The only part of my face that i breakout on is my chin. No matter what i do, or what time it is, i have a couple pimples on my chin. They always turn into whiteheads, sometimes their big & painful, im just sick of it. They take forever to get rid of too! And i have so much hyperpigmentation scars from them also. What can be the cause of this? Its not just before/while on my period. What can it be besides hormonal & how can i treat it? Supplements?
