“Negative Side Effects from IPL for Melasma”

I had 2 IPL treatments om my face for melasma. Months following the 2nd treatment I got white polka-dots all over my face. They are clustered on the rt side of my forehead and below both cheeks. They have not gotten any better after 1 year. I have used Tri- Luma, chemical peels every 3 weeks and tons of sunscreen. I also still have terrible melasma. I want to know if the white spots willever go away or what I can do. I am considering Active FX. I have also considered Cosmelan but I read the solution contains 8% HQ and not sure how safe that is.

Will the hypopigmentation improve with time and if so, how much time? Should I consider Active FX. No one where I live seems to have an answer.
