What about the lipozap procedure? Are they effective at all?

Nope. Lipozap is a combination of velashape and mesotherapy injections. It's not a replacement for liposuction. It's not fda-approved (the meso part), has minimal effect, and is a waste of your money. Don't get suckered.
Lipozap. This product or service can be extremely expensive, and frankly speaking, phosphatidylserine has no actual proven weight loss ingredients. This means that lipozap would just be a waste of time in its proven benefits. It is used in medical spas, and it has not really been proven to do much of anything.
