Is there anything that can be done to even out the uneven creasing under my butt? (Photo)

In order to correct deformity of infragluteal crease, a combination of liposuction and pplacement of deep sutures may be required. This can be combined with a true buttock lift, if needed. Good luck.

Thanks so much for reaching out. Actually, that area is very difficult to treat. Using liposuction is always dangerous for losing support. You may consider a noninvasive device like emsculpt however, I would have a limited hope that it would address your concerns. I hope this helps :-)
