Liposuction and lipoinjection for contour correction currently rank first among aesthetic procedures performed worldwide. The frequent use of these procedures has led to rapid advancements, innovations, and the introduction of numerous new methods and tools in recent times.

The first question that comes to mind is whether there is an increase or decrease in the number of fat cells throughout a person's lifetime.

This question also relates to the permanence of liposuction procedures because if the body can generate new cells at any time, surgically removing excess fat tissue becomes meaningless.

In the first year after birth, the number and volume of fat cells increase by an average of threefold. The growth and increase in the number of fat cells continue until the age of 5. After puberty, the number of fat cells stabilizes. It is assumed that this number is genetically determined and is unique to each individual, unaffected by environmental factors.
