The product of liposuction is fat. As the fat comes from your own body there are no allergy or intolerance problems associated with injecting it into another part of the body such as the lips or breast.
WHAT TO EXPECT
Following liposuction the fat is processed and turned into a liquid formulae. It is then injected into the receptor site. As the fat will slowly be reabsorbed into the body,more is usually injected than you think is necessary.
It is an excellent filler than can be used anywhere on the body. It is particularly useful in breast reconstruction following a mastectomy or partial mastectomy.
You need to have the liposuction to harvest the fat cells. More than is required is injected initially as the fat does get reabsorbed into the body. This can lead to a swollen or over-filled look, particularly on the lips.
