The epidermis is the outermost and thickest skin layers. Its thickness at the sole of the foot is about 1.5 mm. The skin is able to be updated. For example, in adults, this process occurs every month, and in newborns - for 72 hours. The update is carried out due to the basal layer (the deepest part of the epidermis).
