Best Melasma treatment

[sangria]

I'm looking at the following to treat some melasma on my forehead and cheeks but I'm at a loss on which to try. 

La Roche Posay Mela-D
Glo Skin lightening Serum
Glytone dark spot corrector 
PCA Skin pigment gel 
R&F Reverse toner and treatment

Has anyone had personal experience with any of these? I need something that works but doesn't break the bank.
