The author provides a clear explanation on the definition and indications of cryolipolysis, reinforcing that it is not a weight loss treatment as it does not shrink fat cells. Some of the popular devices are listed, including CoolSculpting®, Cristal®, as well as Clatuu™ Sculpt Freeze with reference to which technologies have CE marking and Food & Drug Administration (FDA) approval. An outline of fat reduction using cryolipolysis is explored, underpinned by several current studies to support the safe and effective treatment potential. Some statistical data is conveyed outlining the quantity of average fat reduction, which may be expected to reach up to 25% following a single session, though it is not known if the longevity of the treatment varies between individuals; the author reinforces this consideration. A reported variation in the contraindications is briefly described, with indications for treating anatomical areas reported to be relatively consistent between devices. A discussion of side-effects includes rare adverse events such as paradoxical adipose hyperplasia (PAH), which the author states can be under-reported, yet no rationale is provided for this. In addition, the author acknowledges the small number of current studies and limited data on the long-term effects of cryolipolysis treatments.
