I have this makeup cream. When I wash and rub water over it, it leaves a very fine layer on my skin that is pigmented. When i scrape it with my nail i see it come off. How to know if a substance prevents water from reaching the skin or not. Jazak Allahu Khairan

Before that I need to know if you suffer from waswas or not.
