It is usually an autosomal dominant inherited disease (often associated with filaggrin), although a rare non-heritable version called acquired ichthyosis exists.

[6] The symptoms of the inherited form of ichthyosis vulgaris are not usually present at birth but generally develop between three months and five years of age.

While most individuals with this condition can expect a regular lifespan, potential complications include vitamin D deficiency and hearing problems due to ear scaling.

As the primary therapeutic approach, physicians often recommend using creams containing 10% urea, along with ceramides and other moisturising compounds, to manage ichthyosis vulgaris.

People with mild cases have symptoms that include scaly patches on the shins, fine white scales on the forearms and upper arms, and rough palms.

For children and adolescents, psychological concerns may include inconsistent self-image, mood fluctuations due to cyclical outbreaks, a tendency to addiction, the possibility of social withdrawal when skin is noticeably infected, and preoccupation with appearance.

[14] Another common condition associated with ichthyosis vulgaris is keratosis pilaris (small bumps mainly appearing on the back of the upper arms).

[15] Ichthyosis vulgaris is mainly diagnosed based on the clinical features of the patient mainly the physical exam findings and the personal and family histories.

History of the age of the onset, and using family pedigree to clarify the pattern of inheritance can help to specify ichthyosis vulgaris among other types of ichthyoses.

A new emulsion containing urea (10%), ceramides, and natural moisturising factors, applied twice daily, can be beneficial for individuals with hyperkeratotic and dry skin.

In cases of acquired ichthyosis vulgaris, treatment primarily involves addressing the underlying systemic condition, often leading to symptom improvement.

Ongoing research aims to assess and compare the physical and chemical properties of various topical emollients to determine their efficacy in managing ichthyosis vulgaris.
