The Muslim woman is not permitted to display her adornment before non-mahram men (i.e., those whom she is permitted to marry), and she is to restrict her adornment for her husband. She is allowed to apply makeup after performing ablution or ghusl. But if she applies makeup before ablution or ghusl, she has to remove the makeup in order for her prayer to be valid.
The prominent Saudi Islamic lecturer and author Sheikh Muhammad Saleh Al-Munajjid</b> ;states the following: If a woman performs ablution then puts makeup on her face, that does not matter, and it does not affect her ablution or her prayer, so long as the applied makeup is not najis (impure), because purity of clothes and body are essential for the prayer to be valid.
However, it should be noted that it is not permissible for a woman to wear makeup in front of non-mahram men. If she does that and then prays, she will have the reward for her prayer but she will have the burden of sin for tabarruj or wanton display.
With this in mind, the Muslim woman is also allowed to use kohl but it is not permissible for her to show any of her adornment, whether kohl or anything else, to anyone other than her husband or mahrams because Allah says, (and not to reveal their adornment except to their husbands) (An-Nur 24:31).
