Colors from left to right, clockwise: Hot, Delish, Tempt and Euphoria

I knew that I was a makeup whore - ie, someone who loved all different kinds of makeup, across categories and price points, but until I wore the same brand of lipsticks for 7 days straight, I never realized how fickle I am. I won't lie, it was pretty tough to stick with my Lip Perfection challenge, but I am please to announce that another lip product did not touch my lips during Fashion Week. (I chronicled most of the days on my Tumblr.)

Because of my new red hair and complexion, I chose to wear Hot, Delish, Darling, Sultry, Spellbound, Tempt and Euphoria for the challenge. These colors are from the Runway Collection, however the entire collection features 15 colors that complement a wide range of skin tones. I also paired a couple of the colors with Lip Perfection liners in Seduce and Passion.

What surprised me most about the challenge was that I didn't feel like I had to constantly reach into my bag for lip balm. With the exception of Sultry and Delish, the formula didn't need any additional moisturizers (I mixed a teensy bit of balm to keep the more nude colors from laying a bit too flat on my lips). Even more surprisingly, Hot and Tempt lasted dearly all day without needing to be reapplied. Those are some serious pigments!

After a bit of research, I learned why CoverGirl's Lip Perfection lipsticks are so different - the formula uses olive oil as an active moisturizer, plus white tea for it's anti-aging properties, a "butters complex" (ie, shea avocado and aloe) for that smooth finish and a silk protein that helps to improve the condition of your lips over time.

The Runway Collection, which I was focused on for this experiment, features 15 of Lip Perfection's expansive 44 shade collection. I know some of you ladies have had to try these lipsticks. Which shades are your favorite?
