The chemical or medical statements I could not check at home, but I can comment on the subjective impressions of relaxation, mood elevation, and the care emotion.
Since I have to say that the question of whether odors can lighten the mood, well first is faith and a matter of taste only once. Clear, well no stench brightens mood, but an intensive Blütendruft (as in this cream bath) should also like for now. In addition to baths should already have a positive impact in itself on emotions. I would therefore not push alone on Cremebad.
So let's be realistic.
And realistically, I can give the Cremebad four stars for the soothing care, even if I'm the most gentle care feeling not so sure.
