Unfortunately, I don’t know the fields well enough to recommend something from direct experience…but I’m sure others’ recommendations along those lines are great.
Having said that, look for a good calendula cream. In the US I use a brand called Boiron (they’re from France actually) for any skin & all conditions. It comes from marigold flowers and has great healing properties for skin. If you can, use that in conjunction with a good vitamin spray (you can make a good spray of vitamin e, vitamin c and COQ10 using a good mineral water as a base).
EDIT: Oh! And silver spray…Silver would be great because it has antiviral, antifungal, antimicrobial and antibiotic properties, if I’m not mistaken.
I hope that helps!
