hi You have a condition called Melasma/Chloasma. Its difficult to cure it completely and sometimes it can come back again after clearing. Its a frustrating condition bot for the patient and doctor equally. Anyways their are mutiple modalities available: Ideally you should use a broadspectrum sunscreen with all forms of treatment, which protects you both from UVB and UVA rays and apply it every 3-4 hours. A treatment plan which combines exfoliation of already existing pigment with that which reduces synthesis of new melanin works better than undergoing just exfoliation of existing pigment(like you are undergoing glycolic peels) Demelan contains glycolic acid, which is exfoliating and will help reduce existing pigment and it contains kojic acid and arbutin, both of them help reduce synthesis of new pigment. So its a logical combination. always usea broadspectrum sunscreen with any form of treatment
