Thanks very much for your question. The appearance of cracks or tears at the corners of the mouth and nose can be attributed to various vitamin deficiencies. It’s difficult to tell you exactly what this may be without investigating with blood tests. Are you taking at least the very basics? A good multi-vitamin, omega’s, calcium and antioxidants? Sometimes just simply sorting that out will sort out various issues in the skin and body. There are other things you can also do to deal with the immediate problem, namely the use of a good topical barrier repairing product, such as Lamelle’s Serra Restore Cream, or Lamelle’s Barrier Repair Cream, or Neostrata’s Problem Dry Skin Cream.
