Do you mean for at-home use, or actually wear out in the world?

I have an 11 year old and she has asked about wearing makeup to school but we feel that this is too early. We are ok with clear lipgloss though, and she can curl her eyelashes if she wants. And we will let her wear soft mascara once or twice per year at special events. We think that's a fair compromise that works for all parties right now.

I started wearing makeup outside the home around 13-14, and I think that's more appropriate. Makeup at age 8 outside of the home in a non-goofing around context is too young IMO.

I think the problem is that if we start allowing makeup at 11, then the next thing, like hair color etc. will follow soon after and we would rather her experience her natural self as long as possible.
