Being out on the town with your friends, mixing it up, enjoying the company, the music, the lights. Or perhaps you weren't having such a great time. Maybe the baby was up most of the night with a cough and fever and just couldn't be consoled.
Whatever your reasoning, it all boils down to you didn't sleep very well last night and the effects are showing. You have that groggy, heavy-headed, feet-dragging, day-is-never-going-to-end feeling.
You may be able to guzzle down enough coffee and energy drinks and work in just enough jumping jacks to keep yourself plugging along until it's finally time to call it a day, but what's happening on your skin is a different story. How can you perk your face up again?
