Does everyone have a guaranteed and successful result?

In medicine there is no such thing as a guarantee. In fact there is no treatment in any corner of medicine that is guaranteed to work on absolutely everyone. This is because we are all different and our bodies and constitutions are of course also different. Indeed our fatty compositions can differ with some patients having a higher proportion of more “grisly” or fibrous fat than others. This could affect how the fat responds to cooling. Unfortunately it is not possible to know ones composition of fat without actually sampling this by way of a more invasive procedure such as a biopsy. As a result there will always be a small proportion of people who may not respond to fat cooling as anticipated. This is probably of the magnitude of about 1 or 2 in 10 people.
