Psoriasis and eczema are both skin conditions that can severely affect your appearance. Psoriasis is an autoimmune disease in which your body attacks its own skin, while eczema is an inflammatory condition that occurs due to environmental triggers.
Symptoms
Both psoriasis and eczema are characterized by red, dry and itchy patches on any portion of your skin. Unlike eczema, psoriasis is more extensive and can affect other parts of your body. For example, the Mayo Clinic says that psoriasis can cause joint stiffness and pitted or thickened nails.
Population
According to MedlinePlus, eczema is most common in infants. On the other hand, psoriasis can affect people of any age.
Triggers
Psoriasis is an autoimmune reaction, while eczema is a hypersensitivity (allergic) reaction to certain triggers. Stress and changes in weather can trigger both conditions. Psoriasis triggers also include stress, smoking, infections, alcohol, injury and certain medications. Dry skin, water exposure and irritants can trigger eczema, says MedlinePlus.
Diagnosis
Both conditions can be diagnosed via visual inspection. Oftentimes, your doctor may also obtain a skin biopsy (sample) to confirm the diagnosis.
Treatment
Prescription-strength medications and creams can treat both psoriasis and eczema. Light therapy is another available option to treat psoriasis.
