Nars Radiance Concealer Dupe?

[AbstractDot]

Can anyone recommend one? I've just ordered on and it's too dark, reluctant to order another and get the shade wrong but now realising that I should be checking for dupes first anyway!

I really like Benefit Boi-ing cakeless concealer. Not that much cheaper but it does wonders for my under eyes.

No7 Hydraluminous under eye concealer is super lovely as well. Not as much coverage but very brightening.

Collection concealer was supposed to be a dupe for NARS I believe. Don't know if that's true but it's bloody good.

Where did you order it from? Some retailers may accept a return/exchange, no harm in asking

Also what does dupe mean? If less expensive, then no idea. Same/more expensive would be Laura mercier (slightly less coverage but nicer finish) I use them interchangeably.
