Why a bath oil?
A bath oil protects dry or rough skin and restores and protects the natural skin barrier against (further) dehydration. The oil mixes with the bath water, after which the oil can penetrate the skin. Your skin will thus remain soft, provided with a layer of oil so that the moisture can be retained well. This protects the skin from drying out.
How do you use bath oil?
First of all, do not make the water of the bath too hot. Boiling and warm water dry out the skin even more. Add a few drops of bath oil to the bath water.
