Your epidermis varies in thickness from 0.05 mm on the eyelids to 0.8 ± 1.5 mm on the soles and palms.
It’s amazing to think that your skin is jam-packed full of millions of cells and is still only about 1-2 pages of paper thick! The epidermis acts as a renewable protective guardian for your body, with complete keratinocyte turnover about every 28 days (although this process can reach up to forty days in older skin). Consisting of 4 horizontal layers (with a 5th on hands and feet), each layer represents differing stages of cell activity and keratin maturation.
