The three clinical types and how to identify yours
Type 1 — Vascular (bluish-purple): Caused by sluggish blood circulation and deoxygenated haemoglobin visible through thin skin. Test: press gently — colour blanches temporarily. More common in fair-skinned individuals but prevalent in Indian women with thin periorbital skin. Worsened by sleep deprivation, dehydration, excessive screen time, and allergic rhinitis (the "allergic shiner"). Type 2 — Pigmentary (brownish): Melanin overproduction in the periorbital epidermis. The most common type in Fitzpatrick IV-VI. Constitutional (genetic) in 62% of cases, meaning it has been present since adolescence. Worsened by UV exposure, hormonal fluctuations, and friction from eye rubbing. Test: colour does not change with pressure. Type 3 — Structural (shadow-based): Caused by tear trough volume loss, under-eye fat herniation (bags), or deep-set eye anatomy. Creates shadow that mimics dark circles. Test: tilt head backward under overhead light — if circles disappear, they are structural. Many Indian women have two or three types simultaneously, which explains why single-ingredient eye creams consistently fail.
