I agree with healing2021, not to mention that the crusts are a haven for bacteria to develop. Try getting and using the Bepanthen cream. I find it to be a REAL moisturizer and it has no petrolatum in it so it won't turn the skin on your lips white like Aquaphor and Vaseline did to mine. Bepanthen also has vitamin B5 in it so, it really aids with the skin's recovery/regeneration.
