The best way of dealing with seborrhœa is according to _Spietschka_ and _Grünfeld_ the following: The washing is best effected in the evenings, when the skin will not again for many hours be exposed to the fresh air, to wind, or to dust. Pour into a basin about a pint of warm water and add from one to two teaspoonfuls of spirit of soap (equivalent to the linimentum saponis of the British Pharmacopœia) or as much soft soap as can be taken up on the end of a table-knife. The water is then stirred vigorously till a good lather is formed, and with the water and the lather the face is thoroughly washed. The skin must then be carefully dried, and thereafter it is well to smear it with some greasy material, such as boric vaseline, in order to prevent the plugging of the pores with dust, and to protect the sebum subsequently exuded from dessication. On the next day the washing should be repeated only if the face has become covered with sebum within an hour or two after the first washing. If the exudation is less free, the eyes only should be washed with fresh water, whilst the rest of the face should not be wetted, but merely be wiped with a dry face towel lightly dusted with toilet powder, in order to remove any accumulation of sebum. The skin of the genital regions must be carefully cleansed, especially in cases in which there is a tendency to hypersecretion of the sebaceous glands, to eczema, or to herpes progenitalis; subsequently it should be powdered, and pads of absorbent cotton-wool dusted with toilet powder should be placed in the labial furrows.
