Oily Skin is it removing toxins?

and what type of toxins would these be?
what we consume? breath? or a vast amount that the body is trying get rid of, does oily skin take a part in this eliminating process. i know sweat also plays a part i want to know if the oils from the scalp do the same? especially if the oil is excessive? i do have Amalgam fillings 7/14 and i am having them removed. i also want to know if mercury is being released through oily scalp.
