Psoriasis is a long-term skin condition where the immune system causes skin cells to grow too quickly. This leads to thick, red, scaly patches on the skin.
🧠 What it looks like
Common signs include:
- red or pink patches of skin
- silvery-white scales
- dry, cracked skin that may bleed
- itching or burning sensation
- thickened nails (in some cases)
It most often appears on:
- elbows
- knees
- scalp
- lower back
🔍 Why it happens
Psoriasis is an autoimmune condition, meaning:
- the immune system becomes overactive
- it speeds up skin cell production
- cells build up on the surface instead of shedding normally
Triggers can include:
- stress
- infections
- cold weather
- certain medications
- smoking or alcohol
⚠️ Is it contagious?
No. Psoriasis is not infectious and cannot spread from person to person.
💊 Treatment options
There is no permanent cure, but it can be controlled with:
- medicated creams (steroids, vitamin D analogs)
- light therapy (phototherapy)
- oral or injectable immune treatments in severe cases
- moisturizers to reduce dryness
🧠 Bottom line
Psoriasis is a chronic but manageable immune-related skin condition. Many people live normal lives with proper treatment and skin care.
If you want, I can explain how to tell psoriasis apart from eczema, since they are often confused.
