After several weeks of nice soft lips, all of a sudden they became really sore and peeled again!
Probably a coincidence, but it happened the day after I ran out of non sodium lauryl sulphate toothpaste.
Because the cream was working so well I started slacking off applying it. I'm still confident the cream slows down the whole process and makes my lips look normal for longer.
Picture attached when of when they became bad again.
