Ways to remedy a very defined labiomental crease--without botox? (that's the crease underneath the bottom lip, above the chin).?

So, I'm really self-conscious about this. I'm only 22, but I have a full fledged, and very noticeable labiomental crease. Although everyone has the crease to some degree, mine has taken on an appearance that is way more distinct and noticeable.

People aren't usually supposed to see its definition until their later years, but mine came about now because of a sinus infection (bear with me for a second, I'll explain). So, this Fall I had a horrible sinus infection that left my ears extremely clogged. I constantly tried "unclogging them" by doing that jaw shift thing--you know the one, people do it to unpop their ears on airplanes. Well, the clogging was so bad that it lasted for a while and so I kept doing the jaw shift thing. The jaw shift maneuver--I don't know its actual name--is likely why I've seen an increase in definition--the labiomental crease is apparently made more noticeable by "continuous upwards shifting of the bottom jaw." Anyway, now my chin has somewhat of a parabola shape above it, and it's making me extremely self-conscious.

My question is: has anyone experienced any similar definition developments in this area before? If so what did you do about it, or what would you recommend?

To the general public: what would you recommend to remedy this? Do you know any affordable ways that aren't botox? Maybe a brand of wrinkle cream of some sort. Thanks!
