This is good for concealing undereye circles and evening skintone. It's not good for acne scaring or cover. I wear it for about 8 hours and I notice no creasing under the eye. It's very blendable, and quick to apply, but once agin not good for acne. 

I have usually had success with Neutrogrena products.  They work great for sensitive skin.  I applied this in the morning under my eyes and just an hour later noticed visable creasing.  Not good for my 41 year old eyes.  I also believe it wore off too soon, but that could be attributed to living in a high heat and humidity area. 

I bought this concealor for the dark circles under my eyes, since the package said it was a creamy consistency perfect for the delicate undereye skin.  I like the packaging and the concealor has a very soft, creamy texture (in fact it's so soft it almost borders on greasy); however, it is so sheer that it hardly covers my undereye circles at all.  It does seem to have a little bit of light-reflecting particles in it; when the light is at the perfect angle it does reflect the light and you can't see the dark circles.  However, the vast majority of the time the lighting is not at that perfect angle and you can see my circles. :(  Maybe you could mix with this another concealor and it would work better, but I would recommend not buying it.
