Which procedure would help minimize the appearance of horizontal line between my eyes after bridge and forehead filler? (photo)

I encourage you to visit with an expert injector for evaluation. It may improve with Botox if it changes when you animate. You can also consider Morpheus8 treatments which address skin tone and texture.

In order for the contour to be continuous or congruent between the forehead and the nose, adequate fillers must be placed and contoured appropriately and naturally.
Another consideration in addition, may require the use of neuromodulator to weaken the procerus muscle that maybe increasing the crease there.
Please see an expert in Australia, there are many, to "finish" the job appropriately and safely.
Good luck.
