Halobetasol
"I had sores on my palm that just would not heal for several weeks.  Finally used Halobetasol Propionate Cream 0.05%.  It healed in about a week.  I have other less powerful creams and so I only use this cream when nothing else works.  Once it works, I switch to less powerful creams for awhile.  I then switch to using Dove Sensitive skin and Vanicream.  It is really powerful but should be used only when nothing else works."
