Differences between Atopic and Seborrheic Dermatitis

What is the difference between atopic and seborrheic dermatitis? In the medical field, when we talk about dermatitis, we generally refer to inflammation of the skin. This can be caused by various factors capable of triggering an annoying and unaesthetic skin reaction. Based on the triggering causes, the affected areas of the body, and the way it presents, different types of dermatitis have been identified, including:

  • Atopic dermatitis;
  • Seborrheic dermatitis;
    • Allergic contact dermatitis;
    • Stress-induced dermatitis  (link to the article: How to Recognize Stress Dermatitis);
    • Irritant contact dermatitis;
    • Dermatitis herpetiformis.

    Focusing on the first two types, we can say that they differ from each other in several factors. The first presents with redness and itching, while the second affects areas with sebaceous glands, leading to the formation of white-yellowish scales that detach from the skin. Here's what we need to know about atopic and seborrheic dermatitis and, more importantly, how to counteract them both.

    Atopic and Seborrheic Dermatitis: Differences

    What are the differences between atopic and seborrheic dermatitis? The first causes itching and redness of the skin. Its manifestation can interfere with daily life. Itching can compromise a good night's sleep, reducing concentration. The red patches can also affect self-esteem and social relationships. Like most dermatitis, atopic dermatitis appears on visible parts of the body, creating difficulties for those affected in establishing relationships with others. The most affected areas include hands, feet, wrists, ankles, inner elbow folds, back knee folds, face, neck, chest, and the area around the eyes.

    Atopic dermatitis can arise due to:

    • Genetic factors;
    • Environmental factors;
    • Immunological factors.

    Additionally, changes in seasons and psychophysical stress can exacerbate the clinical picture of those affected. It can manifest from birth with an abundant cradle cap or in the first months or years of life. Alternatively, it can suddenly appear in adulthood. It is estimated that 2% to 8% of people in Italy are affected by it.

    Unlike atopic dermatitis, seborrheic dermatitis affects areas of the skin rich in sebaceous glands, such as the scalp, nasolabial folds, retro-auricular areas, supraorbital arches, and the sternal area. It manifests with scales that do not adhere to the scalp and, in more severe forms, with erythematous plaques covered by oily yellowish scales.

    Another difference concerns the age of onset. Seborrheic dermatitis typically appears around the ages of 30-40. Additionally, it has been observed that this inflammation mainly affects the male population. Factors causing its onset may include hormonal imbalances, psychophysical stress, and genetic predisposition.

    How to Treat Atopic Dermatitis?

    The treatment for atopic dermatitis varies depending on its severity and the age at which it appears. Mild forms are often treated with topical corticosteroid medications, some locally used immunomodulators, and phototherapy. The dermatologist may also consider prescribing oral antihistamines to control itching. Local or systemic antibiotic therapies may be used when there is bacterial superinfection of skin lesions. In severe forms of atopic dermatitis, systemic steroids or other immunosuppressants or monoclonal antibodies may be prescribed.

    In any case, to prevent its onset and counteract undesirable effects, dermatologists recommend avoiding excessively long and frequent baths, as well as the use of aggressive soaps. When exposing oneself to the sun, it is essential to use specific sunscreens and incorporate moisturizing-soothing creams into daily skincare. Ischia SPAEH products come to the rescue. In addition to the best products for treating psoriasis, there are creams, soaps, and sunscreens specifically designed to counteract and prevent atopic dermatitis. Each thermal water cream provides intense hydration and numerous benefits for the skin.

    How to Treat Seborrheic Dermatitis?

    How to treat seborrheic dermatitis? Specialists recommend using products containing ketoconazole, ciclopirox, selenium sulfide, or salicylic acid, especially in mild cases. In more severe cases, topical corticosteroid treatments may be used. The advice, as with atopic dermatitis, is to avoid excessive baths, frequent washing, aggressive cleansers, and sun exposure without suitable skin protection. Leveraging the benefits of Nitrodi thermal water, Ischia SPAEH has created a specific treatment against psoriasis and dermatitis.
