Went Smooth but the Results Are Not What I Expected...

Im 28 and the dark circles under my eyes have bothered me for at least 6 years now. after a lot of research on on line i have discovered that the problem is actually the hollowness under my eyes. so iv e decided to go to a consultation with a very popular doctor in california. he said that i have just a little bit of hollowness and i would benefit from restylane under my eyes and radisse to give a little bit of volume to my cheeks. i decided to go ahead and do it i was seek of the under eye concealer ceremony every morning!!! he injected a half of syringe of restylane to each eye and a half of syringe of radisse to my cheeks. i have to admit that the procedure was painless and thank god i had absolutely no bruising . at first the results looked amazing i was really happy but after 2 days i have noticed a difference between the eyes. so i went back for a correction again painless and no bruising and once again i was happy with the results but a week after i started to notice my circles again and after a month i looked like i didn't have anything done... the doctor told me that restylane usually lasts for about a year for the under eye area i wasn't expecting a year but a month??? is that possible... maybe he didn't inject deep enough? but he looked so professional and iv e heard really good things about him so im not sure what to think also a bluish color under my eyes which wasn't bad but it just looks like i didn't have anything done... it has been 5 months since than...
