Thank you for your question. You should ask your doctor the timeframe for the timeframe for which they are most comfortable. The fact that the injection site is imperceptible is great news, and many surgeons move forward after an allergy test in different timeframes. Always consul with a board certified facial plastic surgeon.
Bellafill filler injectable is FDA approved for the correction of facial wrinkles known as nasolabial folds or smile lines, and the correction of acne scars. Bellafill works and keeps on working! Bellafill is a bio stimulant facial filler that works with your body to start producing your own body's collagen in the desired injected areas. Everyone's body is different and may react in different ways to certain things so doing the skin test 10 days before your injectable appointment is a great idea! It will reduce the risks of any allergic reaction! I hope this helps you on your journey!:)

Thanks for your question. Bellafill contains bovine derived collagen and thus could provoke an allergic reaction in a patient who has allergy to red meat. Back in 2009 there were cases reported of a delayed anaphylactic reaction to red meat. In the southeastern/central US (Virgina, North Carolina, Arkasas, Oklahoma, Missouri) it is believed that antibodies formed after a bite from the Lone Star tick led to a subsequent allergic reaction to red meat. Overall in the US population this allergy is quite rare. Persons with allergy to bovine collagen will have reactions as well to eating red meat especially if it is a fatty red meat (they might get away with eating a small amount of lean meat without a reaction). In other countries the Bellafill skin test is thus "optional". In the US it is done but many practitioners skip it or don't wait the 28 days if the patient clearly has no reaction reported to red meat by history. The Bellafill skin test also tests for allergy to lidocaine, but most people opting for Bellafill injection have already been injected with other fillers which contain lidocaine and there is no prior skin testing required before injection of these other fillers. In my practice we have started testing many of our clients who get dermal fillers on some sort of regular basis, even if they are not there for Bellafill that day. Thus, if they decide to switch over to Bellafill at a future time there is no "extra waiting period" for a skin test result almost sure to be negative...Interestingly, Abobotulinumtoxin A (Dysport) is contraindicated in patients with cow's milk protein allergy because bovine protein is a constituent, yet there is no skin test required prior to its injection.Best,Lisa Vuich, MD
