my lips are painful and itchy, after two weeks, i noticed, they are darkening around the liplines. I tried lip balm, after quite an hour, i will feel the pain again and the itchiness. I have no change of diet that would cause this nor drastic change of weather. i have new lipstick i used since june but the itchiness i felt started only about the middle of June. I am not using lipstick for a week, but still the condition persists. My lips are not chappy or flaky thoug, just painful and itchy and getting darker. I don't drink coffee nor smoke. Thanks.
