Genetic predisposition plays a significant role, but external triggers are often responsible for provoking or worsening flare-ups:
- Excessive alcohol consumption and smoking
- Infections (such as streptococcal throat infections)
- Specific medications, including beta-blockers, lithium, and antimalarials
- Skin injury, severe sunburn, or intense physical stress
💡 Key Takeaway: Psoriasis is an autoimmune condition driving rapid skin cell buildup, often provoked by triggers like alcohol, infections, stress, or specific medications.
3. Diagnosis and Treatment Options
A dermatologist typically diagnoses psoriasis through a clinical physical exam of the skin, scalp, and nails, though a small skin biopsy may be conducted to rule out other dermatological disorders.
While there is currently no cure for psoriasis, several effective treatment pathways can control symptoms, reduce inflammation, and clear skin lesions:
- Topical Treatments: Prescription corticosteroids, retinoids, and synthetic vitamin D analogs applied directly to the skin.
- Phototherapy: Controlled medical exposure to ultraviolet (UV) light under supervision.
- Systemic Treatments: Oral medications or biologic injectables that target specific immune system pathways in moderate-to-severe cases.
💡 Key Takeaway: Modern treatments—ranging from topical creams to light therapy and advanced biologics—can effectively clear lesions and improve overall quality of life.
