Pouches or bags of the upper and lower lids are generally due to herniations of the fat normally localized within the eye socket. The bulge also casts a shadow over the undereye area, causing it to appear darker.
However, other components are responsible for dark undereye circles. These include:
Hyperpigmentation of the lower eyelid skin
Transparent lower eyelid skin, allowing the underlying blood vessels to be visible, which can appear dark purple.
A bony deficiency called tear trough deformity
All these issues require different approaches, which Dr. Indeyeva will discuss with you after evaluating your skin and facial anatomy.
