There are many cases where this is simply an unintended consequence of the multiple layers of fake tan or a spray tan applied on top of each other. Since fake tan is a liquid, when it is used in large quantities, it gives the skin a shiny appearance because it is a liquid. In addition, bodybuilders will also have to remove all the body hair from their bodies, as this is the only way to achieve the desired smooth and shiny appearance. Also, some people use oils to achieve that shiny appearance and to make their muscles appear more defined as well as to make them appear to be more limited.
