What Causes Psoriasis? Exploring Triggers and Risk Factors

Woman touching her arm with psoriasis in Los Angeles, CA Psoriasis is an autoimmune condition that causes rapid skin cell buildup, leading to scaling, inflammation, and redness. While its exact cause isn’t fully understood, a combination of immune system dysfunction and genetic predisposition plays a central role. Let’s explore the most common triggers and risk factors that contribute to the onset and flare-ups of psoriasis.

At Skin & Beauty Center, California’s most comprehensive skin care center, board-certified dermatologists offer expert diagnosis and treatment for psoriasis and other complex skin conditions. Their full-service medical, surgical, and cosmetic dermatology team utilizes advanced tools and techniques to help restore skin health and confidence.

Key Triggers of Psoriasis

Certain external and internal factors can trigger or worsen psoriasis symptoms:

  • Stress: Emotional stress is a significant trigger. It can both initiate a flare and make existing psoriasis worse due to its impact on immune function.
  • Infections: Bacterial or viral infections, especially streptococcal throat infections, are known to trigger guttate psoriasis, particularly in children and young adults.
  • Skin Injuries: Cuts, scrapes, sunburns, or even vaccinations can lead to what’s known as the Koebner phenomenon, where psoriasis develops at the injury site.
  • Weather: Cold, dry climates can dehydrate skin and exacerbate symptoms. Conversely, warm, sunny environments often improve the condition due to exposure to UV light.
  • Medications: Certain drugs, including beta-blockers, lithium, and antimalarials, can induce or worsen psoriasis.
  • Lifestyle Factors: Smoking and excess alcohol consumption are both linked to more severe psoriasis and reduced treatment response.

Common Risk Factors

  • Family History: Genetics play a major role. If one or both parents have psoriasis, the chances of developing it are significantly higher.
  • Immune Disorders: Since psoriasis is autoimmune in nature, individuals with other immune-related conditions may be more susceptible.
  • Obesity: Excess weight is linked to both increased risk and severity of psoriasis, especially inverse psoriasis, which affects skin folds.
  • Age: Psoriasis can appear at any age but most often begins between the ages of 15 and 35.
