Why do dark circles under the eyes occur?

The appearance of dark circles under the eyes is usually due to a combination of several factors. The main one is usually a hereditary or constitutional predisposition to develop them more easily than other people, due to a thinner skin that allows you to appreciate the dark color of the blood vessels that run deeper. Other factors that facilitate their appearance are stress or fatigue, which favor dehydration of the tissues surrounding the eye and dilation of the blood vessels. This is what gives dark circles under the eyes an even more pronounced appearance. 

This treatment is suitable for any type of dark circles, being the most beneficial those that appear in patients who do not have bags in which the dark circles are mainly due to sagging at the periorbital level, and darkness due to the thinness of the skin in that area.
