As you can feel, the skin around the eyes is much different than the rest of the face. “Eyelid skin is amongst the thinnest skin of anywhere on the body, and therefore it should come as no surprise that it’s extra-sensitive and delicate,” board-certified dermatologist Rebecca Marcus, M.D. tells mbg.
