My friend has really hair eyebrows lol, and he has to pluck them twice a day here and there just to keep the shape or whatever, He cared about his looks and a lot of girls like him lol. Anyway, he's worried that doing this twice a day every day will eventually cause the skin in that area of his face to sag in 30 years or will cause the skin to do something bad! What do you think?

irrelevant jokes can stay at home with the children please. Thank you =D

Well that's seriously excessive, but no it won't cause them to "sag" as you put it.

Thank you!
