the Skin's an amazing organ just like you said it's the largest organ and the largest Dynamic organ we have in our body you have new skin brand new skin every 28 days so the surface of your skin turns over about every month now the stem cells which are in the lowest portion of our epidermis uh remain and they generate the skin cells but you have brand new skin the same way you have new gut lining every 28 days it's amazing for many reasons because the skin is one of the few organs that can regenerate because of this so you can grow new skin you can test things on skin if your skin gets injured it will regenerate and heal itself whereas many other organs cannot do that and because of this it also allows us to use it as a model platform for studying diseases of all kinds
