Psoriasis: Causes, Treatments, and What Really Works

When your skin turns red, thick, and covered in silvery scales, it’s not just dryness—it’s psoriasis, a chronic autoimmune condition where the immune system mistakenly attacks healthy skin cells, causing them to grow too fast. Also known as plaque psoriasis, it’s the most common form and affects nearly 8 million people in the U.S. alone. This isn’t contagious, and it’s not caused by poor hygiene. It’s your body’s own defenses going haywire, often triggered by stress, infections, cold weather, or certain medications.

People with psoriasis often deal with more than just skin symptoms. Many also develop psoriatic arthritis, a type of inflammatory joint disease that causes stiffness, swelling, and pain, often in the fingers, toes, and lower back. And because psoriasis is linked to inflammation throughout the body, those with the condition have a higher risk of heart disease, diabetes, and depression. It’s not just a skin problem—it’s a whole-body issue.

Treatment doesn’t mean one-size-fits-all. For mild cases, topical treatments, like corticosteroid creams, vitamin D analogs, and coal tar can bring relief. But when the patches spread or don’t respond, doctors turn to systemic medications, including biologics, methotrexate, or oral retinoids—drugs that work inside your body to calm the immune response. Some people find relief with light therapy, while others swear by lifestyle changes like quitting smoking or cutting out alcohol. The key is finding what works for you, not what’s cheapest or easiest to find.
