darker complexions and often hereditary. Filler does nothing for it and resurfacing can make it worse in the wrong hands. A series of gentle chemical peels designed for the under-eye area lightens pigment gradually, supported by prescription brighteners and strict sunscreen. Progress is slow and real.
When the circle is a bag
If what you see is a bulge with a shadow beneath it, the shadow is being cast by fat that has pushed forward, and no injectable fixes a bag. Blepharoplasty removes or repositions the fat and is the honest answer. Our guide to under-eye bags covers that decision.
Most people have more than one of these. The consultation that separates them is the treatment.
How to choose a provider
Ask the provider to do the tilt test and the stretch test with you and name the cause before naming a product. For filler, ask how many tear troughs they inject a month, whether they use a cannula, and to see healed results in daylight. For pigment, ask what peel they use under the eye specifically. And ask what they would do if the cause is a bag; the answer should include a surgeon.
