Will Radiesse Dissolve Faster if the Area is Massaged Frequently?

Neatest trick I have learned to get rid of Radiesse bumps or lumps that might develop. Get yourself one of these vibrating toothbrushes. Have it massage the area where the bump is for a 5 minutes every few hours a day, especially when bored and watching TV. Within a few weeks the bump will get significantly smaller. It's a great trick especially with a material like Radiesse for which no "antidote" can dissolve it and which can solidify due to its calcium content and produce some quite noticeable and even painful bumps.

Massage will help break down lumps that has formed.  However, it will not break down the actual radiesse or allow your body to assimilate it any faster.

Most products will break down faster under mechanical manipulation. Therefore, frequent gentle massage should theoretically reduce the longevity of the Radiesse.

The effect will dissipate over time and massage will not affect the molecular degeneration and absorption of the product. You will need some patience and perhaps a consultation with a good cosmetologist on tips to camouflage the area with which you are not pleased.

Rubbing or massaging Radiesse will not help it dissolve more quickly. It is best to just leave it alone and let it dissipate on its own. It may take 9 months or so before you start to notice that it is going away. In some areas it will last up to 2 years, but with most fillers, they do not last as long in the lip due to constant movement.
Other fillers may be able to help camouflage the ridge or line that you are seeing.
And, for anyone else that might be reading this... do not use radiesse in the lips!

I have never injected Radiesse in the lip area and I am sorry that you have had this result and found out after the fact that it is not recommended for this region. I would recommend Juvederm or Restylane as the only fillers for this region. With this said I will tell
you that time will help
the Radiesse dissipate. I
would just leave it alone
and you should see some improvement within the next six months to a year. I wish I had a better answer for But rest assured time is on your side!
