Displaying both well-treated and poorly-treated limbs of those with ichthyosis vulgaris. One has fine scales, which are noted to be somewhat disfiguring but not physically uncomfortable. The larger scales of the poorly-treated limb are noted to be fairly uncomfortable, and the pain associated with the ripping of keratin plates and difficulty of movement were both hindrances in everyday activities.
Ichthyosis vulgaris is by far the most common manifestation of the condition, and accounts for 95% of cases of ichthyosis. It’s an autosomal dominant condition, though in some families, entire generations can display the traits and not know it; this syndrome can appear as nothing worse than severe dry skin. This is also the least noticeable of the manifestations - though the limbs are almost always affected, the face and upper neck are often spared, and frequent application of moisturizers can often hide the condition quite well.
Also notable is that unlike lamellar and Harlequin-type ichthyosis, ichthyosis vulgaris is not present at birth, and generally does not manifest until the teenage years.
