Types of skin
Your skin might be one organ, but it’s not the same all over your body; different zones vary in thickness, oiliness, sweatiness and hairiness. The palms of your hands and the soles of your feet have the thickest skin, with an extra layer of cells in the epidermis. They have fat pads under the surface and, though they don’t make hair or sebum, they produce lots of sweat. Your armpits, in contrast, are very hairy and produce lots of oil, contributing to body odour. They also have a higher ph than the rest of the skin, making it much easier for bacteria to grow. The most delicate skin on your body is on your eyelids. At just 0.04mm thick it is 40-times thinner than the skin on the soles of your feet.
