I didn't start trying makeup until I was 18-20, and didn't start wearing it frequently until I was in my early 20s. Now I'm in my mid 20s and I can't even fathom going to work or seeing people or having my photo taken without it. I've officially crossed to the dark side.
I have serious issues with my appearance, I'm insecure with or without makeup, because of course makeup can either look really good or really bad. I didn't even know how to wear it when I first started, I literally just put foundation on and mascara and was done. *Vogue*
But now that I've really got into it I do actually enjoy it, I find it fun, I love looking up different techniques on Pinterest about how to apply things properly and make it look good. I don't regret getting into it, but I do wish I wasn't so reliant on feeling more confident with it.
You don't have to wear makeup if you don't want to, and you don't have to listen to other people questioning you if you do decide you want to wear makeup.
