Good Day. Thank you for you question.Any filler, including Bellafill can be used in these areas. The health professional needs to confirm the goal of treatment.If volume replacement is the goal, then Bellafill is an option. I rarely place filler in the forehead, occasionally along deep horizontal furrows. The temporal fossa is a common anatomical site where I inject. The area between the eyes (glabellar area) and the nose are the facial anatomical areas with the highest risk of blindness due to the filler traveling into blood vessels. This risk I always present to the patient.Minimizing the risk of blindness is by initial injecting lidocaine with epinephrine to allow the blood vessels to shrink in diameter (vasoconstrictor). Next, using a microcannula (25 gauge) in the avascular plane immediately above the cartilage and bone of the nose or the plane immediately above the covering of the bone (periosteum) in the glabellar area with minimal injection pressure after the application of ice for further vasoconstriction.Often skin resurfacing of the forehead by lasers or RF yields an excellent cosmetic improvement compared to attempting volume replacement to the forehead.
