Dark circles: four different problems, four different fixes.

A hollow, thin skin, pigment or a puffy bag each cause “dark circles” and each needs a different treatment. Filler is right for only one of them.

“I want filler for my dark circles” is a request we hear weekly. Sometimes it is exactly right. Often it is not, because dark circles are four different things that look alike in a mirror.

1. The hollow (tear trough)

A groove between the lower lid and the cheek throws a shadow that reads as darkness. Look in a mirror with light from above: if the shadow disappears when you light the face from the front, it is a hollow. A small amount of soft hyaluronic acid filler placed deep with a cannula fills the groove and the shadow is gone. This is the only type where filler is the answer.

2. Thin, transparent skin

The skin under the eye is the thinnest on the body. When it is thin, the purple muscle and blue veins show through. Filler makes this worse. Salmon DNA (polynucleotides) and skin boosters thicken and brighten the skin over a course of three sessions.

3. Pigment

Brown rather than blue, often in darker skin, often inherited, worsened by rubbing, allergies and sun. Treated with careful peels, topical brighteners and strict sunscreen. Injectables help only a little here.

4. Puffiness

A bag that casts a shadow below it. Caused by fat herniating forward or by fluid. Filler under a bag makes the eye look heavier. Mild cases improve with skin boosters and lifestyle changes; a true fat bag is a surgical question, and Dr. Sara, as a plastic surgeon, will tell you so.

Most people have two of these

Which is why the consultation matters more than the product. Dr. Sara looks at you in daylight, stretches the skin, checks the hollow with light, and plans in the right order: skin first when the skin is thin, hollow second.

Quick answers

Does under-eye filler look puffy?

Only when too much is used or when placed in a person who had puffiness to begin with. Correct patient, small volume, deep placement: it looks like rest.

How long does tear-trough filler last?

Nine to fifteen months, often longer because the area hardly moves.

Is under-eye filler safe?

In experienced hands with a cannula and the right product, yes. It is an advanced area and not for a beginner injector.
