The ruling on using eye drops and kohl while fasting

Question:
The questioner asks: Is it permissible to use eye drops while fasting, as well as applying kohl, and using substances with a strong odor, such as hair removal cream, or hair dye that is close to the face?

Answer:
As for using oils on the skin or on the head, there is no harm in that. There is no harm in using oils on one’s skin, or for a woman to use them on her hair. This is not prohibited and does not affect the fast. As for using eye drops or kohl, this is a matter of concern. A Muslim should be cautious with his fast and use them at night, putting the eye drops and kohl in at night, not during the day, because they may seep into his throat, and a person may taste them in his throat, so he should delay them until night. Yes.
