My son is 14 yrs old and has issues around and on his lips extreme dryness. We showed to many doctors they all recommended to apply cortisone and then Vaseline. This has been going on for 10 years. Now recently his lips has started forming discoloration and he still has dryness. He has been going through tough times. I can send the picture if any doctor would like to see how it looks. Any help is much appreciated.
