Hi,kindly taper the use of your above prescribed medicines as long term use can lead to reddening, thinning and drying of your skin. Whatever problems you are facing is just because of continued use of these products. As your pigmentation has already gone, use cetaphil
moisturising lotion or elovera lotion to treat your dry skin
. Use a mild soap free cleanser. As melasma has tendency to recur, use a good sunscreen, take oral vitamin c
and antioxidant supplements to prevent it from recurring. You can also use mild vitamin c, kojic acid
or arbutin based creams as maintenance therapy. These topical medications are sage and have no side effects as such even on prolonged use.The white patches that you seem to have are due to use of lomela and demilan, once you will discontinue its use, your skin colour will return to normal in few days. take care.
