Why don't the palms of our hands and the soles of our feet tan or burn?

Well there is an extra layer of skin on the palms and the soles. It’s called The Stratum Lucidem. It’s privies thickness to the skin. In the lower basal layer of the skin you have your melanocytes which vary in amounts depending on race, the more melanocytes the darker the skin. The melanocytes have a harder time migrating through that thick keratin layer. There is still some color but it’s just lighter. You can still burn the skin on the palms and soles with UV light but they don’t get as dark cus of extra layer of skin.
