For approximately 7 years now I have a purple ring outlining my lips (on the lips, but at the edges), EXTREMELY dry skin on lips, and little clear bumps on lips. The skin on lips is so dry that I have to put vaseline or bag balm on them every few mins. Gets much worse when I eat anything salty. Have been to different doctors, with no result. I am gluten and lactose intolerant. My family has a lot of autoimmune diseases/conditions. Co-worker just told me today she had a purple ring around edges of her lips, and very dry lips and her dermatologist told her was toothpaste lips caused by ingredient in most toothpastes. She switched to AIM toothpaste, and dr. gave her meds., but was many years ago and she doesn t remember what meds. Any advice would be extremely appreciated - can t take this much longer. Thank you!
