Thank you for your question. It is very important that you seek a board certified plastic surgeon who has expert training with this specific filler. They must be knowledgeable in the anatomy of the face. With this being said, Bellafill is a long term filler giving predictable results when injected with precision and discipline. I identify the anatomy of the blood vessels with the AccuVein device. This is extremely important in the periorbital area and the nasal region. In these areas, I often use a sterile blunt cannula and retrograde injection technique to avoid injecting into vessels. Augmenting the cheeks is relatively easy by placing Bellafill deep using the syringe needle technique. Often overlooked, a very simple principle for patients and surgeons to follow is a facial decontamination protocol before injection. We have our patients remove all makeup and sterilize the face with Baby Phisoderm and generous alcohol wipe preparation just prior to injection to avoid infection and granulomas.Best wishes in your endeavors.
