We wait 8 weeks to retreat in my practice. Sometimes people don't need a second treatment at all. You can treat different areas through.
You have asked in excellent question. There is no absolute right or wrong and each situation must be handled individually. If you question the judgment of the person you have been seeing for treatment than I would suggest obtaining another opinion. Best of luck.
We usually wait between 2-3 months before doing the next CoolSculpting treatment. Though results can be seen in as little as 3 weeks, it can take up to 3 months for maximum results from a single treatment. I don't see much point in killing fat cells that are already dead so we don't treat sooner than 2 months.
One of the major benefits of having an additional procedure so shortly after the first is because you'll end up seeing a great amount of reduction in the area throughout the three months that your body is ridding itself of the dead fat cells. It's perfectly acceptable to wait between treatments however there are benefits in having them closer together, it's really up to the patient's discretion.
There are many physicians who repeat the procedure 4 weeks after the initial procedure. I prefer to wait to see the results before re-treating the same area. Best, Dr. Green
I usually have my patients wait 8 weeks. If they are treating in a slightly different area (Say just above or below the initial treatment) I will do it right away. That said there isn't any harm in retreating at 4 weeks, I just like the body to clear out the dead fat cells. There's no point in retreating them! Good luck, Dr. M
