This stuff is amazing. I honestly can't get over how perfect it is for me - and I've been on the quest for a HG undereye concealer for what feels like forever (okay, probably only a couple of years, but still).
Why so much love for this? Well, it not only has amazing coverage, it also:
-doesn't oxidise on my fair skin (I use NC15, which is a perfect match).
-contains no glitter or sparkle like heaps of other concealers I've tried.
-sets to a super natural demi-matte finish.
-blends super well so that it's easy to get away with wearing just a bit of concealer under the eyes without it being obvious that I'm wearing makeup.
-covers redness and blemishes well also (although I personally am loving the Collection Lasting Perfection concealer for that purpose at the moment).
-and last but not least.... DOESN'T CREASE. That's right. It doesn't crease. I still can't believe it. Even without using powder to set it, it *still* doesn't crease. Obviously I can't guarantee that it won't do that on everybody, but on me personally I have had no problems.
Now, I will repurchase this forever (unless my dark circles disappear - now that would be awesome!), but there are a few things to be aware of:
-Unfortunately, as everybody else has already said, the pump is terrible. It is really hard to control, no matter how careful you are, and so it's very easy to end up with way too much pumping out. I ended up buying a tiny screw-top container and now I just put one pump in there and use it all up (usually it lasts me for about three days) before I do another pump. It's a bit of a pain, but worth it for the product.
-This is relatively pricey, at $40. However, I can justify it because a) it's by far the best concealer I've found, b) it lasts forever - I've had mine for about four months, and I've used maybe one sixth of the product inside, and c) most "drugstore" concealers are nearish $30 anyway - I'm looking at you, Revlon! Overall, I'm willing to pay it.
Phew, this was a long review! As you can probably tell, I'm rather passionate about this product. Hope that helped some of you! If in doubt, try and go in to a counter and ask them to colour-match you/try it on before you decide. :)
I really like this concealer, it has nice coverage, easily blendable, and doesn't crease on me. I brought this in NC20 and NC25 direct from MAC US (much cheaper!) I like NC20 for a highlight concealer under my eyes and the NC25 for on spots etc. the main problem I have us the packaging though (like everyone says!) it's pump is horrendous!
Tips: The pump is terrible and pumps too much out, so I have a little container that I pump the product into so as not to waste it, any excess is sealed up for next time.
