Cosmelan MD or Rejuvenize Peel for Dark Skinned Woman with Melasma?

I have had the Cosmelan MD applied for over 2 years; pretty consistently, and use 50spf sunblock on my face. I have severe melasma on my cheeks and upper lip . I am of mixed race (Halley Berry color with a sensitive freckle face), and suffered terrible IPL burns nearly 3 years ago, trying to address melasma. Although, the Cosmelan MD works to keep the melasma at bay, it is not as effective as I would like, and it is pricey. I see the Rejuvenize Peel advertised and wonder if it is worth a try.
