Now I know what the real culprit is: SLS (Sodium Lauryl Sulfate) allergy!

Yes brillig! Me too! I've tried sooo many treatments trying to get rid of the chelitis for two years now! After MUCH investigation on the internet, I switched to a toothpaste without Sodium Lauryl Sulfate, in my case Sensodyne Gentle Whitening, and presto chango, all irritation gone by evening! It's been over a week now, and my mouth is still normal. I thought initially, it was a beeswax allergy and quit using my lip products, but continued to have issues. Now I know what the real culprit is. Not sure why it suddenly developed after many years of using toothpastes with that ingredient. Hope this will help others! Tweet
