My mom really screwed up her eyebrows by plucking them when she was young. She plucked them so much that they never grew back
So, she has permanent eyebrow. They look perfectly natural, too. She also has the permanent eyeliner and lipliner. She says it REALLY hurts to get the eyeliner done, but she wakes up beautiful every morning. All she has to put on in the mornings is lipstick and mascera.
The permanent eyebrows do fade somewhat overtime. So, you will have to get them touched up. Aging will not affect them. My mom has had hers for years and they look as good as the first day she had them done.
Since my mom screwed up her eyebrows so bad, she made all 3 of her daughters (that includes me) get electrolysis on their eyebrows starting at a young age. I started going when I was 13 and I have not had to pluck or do anything to my eyebrows in years because electrolysis is permanent. I also got my upper lip and my sideburns off. I highly recommend electrolysis. It is, afterall, the only proven method of permanent hair removal.
