What's the difference between saturation and vibrance in Lightroom?

Question

Both options affect colors in a similar way, but I can't figure out the difference.

Answer 1

They both intensify colors, but vibrance does so in a more intelligent way, mainly affecting the more muted colors, not the colors that are already saturated. Vibrance will usually get better results.

Answer 2

Vibrance also does a better job of protecting skin tones. And don’t think that you have to choose one over the other sometimes a little bit of both works well
