Hyperpigmentation caused by birth control?

Hi ladies!
I have had the Nexplanon birth control for years now. This passed year I have noticed hyperpigmentation above my top lip and it looks like as if I have a mustache :sob: which I don’t it’s just my skin is darker there. I believe it’s from the implant. How’s anyone else had this issue? If so did you just deal with it or switch to a different BC to get rid of it. Did it ever go away? I’m thinking about removing the implant and giving it a few months and hopes the darkness will fade and change to something else. I’ve become so self conscious about it.
