When first applying it, it does look a little grey (a common thing with Korean BB creams) after a little while it will oxidize. During summer time I have to blend it out with a darker shade. I usually blend with Missha perfect cover BB cream in nr 31 (which is way too dark for me so I only use to add warmth to my colder shades).
The first time I used this I was really surprised. I really can’t feel the product on my lips at all. Just this feature is a big win for me. I did not exfoliate my lips before using it the first time, and I did think I really needed to either. Normally when it comes to liquid lipsticks they tend to dry my lips out really fast and if I don’t exfoliate my lips first, my lips look really bad. But with my first use with this one I didn’t, and still no problem.
