What is the reason for the following properties of the palms of our hands? (info inside)?

Question

The fact that no hair grows on it.
Or the fact that even people with darker color skin have light colored palms.
Or even the texture of it differs from the rest of our skin.

Answer 1

no hair grows and it is a different texture and color because it is a different type of tissue. It is thick skin, which has a thicker layer of keratinized cells. This gives more protection to deeper tissues, allowing us to use our hands to grip things.
