My wife uses Thermal Spring Water spray (by La Roche-Posay), it was recomended by her doc....it works great for her.
She is on her 13 Chemo...normally her faces is all red during the second day of Chemo. After the chemo she also gets that nice "sun tan" color, plus some rush.....she is handling it with this spray, plus some specialized skin lotions. She is on Folfiri+Erbitux.
Good Luck
