Most common reason is “Fatigue”. On times it could be some natural part of aging but that is just shadow of puffing and not true darkness. Even some people like that black circle and Raccon Eyes make up is there outside! Some of the most common causes of that circle are:
- Fatigue
- Aging leads to thining of skin so underlying vessles show off purple
- Heredity
- African and Asian Ethnicity (Irregularity of Pigmentation)
- Eye rubbing and scratching
- Solar pigmentation that caused by sun exposure (Eye cream with Anti-solar properties can protect against that)
- Sinusitis
- Iron deficeincy
- Allergies and Atopics like:
- Atopic dermatitis (eczema)
- Contact dermatitis
- Hay fever (allergic rhinitis)
Causes seen here are common with this symptom. Contact with Dr Joobin or other health care professional for an individualized diagnosis.
Trauma can also cause Raccon Eye sign which has different clinical picture and is sign of skall base fracture.
