Can you use apple cider vinegar for Melasma Treatment? (photo)

I've used hydroquinone up to 10%, Triluma and Obagi C Clarifying over the past 2 yrs with no luck treating upper lip melasma. I read apple cider vinegar can help and concerned to keep using hydroquinone due to the side effects with long term use. Can anyone tell me what I can do? Everything I've read says IPL makes melasma worse. The doctor I use for skin care/laser hair removal is concerned to make it worse if she treats it with anything other then topical creams. Makeup makes it look worse!
