Your experience is very common following traditional liposuction. Most patients who have had liposuction are very happy with the fat removal and the improvement in body contour. However, as many as 20% of people who have had a successful liposuction report skin irregularities, lumps, bumps, and uneven areas called contour deformities and loose skin.
First, I would recommend massaging the skin and the areas that are swollen or lumpy-this will help. Also, exercising to firm and bulk the muscles beneath the skin can help fill and firm your skin.You are only 12 weeks, you still have swelling, and you will improve with time. You will not know your final appearance for at least 6 months to a year.
When fat is removed from beneath the skin by suction, the skin must shrink or tighten back to the body contour. With large volume liposuction and with patients who do not have good skin tone, often the skin does not shrink enough and loose skin is left behind.
Irregularities and uneven areas occur because of uneven or non-uniform fat removal during the suction procedure.
New laser liposuction techniques have radically changed the occurrance of these problems in my clinical experience.
In laser liposuction, a small laser fiber is inserted beneath the skin to liquefy the fat before it is removed by suction. Melting the fat makes removal much easier, and smaller cannulas (the tubes that suck the fat out) are used. The heat from the laser also tightens the skin as the treatment is done.
In my experience with laser liposuction, in over a year, so far my patients have had uniformly smooth skin and firm skin after their laser liposuction procedure. See before and after photo.
In addition I have had success in correcting skin irregularities in patients who have lumps, bumps and contour deformities after old style liposuction.
The laser fiber is re-inserted and the irregular areas are treated with the laser. Thus treatment has had a smoothing and firming effect on the areas treated. See photo below. On the left I have marked with a purple circle irregularities on the abdominal skin which were left behind after a standard liposuction done two years before.

Laser liposuction is new and not widely available yet. However I am sure the popularity of this technique will rapidy increase because of the smoothing and skin tigfhtening benefits.
As I said in the beginning, you will get better. I would not think about any revision until at least a year after your original liposuction, and by then you may not need it.
