How long does it last? Filler half-life

* Individual results will vary from patient to patient.

Hyaluronic acid-based fillers have a half-life (the point where we estimate the half will be gone), of 15-24 months, depending on:

• The brand of the filler. Generally, the more expensive the filler is, the longer it will last and the firmer it feels.
  • Juvederm Volux and Teosyal Ultra Deep have the longest estimated half-life of all the fillers we provide.

• The patient’s metabolic rate (related somewhat to their age and fitness level).
  • The filler will generally last a little longer in a 40-year-old patient than in an 18-year-old patient.

• Lifestyle and individual factors.
  • Some people metabolise Hyaluronic filler faster than others, for unknown reasons.

Reabsorption Profile

Hyaluronic acid fillers are metabolised (reabsorb) at a roughly even rate each month (2 – 7% p.m., depending on the brand).

The durability quoted is a half-life, meaning the point at which it is estimated that 50% of the filler will remain.

Ellansé is a higher-risk filler based on a polymer (plastic-like) substance. It lasts longer than Hyaluronic acid; however, it is not as safe.

Ellansé

Ellansé is broken down by the body in a different way than Hyaluronic acid.

Almost all of the effects of Ellansé are present up until the estimated end-of-life of the product.

Once the active ingredient Polycaprolactone degrades (~4 years), nothing remains to stimulate type III collagen, and the results quickly fade within 6-12 months.

Body fat as a filler. Fat surgically transferred to the penis generally lasts around 12 months before the body reabsorbs most of it.

A small amount of fat may survive for several years where fat has successfully vascularised (gained a blood supply) in sections along the penis.

The penis does not naturally contain fat, making the survival of transferred fat less likely than in other areas of the body such as the buttocks, breasts, and face.

Fat Reabsorption Profile

Any transferred fat which has not attained a viable blood supply within a matter of days will be either passed out of the body or form hard calcified nodules of necrotic fat. Successfully transferred fat and calcified necrotic fat nodules may survive for a number of years in the penis.
