At 48 years old, I had a problem with eyeliner smudging. I've worn black eyeliner since I was old enough to wear makeup so I decided I would make it permanent.
It looks good, and while it's nice to not have to bother with eyeliner, it bothers me to never be able to see myself without any makeup at all. Ladies, really think before you leap. You will never, ever see your fresh faced self again.
Is it awful, no, do I wish I hadn't done it? Yes and no. If I had it to do again I would chose not to.
