Does the neck stretch when you get older im 17 and going to a tattoo behind my ear but very skinny worried if skin will stetch?

The skin's elasticity does tend to decrease with age. However, it's important to remember that everyone's skin ages differently, and some people may experience more skin elasticity loss than others. At 17, your skin should still be relatively elastic, and it's unlikely that the neck skin will stretch significantly if you get a tattoo behind your ear. However, it's still a good idea to consult with a tattoo artist or healthcare professional before getting a tattoo to ensure that it's the right decision for you.
