Light and electron microscopic findings with permanent eyeliner
Ophthalmology
|October 1, 1986
Summary
Permanent eyeliner pigment (ferrous oxide) disperses in eyelid tissue, with initial epidermal and dermal presence. Over time, pigment clumps in the dermis, primarily within macrophages, with minimal inflammation observed.
Area of Science:
- Ophthalmology
- Dermatology
- Histopathology
Background:
- Permanent eyeliner involves tattooing the eyelid with pigments, often ferrous oxide.
- Understanding the long-term tissue response to cosmetic tattoos is crucial for patient safety.
Observation:
- Pathologic examination of eyelid specimens after permanent eyeliner application.
- One specimen was analyzed four days post-tattooing, and another 12 months later.
Findings:
- Four days post-tattooing: pigment granules observed in epidermis and dermis with no significant inflammation.
- Twelve months post-tattooing: pigment aggregated in dermis, phagocytosed by macrophages, with minimal mast cells and fibroblasts involvement.
- Electron microscopy confirmed pigment phagocytosis by macrophages and minimal presence in mast cells and fibroblasts.
Implications:
- The study elucidates the dynamic fate of ferrous oxide pigments in eyelid tissue over time.
- Findings suggest a generally non-inflammatory tissue response to permanent eyeliner, with pigment sequestration by cellular mechanisms.
