The new liquid eyeliner from Dior, Dior Addict It-Line, is somewhat of a diva. The formula is interesting: it's gel-like with high color intensity (at least at first), and kind of glossy but not overly so. It's a very makeupy product, not really for the low-maintenance among us or for those in a hurry. There's a learning curve for dealing with the tiny brush, and one must overcome the natural tendency to use too much product. Which is a big part of the problem with Dior Addict It-Line. Use too much and it dries unevenly and flakes, use too little and the color is not as impressive and fades quickly.
It takes a steady hand (I don't have one) and a some patience (none, lately) to get it right with Dior Addict It-Line. It annoys me, considering all the great and easy (enough) to apply liquid eyeliners on the market. It's pretty, and It-Black is really really black, but in the end it's too fussy to really recommend it.
Bottom Line: nowhere near is enticing as the Dior shoes from the Bergdorf catalog.
Dior Addict It-Line ($31) comes in three other colors (including pink) and is available at the counters and from Sephora.
