I haven't tried the Tacrolimus ointment (but I'm going to look it up), but I have been using Lubridrem's Intense Skin Repair ointment for the past 2 months and it's really helped my condition. I've had this a long, long time, so it's great to have normal-feeling lips again.
I'm also eating really well and drinking lots and lots of water; so I can't attribute this success to any one thing in particular. But I suggest anyone give the Lubriderm ointment a try, since it's really been helping me.
The thing that has amazed me is the return of the elasticity of the transitional lip skin. Before I was doing all this, that area was either peeling or drying/crinkling up, getting ready to start the plaque growth and peeling cycle all over again. Now that skin has an elastic texture it didn't have before.
