@burcinc-- Those are some really good questions!
I would say that 90% of shiny lip colors are moisturizing. Of course, there are some that aren't but that's pretty rare. The reason is because in order for the product to have a shiny finish, it needs oils and moisturizers. So almost always, you won't have a problem.
There are many different kinds of emollients (moisturizers) used in cosmetics. Rather than trying to figure out the emollients in a lipstick, it's probably better to look out for ingredients that are drying like alcohol.
I personally like shiny and shimmery lip glosses with a brush applicator. It does require some practice but if you line your lips with the brush first and then fill it in, it'll be fine. Otherwise, the easiest to use applicator is probably a slanted foam type applicator. You can't go wrong with it. If all else fails, just use your finger!
