If you read the title and wondered what "Chub Rub" was. . . CONGRATULATIONS! You're probably in possession of either:1) a penis, and/or 2) thighs that don't rub together. In which case you might not know what "Chub Rub" is.
It's chafing cream. In my case, it's Monistat Chafing Gel. You would normally put it on your thighs before particularly long, hot or vigorous day wearing a dress or skirt. It prevents your thighs from catching on fire due to friction. If you've ever had a campfire break out between your legs while trekking through a city, you should become familiar with chafing gel. It's awesome.
However, it came up as an alternative to the wonderful but expensive Smashbox Photo Finish. At first I thought it was a joke. But then it made sense. So I tried it. And I LIKED IT. I haven't had a breakout since I started using chub rub on my face. It prevents my makeup from agitating my otherwise troublesome skin. And it's $6 vs. the $36 per tube for Photo Finish.
There you go. My internet-born secret from six years ago is shared with you. And for those of you who read this based on the title and were expecting chub rub to be something completely different, well, that's probably why we're friends.
