Eczema Versus Psoriasis: Are You Treating the Right Condition?
The season of winter skin freakouts is in full swing. If you’re noticing annoying new areas of irritation and have promptly taken to WebMD to self-diagnose and treat your symptoms, we urge you to stop. Though you are not alone, Googling medical conditions almost always results in diagnosing yourself with the worst possible ailment (at least, that’s been our experience). Some of the most common skin problems that flare up this time of year happen to appear remarkably similar, but the treatments are not interchangeable. Enter: the dermatologist. To clear up the differences between eczema and psoriasis, we called in Dr. Vermén Verallo-Rowell. Keep reading to find out if you’ve been treating the right condition.
It’s easy to mistake the two because both eczema and psoriasis look like patches of red, irritated, even scaly skin. “However, eczema starts as wet, spongy, or bubbly patches,” Dr. Verallo-Rowell says. “Those of psoriasis are dry from the very start.” But psoriasis patches can become wet due to frequent itching, infection, or an allergic or irritant reaction to topical treatments. The key is to pay attention to how they first appeared.
There are several forms of eczema and it’s estimated that it affects nine to 30 per cent of Americans. One form, atopic dermatitis, is primarily inherited from other family members, but is triggered by dust mites, hot and humid weather, and winter’s cold, dry weather. Contact dermatitis, an acquired skin inflammation, appears on areas of the skin that have come in contact with irritants. Dr. Verallo-Rowell says dyes from clothing or hair colour, metals in jewellery and clothing accessories, fragrance in detergents and personal care products, and preservatives in beauty products can all trigger this type of eczema. Hand eczema and dyshidrotic eczema (bubbles that appear on fingers, palms, and soles of feet) are often caused by a combination of factors. According to Dr. Verallo-Rowell, frequent hand washing, harsh soaps and ingredients in lotions, and general winter skin dryness all contribute to these types of eczema.
“Psoriasis is an immunologic disease that is in part genetic, which then becomes triggered by multiple factors including infection, trauma, chemicals, irritation, poor diet, and other internal causes that initiate inflammation in the body such as obesity, lack of sleep, stress, and certain drugs like beta-blockers for hypertension and anti-depressants,” Dr. Verallo-Rowell says. While both conditions are closely tied to inflammation, your body’s overall health plays a major role in psoriasis. As psoriasis becomes moderate to severe, Dr. Verallo-Rowell says there is a greater tendency to develop co-existing diseases like heart disease, hypertension, diabetes, depression, and obesity.
Dr. Verallo-Rowell says you can treat psoriasis similarly to the way you would treat eczema, although you need to be even more cognisant of trauma to the skin, your skin’s history, and the stressors in your life. She also notes that since the triggers vary greatly person to person, treatment decisions are best when they come from your doctor. “When psoriasis becomes moderate (five to 20 per cent body surface involvement) to severe (more than 20 per cent body surface involvement), or even when less than these but appearing in difficult areas such as hands and feet, genitals, face, scalp, or in conjunction with arthritis, your dermatologist can prescribe drugs that can have amazing results for psoriasis,” Dr. Verallo-Rowell says. If your problem sounds more like psoriasis than eczema, see a dermatologist to determine the best treatment options for you.
Regardless of the winter skin ailment you’re treating, Dr. Verallo-Rowell says it’s best to follow a few general good health principles. Your top priority should be maintaining a healthy diet filled with plenty of fruits and vegetables and lean proteins, especially oily fish, like tuna, salmon, sardines, and shellfish. Avoid processed foods and sweets, and try to limit carbohydrates. Getting a good seven to eight hours of sleep every night and exercising regularly are also important.
