I posted a picture of what's happened after about 5 days. Notice the return of vertical lines! The whitening is a side effect of the vinegar and usually goes away after about 20 minutes.
I should note that, in order to prevent a buildup of the chitosan/vinegar gel, the mixture does have to be removed every now and then (and you have to be very careful with the underlying tissue; although, it is at least a little bit resilient). Interestingly, tonight, when I removed some of the stuff, the underlying skin had a..."squeaky" feeling, something which I haven't noticed in a very long time.
