I've been using palmers cocoa butter lip balm and haven't noticed any improvement. In fact one night when I went out, no matter how many times I put it on my lips, they would stay chapped. I had to ask my sister to user her chapstick the whole night. It sucked.
Healing, are you done using Zyclara?
I think that my lips have been improving with the Imiquimod, aside from the weeping that's been happening on my bottom lip where it meets the gums.
