Psoriasis is not just a “skin condition,” although, by the looks of it, it’s easy to understand why that is how it’s mainly identified.
In reality, psoriasis actually starts underneath the skin, in the form of a chronic disease of the immune system that can range from mild to severe.
Normal, healthy skin has a renewal cycle that takes about a month, where the old skin is shed and new skin cells are produced. In a psoriasis afflicted person, this cycle happens every 3 to 4 days.
This pushes new skin cells to the surface before your body can shed the existing skin, effectively piling up on each other, creating the red, flaky, itchy patches of inflammation that psoriasis is known for.
It is important to highlight that Psoriasis is not contagious, one person cannot “catch it” from another. Psoriasis is a disease of the immune system and is not something you can catch.
