I was first introduced to Blistex in 2013 when I went on Oratane to treat my acne. Side effects or Oratane is that it makes you lips extremely dry and chapped and sensitive to the sun.
I honestly did no think it would be that bad but it was awful. My lips were constantly flakey and peeling. I went to Mkem, and they recommended Blistex. It was such a great relief and helped with the excessive dryness and cracks. Due to my lips being very chapped it did burn a little when I applied, however it was a pleasant burn, it felt like relief. To this day I still use Blistex as my lips never returned back to normal.
I would recommend Blistex to anyone with chapped/dry lips or to even use it as a primer before applying lipstick.
