So basically I have been travelling for the last 2-3 weeks hence no updates.
In this time I have been applying the calendula ointment 5-6 times per day. I am now applying it overnight as I don't think the skin heals well enough without protection. The bits of white gunk you see is not necessarily dead skin it is a build up of calendula ointment.
All I am doing is following the redness as an indicator. I am careful to not go one day without applying the barrier or miss an application. If redness return it means the area needs more protection and I'm in two minds whether to switch back to the steroid ointment as a barrier, which I may do at some point.
You cannot see from the photo but underneath the layers of calendula ointment there are lines forming, they are very shallow but they are there.
