I use this on my under eye area when I have been pulling long shifts at work and it really does make me look less tired and drawn out. I don't find it creases and it stays put all day.
Because it is in a stick form, I like to apply this to my ring finger and then blend it in a downward triangle. The reason I do this is because I am paranoid about the action of applying it on my face creating wrinkles haha.
It is very easy to blend out and melts into my skin with no issues. I do like to set this with ELF's undereye setting powder, as this prolongs the wear even though the wear on this is excellent anyway.
Be warned that the consistency of this tends to be a little heavy, so it is best to use a light hand initially as thick concealer under your eyes can age you.
I like using this product as a blemish concealer, not under eye concealer, found with me it would crease my under eye area a lot. I quite like the simple packaging its easy to apply and control of how much product is used and it lasts such a long time!!
