Three different problems look the same in a mirror. Each one needs a different tool.

Dark circles have three common causes: thin, translucent skin that shows the vessels underneath, pigment from sun exposure, and hollowness that casts a shadow. Dr. Ourian treats each cause differently. Coolaser for pigment, light-based treatment for visible vessels, and injection for hollows. Creams and concealers cover the problem. They do not change it.

Frequently asked questions
What causes dark circles under the eyes?
Three things, often in combination: thin translucent skin that shows the vessels underneath, pigment from sun exposure, and hollowness that casts a shadow. Genetics can make each one worse.
Do eye creams get rid of dark circles?
No. Creams and concealers can make dark circles less visible for a while, but they do not change the thin skin, pigment, or hollowness causing them.
Is under-eye filler dangerous?
It is a difficult area to treat. Dr. Ourian says the risk is managed by understanding the anatomy and working gradually, rather than filling one spot.
How many sessions does under-eye treatment take?
Usually one or two sessions, in Dr. Ourian's words, depending on the cause.
Can under-eye bags be treated without surgery?
Often, yes. Coolaser can tighten the skin around the eye and reduce some of the fat beneath it for patients not ready for eyelid surgery.
