Introduction
Both eczema and psoriasis are chronic skin conditions that cause inflammation and irritation. Eczema is a condition that is typically characterized by red, itchy, and dry patches of skin. It is often associated with allergies and can be triggered by certain irritants or allergens. Psoriasis, on the other hand, is a condition that causes the skin cells to multiply faster than normal, resulting in the buildup of thick, scaly patches. It is an autoimmune condition and can be triggered by factors such as stress, infections, or certain medications.
Symptoms
While both eczema and psoriasis can cause red, inflamed skin, there are some differences in the types of symptoms they produce. Eczema commonly causes intense itching, dryness, and a rash that can appear on different parts of the body, such as the hands, face, or feet. The rash may also be accompanied by blisters that ooze or crust over. Psoriasis, on the other hand, often presents as thick, red patches of skin that are covered with silvery scales. These patches can appear on the scalp, elbows, knees, and lower back. Psoriasis can also cause itching and burning sensations.
Location
The location of the rashes or patches can also help differentiate between eczema and psoriasis. Eczema tends to occur on the flexural areas of the body, such as the inside of the elbows or behind the knees. It may also affect the face, hands, and feet. Psoriasis commonly affects the scalp, elbows, knees, and lower back. It can also involve the nails, causing pitting, discoloration, and thickening.
Triggers
Identifying triggers can also be helpful in distinguishing between eczema and psoriasis. Eczema flare-ups are often triggered by exposure to irritants or allergens, such as certain fabrics, soaps, lotions, or dust mites. Stress, sweating, and changes in temperature can also worsen eczema symptoms. Psoriasis triggers can include stress, infections, injuries to the skin, certain medications (such as beta-blockers or lithium), and even weather changes.
