New Use for B&M

I've been teaching outside in the AZ sun every day for 4 straight weeks, and am properly sunburned at the end of every day. I've been showering after work and ran late a few days in a row, getting through the prep, but having to rinse off my Solstice sample. After each day, my face felt healed. So Bannister and Mann is great at curing sunburn.
I'm guessing it's the tallow and lanolin, but does anyone have an explanation for this.
