Under eye circles are known as Periorbital Dark Circles. They show as discolouration, whereby dark blue, purple or green toned patches appear under and around the eyes
There are two main ways that dark under eye circles show, both with different causes:
- When blood vessels in the under eye area show through the skin of the eyes, presenting as a blue or green undertone.
- From hyperpigmentation, where excess melanin causes darkening of the skin, known as Periorbital Hyperpigmentation.
Due to many contributing factors, it is not always easy to treat dark circles with one option.
There are definitely a few things you can do to help, like applying targeted eye creams
