When Will I See Results from SmartLipo Treatments?

At one week the amount of swelling is almost as much as the amount removed.  But by two weeks, the swelling should really start to subside, and by a month patients will usually see a big difference.  But hold judgement for at least three months, as swelling will not resolve for at least that long.

Smart lipo, just like regular lipo takes time to see full results. I usually warn patients that initially they may even look bigger right after a procedure due to the tumescent fluid and swelling. Usually by 2 weeks they can tell that they are smaller but I warn them they are far from maximal or ideal.

You're not seeing results after SmartLipo because swelling from the procedure is obscuring the improvement.  This swelling goes away at a different rate in everybody, but in general, I see that most patients will see about 80% of their final result after 8 weeks.  It can take up to 6 months to see the true final result.  

After any liposuction procedure there is a time period (usually a few weeks) when you will have swelling.  This swelling will go away.  As for your specific case, 300 cc is a good amount for a thin person but a drop in the bucket for a larger person.  So, without pictures, it is difficult to comment specifically on your case.  Good Luck.
