What affects the longevity of dermal filler?

Dermal filler longevity can depend on numerous things. If you have a high metabolic rate, you may metabolise the product more quickly. This is because dermal filler, is a long chain sugar molecule bound to water. People who often have high metabolic rates are “gym junkies”. This is because exercise increases metabolic rate, and, therefore, also cause the product to metabolise more quickly. In saying this, everyone is different. I know many people who exercise regularly and their dermal filler lasts for over 1 year and other people who do not exercise, can metabolise the product more quickly. 
 
Some clinicians also say that smoking impacts longevity of filler, although I’m not aware of any actual studies plublished about this. The only thing is that if you have had filler in the lips, or peri-oral, the muscle contraction of pursing the lips may impact the longevity of the filler. Personally, I have seen many of my patients who smoke, not get the long-lasting effects that someone else has had who doesn’t smoke, but this could be coincidental.
