I have roasea and did not like the topical antibiotics as they make you sun sensitive. I spread the honey on, leave it 5 to 15 minutes then rinse off. It comes in several strengths. I would start with the 5 MU (manuka units) and they say nothing thing stronger than 10 MU on your skin. I use the 10. It has a creamy consistency with tiny soft/easily melted crystals. It tastes slightly bitter and smokey.
It is honey made from Manuka tree flowers (where Tea tree oil comes from).It comes from New Zealand and I paid $25 for a lb jar a couple of years ago (a little goes a long way). Just looked it up on the Wiki and apparently there is a lot of adulterating going on lately so research the packer. I got mine at the Whole Foods.
My child has Morphea Scleroderma on their left side. I made a massage ointment to loosen/soften the resulting scars. This was suggested as an eczema treatment. Equal parts by weight: manuka honey, olive oil, and beeswax melted then whisked together as it cooled. it was used in conjunction with oral and injected steroids. Currently in remission (knock wood)
Good luck!
