Bellafill® is the first FDA-approved injectable dermal filler that offers a new level of filler rejuvenation for the correction of nasolabial folds and claims to last safely for five years. Bellafill is a non-reversible dermal filler, unlike many other dermal fillers that are absorbed and require reinjection. Bellaﬁll® is different, studies show It restores rather than just fill for natural enduring results. Bellafill is comprised of 80% microsphere 20% enhanced bovine collagen with the local anesthetic lidocaine. The purified collagen immediately adds volume to smooth away facial wrinkles, and the PMMA microspheres help your skin re-create its own firmer structure for beautiful, younger-looking skin and lasting results. All new patients must take an allergy test on an arm one month in advance of injection.
