i think it is good at 17 if you are talking about full make up but it is okay to wear lipgloss and blush on if you are 13 and just keep it simple make up are use to enhance you to be more beatiful not to make you look like a monster
I think maybe 17 or so, if you want to apply fuller'heavier makeup :) but if you wanna wear lip-gloss or concealer (if you feel innsecure about a spot or scar) that's fine too if you're younger like 13-14 :)
I mean just like some not a ton. Like maybe lip gloss or something. Maybe at like 15 or so at a fancy occasion but try not to over do it.
