RIYADH: The resurgence of ithmid in the Saudi market among the youth has sparked interest and discussion in recent months. Ithmid, also known as kohl, is a type of eye cosmetic that has been used in cultures the world over. It is made of ultra-fine and homogenized powder containing a mixture of minerals or elements. Ithmid has a long history of use in the Arabian Peninsula and other parts of the Middle East. But for Muslims it holds special significance because it was used by the Prophet Muhammad for its benefits to eye health.
