The results of a fat transfer look natural and can last for a long time with proper care. Dr. Katzen uses the latest techniques to purify and graft fat, as well as minimize reabsorption. Despite this, there is usually still a small amount of fat that does not appropriately stick to its new location so Dr. Katzen typically adds slightly more fat than is needed. If you want to enhance or touch up your results after a few years, a second fat transfer may be performed.
