My flanks are uneven after lipo. Will they even out?

It is too early to evaluate. Swelling is still very present after one week. It is too soon to worry about the appearance. Wait until the swelling goes down and then evaluate. Your surgeon will help you know when that is. If there is residual fat, more can always be removed. Don't drive yourself crazy after one week. There is a lot of change still to come.

I typically tell my
patients that they will start seeing results 4-6 weeks post surgery. After two
weeks, you are likely still swollen. You can also start massaging the areas
treated to help any residual swelling. Small circular motions to start and
massage deeper if it you don't have any discomfort.

Did you have an asymmetry before surgery? More loose skin on the left side? Those are things to look back at your pre op pictures and think about. That being said, anything you see at 1 week after a liposuction case is going to change as you are still going to be quite swollen. Let your doctor examine you at your next follow up, he or she will be able to best advise you.

After your Smartlipo
procedure you may feel as though your flanks are uneven but you are still
swollen. This swelling will eventually go away, wear your compression garment
to help with any swelling that may occur. As this goes away you will notice a
contour in your flanks. If at 6 months you still feel uneven follow up with
your surgeon for a possible touch up procedure.

At just one week post Smart lipo, it is not unusual to feel that the areas of liposuction may seem uneven.  You are still swollen and may have some bruising which will resolve over the next several weeks.  Be certain to wear your compression garment and make sure to straighten it if it becomes kinked.  Also, using a moisturizer and and doing some gentle massaging will help resolve the swelling and smooth the contour.  Best wishes.
