I've tried SO many different lip treatments, I think my main problem is that I lick my lips/bite them/play with them too much.
I've tried Lipsmackers in different forms, chapstick, neutrogena lip moisturizer.. out of those three the neutrogena lip moisturizer was the best, it even has spf 15, but it makes my lips feel dirty now.. but the stick isnt dirty. weird.
I've used CLINIQUE Princess Livia's lip soother before, it was soo good, it went on so easily, smelled/tasted amazing, and it left my lips so soft and stayed on really good but didn't add a weird glossy effect or make them darker.
But the tube I tried was really old.. so I got a new one, and holy shit, it was even better! The scent/color/everything about it was different but it was still great. I've never tried a lip product like it before, It sucks that it isn't very well known/easy to buy. But I really like it!
