What methods do you recommend to make a before and after comparison?

Recently I have gotten different fillers applied on my face, and it’s hard for me to know exactly what worked and what did not, and also when exactly the fillers go away. I have tried to take before and after photos and there always seem to be different elements that interfere in me seem differeces, such as lightning, angles, posing... I try to do everything the same way but it is still difficult. Is there an effective way? Maybe 3D modeling?
