I'm starting Week 4 of my protocol (same as Week 2)
My lips are still soft. Yesterday morning when I woke up, I felt some loose skin on the right side of my lower lip, and when I looked in the mirror, indeed there was a layer of skin about half inch wide that apparently had begun to separate during the night. The loose skin was very thin/delicate and completely fell off while doing my protocol after breakfast, leaving a smooth lip.
Today, the skin on my lips feels much stronger, and the sensitivity is much less. The white "line" that used to form between my lips is so thin now that is hardly noticeable. I'm even getting back the vertical 'ridges' just like normal lip skin. Slowly but surely, my lips are feeling and looking practically normal. Yay!
