How do you manage a dull complexion?

Since it's the weekend, I slept in for the first time in a while and looked in the mirror, but oh my god, why is my complexion so dull? ㅠㅠㅠㅠ I definitely slathered on plenty of nourishing cream last night, too. *sobs*... lol

I don't know if it's because I was too lazy just because it's the weekend, or if the fatigue accumulated over the week is finally showing up on my skin!! lol I'm so curious what face masks or skincare routines you guys use to recharge your energy on weekend mornings!! hehe
