Melasma Remedies

Hi there, Well I have been using Apple Cider Vinegar diluted in 1:1 ratio of water and Apple Cider Vinegar for a week. I also use flaxseed oil on my skin once in a day, my melasma on side of my cheeks has become lighter in colour but there is no peeling off the skin. I have read so much benefits of Apple Cider Vinegar on treating melasma and many people claiming complete removal of those dark patches.

Well my melasma is just a year old and its not very dark also but I dont see it going away. I will be continuing this mixture and lets hope for the best... Can anyone help me.... can I use Apple Cider Vinegar mixture during daytime? and what else can I do to treat my melasma asap.
