The thinnest layer of skin is the epidermis, which is the outermost layer of our body. It acts as a barrier against foreign substances, preventing bacteria and viruses from entering deeper layers of skin.
The epidermis varies in thickness throughout the body, being thickest on the palms of the hands and soles of the feet, and thinnest on the eyelids. The eyelid skin is unique because it has no subcutaneous fat. The thickness of the epidermis also varies depending on age, with the skin getting thinner as we age.
