Rant & Rave: Guerlain Weekly Features 2/16/15February 16, 2015 Share: Tell us what you love and hate about Guerlain!my answer: I love so many of their base/face products, along with limited edition highlighters and most of their lip products. Their newer nail lacquer is also excellent, though the shade range could use some less basic, more unique shades in it! I don’t love their eyeshadow formula more often than not (sometimes it is really good, sometimes it is a big miss). I really like how they tend to put out more luxurious packaging with less plastic components. I really wish they had refills for Rouge Gs, and they discontinue formulas very frequently!
