- Cosmetic Agent, Implant
After implantation, the bovine collagen component dissipates over the course of 1 to 3 months, leaving behind the nonbiodegradable PMMA microspheres. The microspheres stimulate a local inflammatory reaction that is followed by the deposition of granulation tissue during the first few weeks after implantation. The connective tissue subsequently matures, and by three months after injection, PMMA microspheres are surrounded by newly formed collagen. The presence of new collagen accounts for the observed volume-filling effect (Cohen 2004; Lemperle 2010).
Use: Labeled Indications
Nasolabial folds and facial acne scars: Correction of nasolabial folds and moderate to severe, atrophic, distensible facial acne scars on the cheek in patients 21 years and older.
Hypersensitivity to polymethylmethacrylate, lidocaine, bovine collagen, or any component of the formulation; positive response to Bellafill Skin test; patients with severe allergies manifested by a history of anaphylaxis or history or presence of multiple severe allergies; patients undergoing or planning to undergo desensitization injections to meat products; patients with bleeding disorders; patients with susceptibility to keloid formation or hypertrophic scarring; use for lip augmentation and injection into the vermilion or the wet mucosa of the lip.
Note: A skin test should be performed 4 weeks prior to treatment. Refer to the manufacturer's instructions for use for additional information on the interpretation of skin test results.
Nasolabial folds and facial acne scars: Intradermal: ≥21 years: Inject as needed for cosmetic result; injecting >3.5 mL per treatment site or 8.9 mL overall has not been established. Correction should be limited to no more than 100% of the skin defect during treatment. One or two touch-up implantations at intervals of at least 2 weeks may be required to achieve the desired effect.
Refer to adult dosing.
Bring syringe to room temperature before injection. Injection area should be washed with soap and water then cleaned with alcohol or other antiseptic. Refer to manufacturer's instructions for use for comprehensive administration information.
Store in refrigerator. Do not freeze.
There are no known significant interactions.

Concerns related to adverse effects:
• Intravascular injection: Inadvertent intravascular injection of dermal fillers may cause embolization, vessel occlusion, ischemia, or infarction resulting in vision impairment or blindness, cerebral hemorrhage or ischemia, skin necrosis, and damage to underlying facial structures. Treatment should be discontinued and patient promptly evaluated if exhibiting any signs or symptoms of intravascular injection.
• Skin effects: Hyperpigmentation, keloid formation, or hypertrophic scars may occur after dermal filler injections.
• Acne scars: Safety and effectiveness have not been established in patients with non-distensible atrophic acne scars, ice pick scars, or sinus tract scars.
• Connective tissue disorder: Safety has not been established in patients with connective tissue disorder.
Concurrent drug therapy issues:
• Anticoagulant/antiplatelet agents: Use within 3 weeks after administration has not been studied.
• Immunosuppressive therapy: Concomitant use with immunosuppressive therapy has not been established.
• Other dermal response procedures: Laser treatment, chemical peeling, or similar procedures may elicit an inflammatory response at injection site.
• Other wrinkle therapies: Use within 6 months of other wrinkle therapies (eg, collagen, botulinum toxin) has not been studied.
• Cold weather: Exposure to extreme cold weather should be minimized until initial swelling and redness have resolved.
• Photosensitivity: Excessive exposure to sun or UV lamp should be minimized until initial swelling and redness have resolved.
• Skin inflammation or infection: Treatment should be deferred if active inflammation (eg, cysts, pimples, rash, hives) or infection present at injection site(s).
• Skin testing: Skin testing must be performed; patients with a positive test, two equivocal tests, or demonstrating an anti-bovine collagen serum IgG level outside the normal range at baseline should not be treated.
Women of reproductive potential not using effective contraception were excluded from initial studies (Cohen 2004; Joseph 2015).
Pregnant women were excluded from initial studies (Cohen 2004; Joseph 2015).
