Hi doctor, Around my nose ( at the corner of my nose) is getting darker, it s been 2 years. I ve never actually do anything to it, just wash my face sometimes at night, and apply moisturizer (if i remember or if i m not so tired) i dont do make up as a daily routine, just on a special occasion, not even a bb cream, foundation ect. Sometimes it feels so dry and flaky, and itchy so i ll just apply moisturizer. And lat month down my lower lips start to getting black, what should i do?? :(( Thankyou so much doctor.
