I use to have that with extremely glittery lip gloss so I just didn't use it. I no longer have the problem. why don't you just use chapstick? They have some now that are shinier if that is what you're looking for
I love gloss pots too! another thing you could try if all else fails is put a lip stain on 1st then top with 100% pure lanolin! It is all natural and shiny like a gloss yet all natural (they yse it for breast feeding moms) but it will leave your lips so incredibly hydrated and soft and with a stain you could literally make your own gloss in any color you choose! HTH
I sometimes have that problem too. I get these small painful bumps on the edges of my lips. It only happens with thick, sticky lip glosses though. I found Clinique and Tarte glosses to be really good though.
