Moles appearing after mt2

Hi all, I started using mt2 for close to 2 weeks at 50mcg dose before bed and I broke out with moles : sunspots on my head. I stopped using instantly. My questions is are these likely to go away and if so, how long?

I’m annoyed as I was actually getting colour but I don’t want to break out with any more.

Any advice on how to avoid this or is this just the inevitable

The ones circled were already there

Thank you
