Indentations/crease from compression garment - 3 weeks post-op. (photo)

Thank you for the question! Considering that you had liposuction done fairly recently, I don't believe you have much cause for alarm. Compression garments may cause indentations, but these are usually temporary. Typically, these creases resolve on their own within a few months. 
I'd recommend speaking to your plastic surgeon about possibly changing your compression garment to make sure it fits better and doesn't cause indentations. In addition, you may want to consider massaging the affected areas but get your surgeon's approval first. 
An in-person exam with a board-certified plastic surgeon would be the best way to assess your situation and guarantee an individualized medical advice. Best of luck!  
 

You look swollen and the indentations are likely from the garment. Any specific concerns should be addressed in person with your surgeon. Good luck.
