I patch tested Bellafill 10 days ago and no allergic reaction. Should I wait 3 more weeks?

Hi, and thanks for your question. I have been injecting Bellafill (previously known as Artefill) for 8 years. I have injected thousands of patients and have seen a mild reaction maybe once. In Canada, allergy testing is often not done at all because reactions are so rare. For these reasons I mostly do an allergy test on the day of injection, wait about 30 minutes and, if there is no reaction, proceed to injection right away. My opinion is that if you are not seeing anything at this point it is safe to proceed. Of course there is no harm in waiting 3 more weeks, but I think it is not necessary. Hope that helps. 

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.

Best wishes,

the package insert says to wait 30 days.  I find that if you are clear after 72 hours there is likely not going to be a reaction.  Best, Dr. Emer.

Best to wait the full 30 days from the date of the skin test if your going to do it the right way. Just be aware that a negative skin test does not guarantee that you wont have a reaction to Bellafill when more of this filler is injected into your face. With that being said, in having performed over 2000 syringes, I have not yet seen a positive allergic reaction to Bellafill so a positive skin test would be very rare. In fact, the skin test tests for hypersensitivity to the bovine collagen component of Bellafill, not the Bellafill PMMA crystal.

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!:)
