Ichthyosis

Ichthyosis is a skin condition that makes your skin look like fish scales.

Your skin is the outer covering of your body that protects your organs and bones. It has different layers, and special cells called keratinocytes that make a protein called keratin. Keratin forms a protective layer on your skin that helps keep it healthy.

When you have ichthyosis, your keratinocytes make too much keratin, and it builds up on your skin like fish scales. This can make your skin dry, itchy, and flaky.

Ichthyosis can be passed down from your parents, which means it's genetic. It can also be caused by certain medical conditions, like thyroid problems.

Although ichthyosis can be uncomfortable, it is not contagious and does not spread from person to person. There are ways to manage it by keeping your skin moisturized and using special creams and ointments. If you have ichthyosis, you should talk to your doctor or dermatologist about the best ways to take care of your skin.
