I always asked dermatologists if I had Actinic Keratosis, but they said no. I thought I had skin cancer since I spent my summers sunbathing (without sunscreen on lips) when I was a teenager. I even applied this cream on my lip that made cancer cells show up if they were hidden in your skin. Thankfully, no cancer cells showed up.
I think I had EC longer than most people here. So, I want to give hope to you that your lips can heal after decades of EC. Well, unless you have Actinic Keratosis or skin cancer, but a dermatologist can determine that.
By the way, the acidophilus can help to fight cancer cells.
