There are many types of ichthyosis. Most are inherited. Rare types are part of genetic "syndromes" that are associated with deafness, tooth disorders, hair disorders, or other problems. Some types that involve scales in the warm, moist creases of the skin (like the inner arms, backs of legs or underarms) are especially prone to infection and foul-smelling odor.
The following treatments are aimed at moisturizing and repairing the skin barrier:
- Mineral oil
- Petrolatum (similar to petroleum jelly)
- Lotions that contain urea or alpha-hydroxy acids (such as lactic acid or glycolic acid)
Ichthyosis should be evaluated by a dermatologist. This doctor will determine the type, suggest the best treatment and look for associated syndromes.
