My brown spot on my face is darker than before and has texture. What should my next steps be?

I have a brown spot on my face, smooth to touch.I have had it for 10 years now. About 4 months ago I started IPL treatments on my face to lighten it. It darkened and flaked as expected, but never lightened. After 4 treatments I decided to stop IPL because it was darker than before and now it had texture that wasn't going away. It has now been 7 weeks after last treatment and it still has texture. My aesthetician doesn't know why this has happened. Is it possibly skin cancer or melasma?
