I have never tried bath oil in Marc's bath, but I have used lavender bath salts. I once read somewhere that lavender helps decrease the redness. I bought the bath salts and put them in Marc's tub three times a week. I did notice a difference in the appearance. His skin felt smoother, too. Once out of the bath, I still applied his cream-aquaphor or Neostrata's Problem Dry Skin. Let me know if you try the bath oil.
