I think you are doing really well thatcillagirl. I have been travelling for two weeks (just back now) but I have a blog I post photos on weekly and much like you I'm attempting to leave alone + moisture.
So far I have been using calendula ointment for the longest time but it requires constant applications all day to see the best improvement in the lips. I stopped using aquaphor because a lot of it goes inside the mouth I ended up eating it and the taste of it overnight is just horrible. I think we just have to be focused on leaving the stuff on there and not disturbing it as much as we possibly can but it is so so hard. My days out would involve having to find somewhere to apply the ointment and I carry a mirror with me to make sure there are no lose bits of skin hanging around on the lips.
It is hard the skin being so delicate. I might trial a boost healing method where I apply the aquaphor literally every 15minutes like daniel miller said, but this is on average 40-50times per day which requires a rediculous amount of effort. In the end perhaps I will have no option but to follow his advice exactly lol.
Another thing is to get it right inside the mouth where the teeth are.
Anyway I'm really happy for you and I think it depends if you follow daniels every fifteen minutes everyday and allocate a few days where u dont have to leave the house or eat or drink very much at all you might find you get a huge kick of progress.
I have noticed vertical lips starting to form now, they are very very shallow but this is something.
