Try Physician's Formula products, they seem to be pretty mild (from what my daughter tells me).
You might also try Ponds or Neutrogena, both companies have been around for years and may have products which are specifically geared towards sensitive skin.
Meanwhile, if you have a health food store nearby, you might also check there. To the best of my knowledge, many natural products may contain less irritating ingredients (no chemicals), so that may help someone in your position.
Good luck!
