I'm diagonsed with lichen planus pigmentosus. Last year December 2017 , I took dapsone daily for some 15-20 days and later I got fever so stopped it as doctor suggested. Later in Jan 2018 I took metrogyl 3 tablets per day. I took this also for some two weeks. Later I started noticing my skin became very dry , loose, wrinkled. I could  literally  see cracks on my skin in my hand and very wrinkled . I stopped all the tablets and not been taking anything since then. However I still find my skin very dry and loose. My skin wasn't dry at all before taking those tablets. I'm not sure how to over come this sideeffect of my skin. How can I get rid of this dryness? I use  moiz moisturizer and a sunscreen lotion on a daily basis since two years. Currently I do not take any medication for lichen planus at all . How can I do to get back my original skin?
