Effect of bellafill injections disappeared 5 days after injection.

It is normal for the initial appearance after a Bellafill treatment to go away after a short period of time.  The collagen that delivers the Bellafill product gets quickly absorbed and will cause the appearance to go back to normal.  It then takes several weeks for the Bellafill to stimulate the tissues to produce gradual filling over time.  Most people require more than one treatment session to obtain the desired result.  I usually wait about 6-8 weeks between treatments.    

Bellafill has become an excellent alternative to implants for chin augmentation. With less significant side effects and ease of use it may very well be the procedure of choice.Suneva the distributor of Bellafill shows results lasting up to five years.  PMMA microspheres compose twenty percent and collagen eighty percent of Bellafill.  The microshperes do not reabsorb or decompose; the amount of collagen produced surrounding the PMMA changes with time and age.
Results vary from patient to patient.  Several injections sessions are typically required to produce the desired end result. Bellafill is only FDA approved for injection in the naso-labial folds and acne. Other applications are considered off label use.
Most patients elect to have a less permanent filler injected for the first time to see what can be done. Afterwards they often choose Bellafill to give longer lasting results.
