Under eye bags/dark circles

I had polynucleotides injected a week and a half ago but don’t see any improvement (the doctor said I should be able to see some results after a week). I have two more injections scheduled and I’m wondering if it would be better to cancel and spend my money on a different treatment. As far as I can tell there is a very slight bulging of the fat beneath my eyes but nothing significant. I assume the main issue that I should try to treat is the discoloration and skin texture.
