I used everything in the kit this morning and it's been 10 hours now.
Celebration Illumination Foundation: I applied 2 very light layers because I was worried it would get cakey if I applied too much at once or applied more than two light passes. I set it with WEN Replenishing Treatment Mist. It did not look metallic and did last the day, but I think the Fair is too fair for me and I know the Light is too dark. I wish It Cosmetics would recognize that women come in more than 5 shades and they exclude a LOT of women across the wide spectrum of colors when they only account for 5. I'll try a few more times, but this may not be a good match for me.
Brush: It's not as soft or fluffy as the other It brushes, but it's a duofiber and isn't supposed to be. It's a nice weight and felt good to use. I'm always happy to have a new duofiber brush on hand.
Blush: This blush is a very nice color and looks like a natural flush. The ombre color scheme is matte where the color is most pigmented and has some pearl at the lightest end. I swirled them together and got a lovely color that was not too pink and not shimmery.
Gel Eye Liner: Eyeliners are usually throwaways for me because I don't really like them. They're often too hard or too soft, don't go on easily or don't stay on. This one is perfect! I used it to tightline my upper lashes and it was easier than any other pencil I'd used to tightline and stayed all day. This was the item I expected the least from and the item I'm most impressed by. I'm going to have to get another in a different color - maybe a blue.
Fiber Mascara: I found it a little hard to apply to the outer and inner edges of my lash line because of the ball, but it did go on and wasn't messy. It lasted all day and I've had about 3 flakes in the last few hours. Many mascaras give me smudges under my eyes, but this one has not. I don't know if I would repurchase, but I'm pleased enough to continue using it.
Overall: Disappointed in the match with the Celebration Illumination foundation. I tried it in an Ulta before I bought this kit, but the lighting in there was terrible. I'm happy enough with the rest of the products that I will keep this kit, but I am canceling my Auto-Delivery shipment.
