What Is Psoriasis?
Psoriasis is a skin condition where the skin renews itself too quickly. This leads to a buildup of skin cells on the surface.
As a result, thick, scaly patches form. These patches may appear on the scalp, elbows, knees, or other parts of the body.
Quick self-check:
- Do you have thick, scaly patches on your skin?
- Do they look silvery or white on top?
- Do they come and go over time?
- Are they sometimes itchy or dry?
