I keep waking up with eye creases?

For the past week or two, I've been waking up with eye creases under my eyes. It is really starting to annoy me because I feel like they're going to stay permanent. My right eye crease is starting to look more prominent than my left one. I try sleeping on my back, but I am a side sleeper, I can't help it. I've tried changing my pillows, sheets, putting eye cream on at night, nothing works. Should I buy the ROC correction eye cream? I'm 27 by the way. Do those creams make it worse or make you look older? I dunno what to do, I would love to keep my youthful appearance for as long as possible. :)
