This question's pretty much eternal!

With dermatologist Dr. Sandra Lee (a.k.a. YouTube star Dr. Pimple Popper!) on hand, our viewer Tara made a confession that pretty much most of up can cop to: As a pre-school teacher and the mother of two young boys, she's often so exhausted by the end of the day that she goes to sleep with her makeup on.

(Been there, Tara — been there!)

BUT is falling asleep with your makeup on really as bad as everyone says?

According to Dr. Lee, the answer is — it depends!

"It's not so bad," she says. "I confess, I do the same thing every now and then! It really has a lot to do with our skin type."

Dr. Lee says that if you have oily skin — or if you have a job that gets your face dirty, or if you wear heavy makeup on a day-to-day basis — then yes, make sure to wash your face every night. You don't want to tempt those breakouts!

But, she says, if you have dry skin — which she herself says she has — an extra wash can dry your face out even more.

So it really is a case-by-case basis.

"It's always a good idea [to wash]," says Dr. Lee. "But if you forget, don't knock yourself down."

Gotta say, this one feels like a win!
