Skin diseases are conditions that affect the skin, hair, and nails. They can be caused by infections, allergies, immune system issues, genetics, or environmental factors.
Here is an overview of the most common types.
Inflammatory & Immune Conditions
These happen when the immune system overreacts or mistakenly attacks the body's own skin.
Eczema (Atopic Dermatitis): Causes dry, red, and intensely itchy skin patches. It's common in children and often linked to allergies or asthma.
Psoriasis: An autoimmune disease causing rapid skin cell growth. This leads to thick, raised, silvery-scaled plaques (patches), often on the elbows, knees, and scalp.
Rosacea: A chronic condition causing facial redness, flushing, visible blood vessels, and sometimes acne-like bumps, usually on the center of the face.
Hives (Urticaria): Raised, itchy, red welts on the skin's surface, typically caused by an allergic reaction to food, medication, or an irritant.
