Wa `alaykum As-Salamu waRahmatullahi wa Barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Answering your question, the late Saudi scholar, Sheikh Ibn Baz (may Allah have mercy on him) stated:
There is nothing wrong with using them for one who is fasting, but makeup should not be used if it will cause harm to the face. (Majmu` al-Fatawa, 15:260)
Almighty Allah knows best.
