Suggest Treatment For Dark Circles Under The Eyes

Question : Hi there, when I was in my late teens (I'm now 27) I went on Roaccutane for a few months and not even really a heavy dosage amounts either. Since then I've had darker than normal circles underneath my eyes. To attempt to make things better I used my mum's hydrocortisone cream under my eyes quite a few times before I found out it thins the skin.. and I stopped. It hasn't ever REALLY been an issue until recently when unfortunately I went through a stage of heavy drinking every night before bed, just to get sleep - due to issues in my life. I noticed the dark circles get much worse as I've been doing this for over a month recently. To counter this, I bought an anti-aging eye cream that specifically addressed dark circles, the cream is coloured and not plain white. That helped (and I know this will sound silly) but only when I used it.. the cream unfortunately was kept in my car on some very hot days after which I used it where I'm not sure if it was affected or not... but now I've come to a point where I've quit smoking (I'm on my fourth day).. I'm sober, I'm no longer binge drinking and I want to be healthy again. However, and I'm not sure if this requires just time, but the dark circles even with constant water drinking and after a shower, look like I've been taking drugs... in certain light, the skin is almost reflective and makes it look like pre-work for Halloween! I've started to use Bio-oil underneath my eyes at night but I would like to know is there anything I should be doing to help return the skin to normal colour? Thank you
