What Is Psoriasis?
Psoriasis is a chronic autoimmune condition where skin cells build up too quickly, forming thick, scaly patches. It is not contagious and often comes in cycles of flare-ups and remission.
Common Symptoms
- Red patches of skin covered with silvery scales
- Dry, cracked skin that may bleed
- Itching, burning or soreness
- Thickened or ridged nails
- Stiff, swollen joints (psoriatic arthritis)
Common Types
| Type | Description |
|---|---|
| Plaque psoriasis | Most common — raised, red patches with silvery scale |
| Guttate psoriasis | Small, drop-shaped spots, often after a throat infection |
| Inverse psoriasis | Smooth, red patches in skin folds |
| Pustular psoriasis | White pustules surrounded by red skin |
| Psoriatic arthritis | Joint pain and swelling alongside skin symptoms |
Common Triggers
- Stress
- Skin injury (cuts, sunburn)
- Infections, especially strep throat
- Certain medications
- Cold, dry weather
- Smoking and heavy alcohol use
Treatment Options
- Topical corticosteroids and vitamin D creams
- Phototherapy (UV light treatment)
- Oral or injectable systemic medications
- Biologic drugs for moderate-to-severe disease
- Moisturising regularly to reduce flare severity
Important: Psoriasis severity and treatment response vary widely. See a dermatologist for an individualised treatment plan.
