Human Skin Flakes

Human Skin Flakes

Human skin flakes tend to be equant in planar view, as opposed to the more assymetric pattern seen in most other animal dander.

Characteristic Features:

Human dander varies from isotropic to particles with stress birefringence. The stress birefringence of human skin flakes tends to be low. The refractive index of human skin flakes tends to be around 1.550 but will vary with stress and oil content.
