Praise be to Allaah.
Kohl does not break the
fast of either women or men, according to the more correct opinion of the
scholars, but using it at night is preferable for one who is fasting. The
same applies to other things that are used to beautify the face such as
soap, creams and so on, which has to do with the outer layer of the skin.
That also includes henna, make-up and the like, but make-up should not be
used if it will harm the face.
