Thanks for the query. Long term usage of any disinfectant can cause such pigmentation. The best way is to consult a Dermatologist for proper assessment and diagnosis. Treatment can then be instituted. It looks amenable to treatment by depigmenting creams and a sunblock cover. If left alone, it may take few months to fade.
