Dior Addict in Urban 178 is a Sephora exclusive. It's a pale frosted pink with a sheer glossy finish. The texture is very moisturizing. About 6 hours after it has faded, my lips feel soft and smooth (bonus!). Being a lighter shade, I found the pigment to be on the sheer side. Compared to the Chanel Rouge Coco Shine in Boy, it has a similar natural finish but harder texture which I think helps the color show better. The new Dior Addicts apply better than the recently discontinued Addict High Shines which I found a bit tacky in texture. The new formula is smoother with a high shine finish. Being a lip-balm like lipstick, lasting power isn't the best. I'll have to test the brighter shades to see how they wear. So far thumbs up for an easy fool-proof type of lipstick if you don't mind re-applying. As an added bonus for those sensitive to fragranced products - no detectable taste or scent with these lipsticks.
When trying Dior Urban 178 out at Sephora on my hand, I thought it would have been too pale for my skintone. I would have gone with a slightly brighter neutral pink like Basic 253. This particular shade was sent to me by Dior and surprisingly, it's not too pale that it washes me out. The sheerness helps make this color more wearable. I suspect wearing a lipliner blended out on the lip first will help the color last longer. If I were just the slightest bit darker than I am right now (about a Chanel Vitalumiere Aqua in 20 which equals a MAC NC30) I think this color would have been too pale by itself.
Compared to a few other pale pink shimmers: Dior Addict Urban, Chanel Rouge Coco Rose Comete, MAC Lipglass Oyster Girl, MAC Lustre Lipstick in Politely Pink
All have that sheer shimmery glossy texture:
