I own a lot of Mac products, I have a huge collection of makeup and I'd say that 75 percent is Mac... Unfortunately I can not give their eye shadows a high rating. As many others have stated the pigment is just not that great. I have seven Mac eye shadows that I purchased all around the same time. I have Sweet Lust, Nehru, Mystery, Divine Decadence, Lucky Green, Honesty, and Gilty Morsel. I also have an old Sunset B one that's been discontinued. Now here's where I go into a long drawn out description of the pros and cons of each, so scroll on if you don't want that.
First is Sweet Lust. I bought this one online and it looked like such a pretty light pink. When it arrived it was a little lighter than expected but that didn't effect my review of it because we all know sometimes things aren't the same on the internet as they are in real life. It is a beautiful color in the pan... Unfortunately that does not transfer to skin. on skin it's almost white. It would work wonderfully as an under brow highlighter but not a pigmented lid shadow. This was very disappointing. BTW I do use primer so that is not the issue.
Nehru... This was probably the most disappointing. I bought this one in the store, it looked great in the display case and I even liked it when it was on. I wore it constantly, but here's the part that I want to tell everyone out there buying the stuff online. It's not blue, not even remotely. It is black. I didn't even know it was supposed to be blue until I went online and looked it up. That annoyed me to no end, because they are misrepresenting this product to online shoppers. If you are looking for a nice dark blue look elsewhere. Other than that it is a nice black if you want that and it does blend well and is pigmented nicely. (a side note, this might look blue on a different skin tone I am a NC15)
Mystery this appeared Matte on the website but it's not there is a little bit of glitter in it which isn't a huge deal but if you're looking for specifically matte shadows this would bother you. It is pigmented nicely it will take probably 3-4 coats without primer to get the same color as what's in the pan which isn't that great to me. If that doesn't bother you, then go for it!
Divine Decadence is a nice silky color. I would actually recommend this color. It was the first color I ever got from Mac. If you like a nice silky bronze-brown color this is for you!
Lucky Green. I actually really like this color it is just as it looks on the site, it is not as pigmented as I would like it takes about 3-4 coats without primer, 2-3 with it to get the color in the pan. the finish is nice, overall it's a pretty nice color.
Gilty Morsel this color was a huge let down. I bought it online and it looked to be a light green, it's not. It's a goldish color in pan and appears a little shimmery and slightly yellow on skin. It's okay for a highlight and even to blend out Lucky green but it's not a nice all over color. I'm not sure if this color is discontinued or not since I didn't see it above.
Honesty. This color is okay. I got it to go with divine decadence and the two look good together. It's not very pigmented at all and it's not very buildable. after a good bit of work with this color it will eventually look like a tan glittery color but it's not what I expect out of a high end, relatively expensive shadow.
I won't go into detail on Sunset B since it is discontinued but the pigment is bad and it's not one I hardly ever use.
Also something that should be mentioned with all of these shadows is that they disappear quickly. After 3-4 hours you can't see them anymore, not even with primer. the fallout is pretty bad too especially the glittery colors. You wind up looking like you put glitter all over your face, which I don't like. One good thing I have to say about them is they do seem to be crease resistant which is good, but so are a lot of other shadows on the market... I would not recommend these eye shadows which kills me because I love Mac so much and other than this I have nothing but good things to say about them...
I would suggest if you like the colors and are willing to work with it maybe getting the pigments, I've had much better luck with those, obviously the pigments are a little harder to work with, and the fall out at first will be bad, but after you learn to use them you get much better color payoff and they last a lot longer on the skin! Not to mention how long you can use them because it only takes a very little bit with them so you get 100x the life of average shadows! Hope this helps someone!
