What happens if a filler like Bellafill were to melt after a procedure like a full radio frequency needling procedure?

Thank you for the question. As others have pointed out, the placement of the Bellafill will make it very unlikely that the product would be affected by the heat from an RF treatment (e.g., Infini). Bellafill is placed deep in the skin, while the Infini treatment is generally in the area of 2.5 to 1mm in depth. In my practice, I use a combination of Infini and Bellafill for acne scarring. Generally I do the Infini first, with three to five sessions about six to eight weeks apart. Then I do Bellafill for any residual contour issues. This combination works great.

As others have said, Bellafill is placed deep below the skin.  Even if RF energy were to heat the PMMA molecules, most experience has shown us that this only amplifies the collagen building effect and will not damage the results.

I do Bellafill with lasers/RF treatments all the time. The RF machines/lasers won't melt Bellafill and they work well together in combination. Please see an expert.  Best, Dr. Emer.
