Ichthyosis vulgaris is an inherited skin disorder that causes dryness and scaly skin. It could either be genetic, meaning you can get it from your family, or it could be acquired, or it can just occur on its own. But in most cases, it is an inherited or a genetic disorder. The primary cause of the condition is the skin's inability to shed it's dead skin cells, leading to the accumulation of the same in patches that resemble a fish scale. This is why ichthyosis Vulgaris is also known as the 'fish scale disease'. The normal human skin tends to shed its dead skin every few days or every few weeks. That is not the case in this condition and it can lead to excessive dryness in the skin and excessive scaliness in certain parts of the body. It can also occur in larger areas or the entire body.
