EOS and Chapped Lips?!

Hey guys!!
So my lips have been chapped lately, which is really weird for me. My lips usually never get chapped or dry, even in the middle of winter. I make sure to exfoliate them and always wear a lipbalm. No matter what I always put on a chapstick or something before bed. Lately I've been using and EOS lipbalm and my lips are chapped. I've heard of this happening to some other people. Has this happened to you? What did you do about it? Do you continue to use EOS? I know a lot of people really like EOS lipbalms, but I don't want to continue to use it if it's making my lips chapped. I was using Maybelline BabyLips in Quenched before this and had no problems with that...hmmm. Let me know what you guys think!!
