Can I change the skin pigmentation of the melasma?

Can I change the skin pigmentation of the melasma?

Ever since I started wearing a mask,

The skin around the lips has gradually darkened and become discolored.

Is it okay to use a laser??

I'm afraid I might mess up, so I haven't done it...

It looks really bad if I don't wear makeup, what should I do?

Can I use it with a dark spot ointment??
