I tried protopic for three weeks, starting with the .1% for two weeks, and the .03% for the third. It made my lips very sensitive to the sun, and gave them a constant burning sensation. It also make new skin hard to remain intact as I was disrupting it by putting on the ointment, and sometimes the skin would turn white (ugh!). After those three weeks I've decided I like my lips better when they are dry, and there was no positive effect of the protopic- although I'm glad I tried it so I can now cross it off my list. Best of luck to you, but be wary of the sun if you try it!
