Idea of Skin Icon
The icon is a simplified depiction of a hair follicle embedded in skin, in profile. The hair is represented by a tear shaped figure whose point extends high up above the skin. The skin is a rectangular base with a concave opening where the hair follicle sits. The icon represents the human skin.
This page shows the different variations of the Skin from an Icons8 icon pack. Feel free to resize and recolor the icon, and then download the icon in PNG format for free.
