If you’ve ever noticed red, scaly patches on your skin that don’t seem to go away, you might be dealing with more than just dry skin. Plaque psoriasis is one of the most common types of psoriasis — and its causes may not be what you expect.
It’s Not Just a Skin Issue
Plaque psoriasis is often mistaken for a skin condition, but it actually goes deeper. It’s a chronic autoimmune disease, meaning your immune system attacks healthy skin cells by mistake, causing rapid skin cell buildup.
The result? Inflamed, raised, and flaky patches that can show up on your elbows, knees, scalp, back — or just about anywhere.
So What Triggers It?
While the exact cause of psoriasis isn’t fully understood, we do know there are several surprising triggers and risk factors:
Stress: A major flare-up factor that’s often underestimated.
Infections: Especially strep throat or respiratory infections.
Who Gets It — And Why?
Anyone can develop plaque psoriasis, but it often appears between the ages of 15 and 35. Having a family history of psoriasis increases your risk, but even people with no known genetic connection can develop it — especially if they’re exposed to certain triggers.
What Are the Symptoms?
Plaque psoriasis often causes thick, red patches of skin covered with silvery-white scales. Many people also experience itching, burning, or soreness. Symptoms can vary in severity and may come and go in cycles, affecting daily comfort and skin health.
Bottom Line
Plaque psoriasis isn’t just about skin — it’s about your immune system, your stress levels, your environment, and sometimes, your genes. If you’ve been noticing persistent patches or irritation, don’t brush it off as dryness.
Understanding the root causes of plaque psoriasis is the first step toward real relief.
