My 23 yr old keeps getting Chapped lips mainly in the corners of his mouth. He has quite wrinkly lips and in each crease it?s getting sore and crusty. The first time I bathed them each day cleaning out any gunk and put some Vaseline on twice a day. That cleared it up but now it?s come back. I?m doing the same again but he?s never had this in the 13 years I?ve had him but it?s happened 3 times this winter. Has anyone had anything similar? I?m wondering if it?s some sort of deficiency or just the bitter weather.
