Dianne 35 is hormone based contraceptive it may cause pigmentation as a side effect. But pigmentation can occur due to variety of reason like lichen plans, post inflammatory, amyloidoisis etc. Proper examination is required for diagnosis of the cause. I encourage you take visit to a qualified dermatologist for examination and proper treatment. Visit a dermatologist for some clinic based procedure like chemical peeling and laser. Hope this helps.
