I concur that melasma can be difficult to treat, so it’s necessary to tamper your expectations as to how much improvement you can expect.
I’d generally be wary of anyone who promises that X or Y treatment will get rid of melasma completely.
As both Dr Israr and Dr Rui Ming mentioned, it may require a combination of treatments before you see improvement.
I’d suggest to have a doctor have a look at it and to ask him realistically what % improvement you can expect, and how many treatment sessions will be needed.
Cheers
