Under eye colour change

Hi all new to the forum, seen posts about this already so apologies for beating a dead horse,

Male, 28 been on Roaccutane for 8ish months 40mg a day, so far so good only main side effect is the usual dry lips.

However past few weeks noticed under my eyes are almost purple/look bruised, read it's a common them due to thinning of skin etc. kinda worried as I've seen posts about this not going away after the course is finished what is everyone's experience? only got 2months left so feel it's pointless stopping now, but really don't wanna be left with this

Some people say use vitamin C serum then half say don't use due to irritation? (Will speak to my dermo also)

Thanks Tom
