I found this phrase below on the web:
As far as gels are concerned, I am not a big fan. If you are not a woman that is going to keep up the maintenance don't do it. If you are willing to go and maintain the up keep, then I say go ahead, because gel isn't the healthiest overlay for your nails. They will make them dry and weak.
Do both "keep up" and "up keep" have exactly the same meaning?
