I used to never considered blush one of the major products in my makeup regimen and there was a time that I wasn't wearing it regularly at all. But here's the difference between cheeks with and without blush:
The change is subtle, but there is a change. There's a certain warmth and glow that rosy cheeks add to one's face. I think I look rather cold and colorless without a pink flush. Given the option, I would prefer to forgo eye makeup rather than blush. So, is blush absolutely necessary? I don't think so. I guess I look OK without it, but if I were in a rush and had to skip something, it wouldn't be the first thing I'd leave out. But this is just my personal opinion. :)
Hope everyone's having a great Sunday! It's back to the books for me!
