Distribution of Thin versus Thick Skin Across the Body
Quick fact
Thick skin is found only on the palms of the hands and soles of the feet, but it is actually not thicker overall—its epidermis is thicker, while the dermis is thinner than in thin skin.
Why this is interesting
You've probably noticed the soles of your feet are tougher than the skin on your arm, but have you ever wondered why your body has different types of skin in different places?
