Wrinkles behind lower lips and insdie le

I am on htn medicines 5mg a day since 8 years. Aztolet 10mg for cholesterol to a short schedule. Since a month taking some tablets for nail fungus after ingrown nail surgery. It's temporary. My vitals are normal. Weight 77.6 I have typical IBS-C .I am taking occassional probiotics when it seems worst . In a week course as per my gastroenterologist . ISSUE IS since long I am suffering from some wrinkles / non bleeding wounds at inside lower lip and left edge of inside mouth. First I thought it's because of sensodyne repair paste and changed the paste. Even though inside lip is very very sensitive and wrinkle / no bleeding wound is repeating. I am applying ora fast gel but no use. It goes in 2 days and repeats. Please suggest me any supplement which won't cause constipation.
