My mom is a youtube make up artist. She is basically a artist of the human body.
so that means she does make up for the whole body and not just the face?
yup, she's even  won an Academy Award for best makeup and hairstyling.
that's neat and a very worth accomplishment
She used to be employed by a large production company since they have their own in-house make up artists.
so does she used to work for movie studio and now is a freelancer 
Yes basically, I think she wants to retire but doesn't want to completely stop.
seems like a type job you can do all you life as long as your eyes are good
