Is Biafine an Effective Treatment for Melasma?

I had an IPL 6 weeks ago for melasma, and got severe burns. I have hyperpigmentation badly on one cheek from this and am wondering if this will go away, and if so, how long will it take?

My melasma is worse now. What can I do to fix this? I am currently using biafine on this, is this what I should be using?
