No cause is directly attributed to psoriasis. Like most forms, skin cells continuously grow and regrow before the skin can naturally shed old cells. This rapid growth leads to thickened, flaky, reddened skin.
The scaly, itchy skin condition.
Psoriasis is a chronic skin condition that causes thick, scaly, and often itchy patches of skin. It can vary from mild to more severe and may appear suddenly or develop gradually over time.
It is believed to be related to an overactive immune response that speeds up the skin’s natural growth cycle, leading to a buildup of skin cells on the surface of the skin.
Common Types of Psoriasis
- Plaque psoriasis: The most common form, causing red, raised patches with silvery scale, often on the elbows, knees, scalp, and lower back
- Guttate psoriasis: Small, drop-shaped spots that often appear suddenly, sometimes after a strep throat or other infection
- Inverse psoriasis: Smooth, red patches found in skin folds such as the armpits, groin, and under the breasts
- Pustular psoriasis: White, pus-filled bumps surrounded by red, inflamed skin
- Scalp psoriasis: Scaling, flaking, and redness on the scalp, sometimes extending beyond the hairline
- Nail psoriasis: Pitting, discoloration, thickening, or separation of the nails
- Palmoplantar psoriasis: Thickened, cracked, or scaly skin on the palms of the hands and soles of the feet

Frequently asked psoriasis questions.
What is the cause of psoriasis?
Who is more prone to psoriasis?
Men, women, and children of any race or age can suffer from psoriasis. Although not contagious, genetics may play a role in the likeliness of contracting this disease.
Like other dry, itchy skin conditions, psoriasis can be treated through over-the-counter (OTC) moisturizers, ointments, lotions, topical creams, and shampoos.
For more serious conditions, prescription medication or UV light therapy may be recommended. Consult a specialist at Idaho Dermatology for a comprehensive diagnoses and treatment plan.
