Hi there.
This is an interesting question.
From what I gather, the effect is primarily to isolate the lips to avoid 
further loss of water. A bit like putting on a coat when it's cold 
outside. The presence of one set of molecules can help to soften dry skin 
and another compound is sometimes added, which is supposed to bind water. 
As is sadly often the case in cosmetics, the science behind it can be a 
bit… doubtful. I have read between the lines at several lip-gloss 
manufacturers' Internet sites, so you may excuse me if I don't give you 
any references: there are many of their claims I don't believe in, and 
relaying this information at a Science site such as madsci.com would be 
wrong... and these companies would hate me for telling you so! 
Hope this answers your question. Best regards,

Erik von Stedingk
