Will LPP ever go away? Home remedies?

Im diagnosed with lichen planus pigmentosus after a biopsy. It's been like two years I've got this. Started with hyper pigmentation in underarms face n neck. Now it's spreading all over my arms n face. My hands , neck n face has dark patches all over. 1. I started with tacrolimus and corticosteroid cream.. Used Sunscreen lotion and avoided exposure to sun for few months. 2. Then underwent UVB for 3 months after which I started becoming darker. 3. Took vitamin and antioxidant tablets for two months along with tacrolimus. 4. Now using only depigmentation creams like melasma n depiwhite on face and hydroquinone 5% soln on hands n also having xamic 500 tablet for the past 3 months. But I noticed new ones haven't stopped. Dark patches are increasing on my hands n face. 1. Is there any way to stop/control this disease? 2. Will the dark patches eventually fade atleast on a long term atleast ? 3. Will I ever get back my old original skin? 4. Is there any home remedies? i'm very depressed.
