I never used to wear it. Then I started wearing it to work. Every day. Some days I think "WHY!?!? I could sleep for that 10 min!". But I'm told I look washed out when I don't wear it... by people who knew me before I started wearing it to work! Having said that, my make up regime consists of foundation, eyeshadow, mascara, and clear lip gloss. That's it. No concealer, no blush, nothing like that. If it takes more than 10 min (ideally 5 or less), it's not going to happen!!!

ETA: I only wear it on weekends if going somewhere special.
