I used the LP serum for a while, in a long term, it does help firming your under eye, and brighthen eye area which is not obvious in my face, cuz I don't have dark circle.
The amazing thing I did is that I put Fresh rose mask under eye, and it is very very helpful. I checked the mask and find it has cucumber which is definitly helpful for de-puff. So it worth trying. And I also used the SPA science eye patch (from drug store), and it is so far so good, and cheap ~~~
Bliss baggage handler is also good for morning time, diminish your puffness.
Other eye creams might be good, but not for puffness I will say. LP used to have 2 other eye cream, but they are discontinued....
