This was the second Lush lip item I've used and it will definitely be the last.
I'm not sure what the other flavours are like but I found the Popcorn one to be totally off-putting and 'chemically' tasting. It certainly wasn't something you would want to lick off and in fact I had to scrub my teeth each time I used it to get rid of the taste.
It sort-of worked to smooth my lips but not as successfully (or cheaply) as just using a damp face flannel which was my old routine.
There are definitely cheaper alternatives and I would look at making my own version at home in future.
I think this stuff is great! I've tried the bubble-gum one and found that it's really good to use before applying your lip gloss/lip stick. And it tastes SO good!
Tips: Apply to lips with fingers and scrub, this removes any skin and makes your lips smooth and soft for when you put on your lip stick!
