Deep line on mid cheek. What is it? Please help. (Photo)

A few months ago I developed this deep crease on my right cheek it starts underneath my eye and goes all the way through the middle of my cheek all the way down to my jaw at kind of a weird angle. I'm not sure if it's a deep sleep line or due to the fact my weight tends to fluctuate and I recently lost 20 pounds. If this is due to my weight loss will it even out over time im only 23, or is this something that requires surgery to fix? Thanks for the advice in advance.
