Is Seborrheic Dermatitis The Same As Psoriasis?
There are several types of skin conditions that can cause scaly, itchy skin. Two of the most common are seborrheic dermatitis and psoriasis. Though they share some similarities, these two conditions are actually quite different.
What is Seborrheic Dermatitis?
Seborrheic dermatitis is a common, chronic skin condition that causes scaly, itchy patches on the scalp, face, and other oily areas of the body. It is thought to be caused by a combination of factors, including overgrowth of a yeast-like fungus, an overactive oil gland, and an immune system reaction. The condition is more common in oily skin types and tends to worsen in cold, dry weather.
What is Psoriasis?
Psoriasis is a chronic autoimmune disease that causes raised, red, scaly patches on the skin. It occurs when the body's immune system mistakenly attacks healthy skin cells. The exact cause of psoriasis is unknown, but it is thought to be related to genetic, environmental, and immunological factors. The condition affects about 2% of the population and can occur at any age, but most commonly begins in adulthood.
Seborrheic Dermatitis vs Psoriasis: The Differences
Though seborrheic dermatitis and psoriasis share some similarities (e.g., both can cause scaly, itchy skin), there are several key differences between these two conditions:
- Location: Seborrheic dermatitis typically affects the scalp, face, and other oily areas of the body. Psoriasis can occur anywhere on the body, but is most commonly found on the scalp, knees, elbows, and lower back.
- Scales: Seborrheic dermatitis typically causes greasy, yellowish scales that adhere to the skin. Psoriasis scales are usually thicker and whiter in color.
- itchiness: Seborrheic dermatitis is often itchy; however, psoriasis is not typically itchy.
- Duration: Seborrheic dermatitis is a chronic (long-term) condition; however, psoriasis flare-ups can come and go.
If you're not sure whether you have seborrheic dermatitis or psoriasis, make an appointment with your doctor or dermatologist. A proper diagnosis is important in order to develop an effective treatment plan.
Seborrheic dermatitis is a common skin condition that is characterized by red, scaly patches on the skin. It is often found on the scalp, but can also affect other areas of the body. Seborrheic dermatitis is thought to be caused by an overgrowth of yeast on the skin. Treatments for seborrheic dermatitis include antifungal shampoos and creams.
Psoriasis is a chronic skin condition that is characterized by red, scaly patches on the skin. It can affect any area of the body, but is most often found on the scalp, elbows, and knees. Psoriasis is thought to be caused by an overactive immune system. Treatments for psoriasis include topical creams and light therapy.
While seborrheic dermatitis and psoriasis share some similarities, they are two distinct conditions. If you are experiencing red, scaly patches on your skin, it is important to see a doctor so that you can get an accurate diagnosis and appropriate treatment plan.
