I had already talked about actinic cheilitis while mentioning vermilionectomy done in this kind of cases but she didn't seem to react and none of my derms thinked about it. I think the biopsy would have shown if our lips were also affected more deeply. Then, this cheilitis usually affects 40 years old men or older.
Maybe the picking played a role and the sun lightly damaged this sensitive area superficially.
