Hey,
Well to be honest you can't really get rid off the puffiness under the eyes.(There are some things you could do to reduce it for example placing cucumber on it or put something cold on it...)But the only thing which would work in the long term is surgery. The best thing you could do is ask a specialist.
However if you want to cover up the darkness you can easily hide it by using color corrector concealer 😄
I have done a few videos about it also live streams where I am showing you step by step how you can cover it up it isn't difficult if you are using the right colors ♥️
