All three of these full-sized liquid lips are available on the Anastasia Beverly Hills website but else where they are sold as retailer's exclusives. Really, I think it would be much simpler just to order directly from Anastasia.
Starfish is my favorite of the 3, ABH describes it as a Peach Sand. It's a really gorgeous medium brown with a peachy undertone.
Rock Sand is a Rosy Brown, it's really one of those standard fall mauve-browns that is quite universally flattering. To me it is one of the those go to shades for the autumnal season.
Trouble is the trendiest shade of the three, they describe it as a mauve nude, seems like every brand is coming out with these grey lilac shades. To be honest it just is not really my vibe, I just don't like the way these colors play with my skin shade and tone. But I see artist like Jessica Haze who is very rocking them and they look amazing on her.
