What age did you let your daughter start playing with makeup?

My LO is 4. I don't wear it often, but she has seen me 'get fancy' for work occasionally. She REALLY wants to play with it and put on makeup. I'm kind of pushing it off and distracting her for now, more because all my makeup is old AF, most is older than Covid, (and I don't want to give her pink eye!) But I'm curious about y'all's opinions. Did you let your daughter play with yours, and at what age? Did you buy her her own 'play' makeup, or real stuff?
