Benefits of going without makeup?

Ren
So this my third day of not wearing makeup, for a few reasons: just got a nose piercing so I would have to avoid that area anyways, it's decreased the amount of time it takes to get ready for the day significantly, and just curiosity! 
SO, I was wondering if anyone has gone a period of time without makeup, for how long, and what kinds of changes did you notice to your skin? Thanks beauties!!
