Mix in a saucer the white of an egg and the juice of a lemon then add enough Fuller's earth to make a stiff paste. Cover your face with that and remain quiet for a quarter of hour, by which time the paste will have dried and be feeling very uncomfortable. When you feel you can't bear it longer remove by sponging in warm water. Dry on a towel, apply an astringent, vanishing cream, if you like better still the lemon and milk wash.
