Not everyone is naturally beautiful. Not every bas Yisroel is a pretty girl with perfect skin, and perfectly blushed cheeks. Instead of saying assur, assur, assur, one is wiser to ask their Rov a shailah about how something might possibly turn out to be muttar. According to the rabbanim who mattir certain types of powdered makeup, their instructions are to use pulverized powdered lip color, applied with a totally dry brush used for that one color only, and specifically set aside for Shabbos. A clean, new brush may be used for the eye powder, face powder (like Bare Minerals, though there are “kosher” companies that make a line of makeup for Shabbos), eye “liner,” and so on. You should definitely ask a Rov and not the people here in the CR. What I told you was straight from the pamphlet with the appropriate p’sak of how to apply Shabbos makeup.
For those of you who don’t hold by even such heterim (and do not disparage the rabbanim who paskened the heterim), by all means do not wear makeup on Shabbos. Also do not eat cholent on Shabbos, as there are Yidden who believed that hot food on Shabbos was also assur, and were not interested in understanding the heterim for how to set up a cholent pot k’halacha.
