If you're addicted to Carmex and can't figure out why, chances are it's because you're allergic to something in it.
Contrary to all those rumors you've heard about your Carmex lip balm containing glass shards that force you to reapply all the time, The Cut reports that the real reason you're addicted has more to do with other ingredients possibly irritating your skin.
The article suggests that if you tend to find wool sweaters itchy, you might also find that you react negatively toward Carmex due to an ingredient it contains called lanolin, which is a substance found in wool.
Other ingredients people might be reacting to are salicylic acid (a common acne treatment), beeswax (which is the second most common allergy), or benzocaine, which can actually cause chapped lips if you're allergic to it. Kind of makes sense that you would always want to be reapplying, huh?
If this is the case for you, try opting for a different kind of lip balm instead.
