Sulfur: What are its benefits against eczema?

Various treatment options are available for eczema, including topical corticosteroid creams and ointments, oral medications, and moisturizing creams. Sulfur also presents a potential avenue. Here, we will examine what we know about the use of sulfur in the treatment of eczema, including its potential benefits, effectiveness, and risks.

Eczema: What is it?

Eczema refers to a non-contagious skin condition that causes redness and inflammation. It also presents with itching, which can lead to bleeding in cases of excessive scratching.

The causes of eczema involve numerous factors such as an overactive immune system, genetic predisposition, environmental factors, and harsh chemicals. These, in conjunction with a dysfunction of the skin barrier, can promote an eczema flare-up. When the skin barrier no longer provides protective function, skin moisture evaporates, allowing irritants to act freely.

Eczema flare-ups also occur due to specific trigger factors. These can include respiratory infections, the common cold, detergents, soaps, extreme temperatures, and contact with certain animals or rough fabrics such as wool.

The symptoms accompanying eczema can range from mild to severe. Mild signs of the disease manifest as dry skin with scales. For severe symptoms, they may correspond to persistent redness and itching followed by cracking and oozing.

Is sulfur an effective treatment for eczema?

The sulfur has been used for a long time in traditional medicine to treat various skin conditions. Some claim that products containing sulfur help to alleviate the symptoms of eczema. A study conducted in 2017 on mice also demonstrated that bathing in spring water containing several minerals, including sulfur, reduced inflammation similar to that of eczema.

However, up until now, the only evidence supporting its use is anecdotal and remains inconclusive due to limited scientific proof. Furthermore, no study has examined the impact of sulfur on eczema in humans to confirm its effectiveness. Therefore, additional research is necessary to confirm its effects.

However, sulfur possesses several properties that could be beneficial to individuals suffering from inflammatory skin conditions, such as eczema

  • Anti-inflammatory property: A 2018 study suggests that mineral-rich waters, including sulfur, could alleviate eczema and psoriasis. It would particularly help to reduce skin inflammation, a common symptom of eczema, and soothe irritations.

  • Anti-microbial action: Certain species of bacteria can exacerbate the symptoms of eczema or lead to secondary infections. Indeed, a small clinical trial revealed that the presence of Staphylococcus aureus worsens the symptoms of hand eczema. However, sulfur could help inhibit their growth with its anti-microbial properties.

  • Keratolytic Effect: Sulfur appears to have keratolytic properties. Besides removing dead cells, these keratinocyte agents also have the ability to bind moisture to the skin, which means it can soften and hydrate eczematous skin.

  • Drying Effect: Sulfur has a drying effect on the skin, which can be beneficial for individuals suffering from weeping eczema lesions.

How do we use sulfur to treat skin conditions such as eczema?

Sulfur is used in various ways to treat skin conditions:

  • Topical Application: Sulfur is often found in the form of pastes, ointments, creams, or lotions that are applied directly to the affected skin areas to reduce inflammation and control itching associated with eczema. The creams and lotions may contain a combination of sulfur and other ingredients. While some anecdotal evidence supports their use, additional research is needed to determine their actual effectiveness.

  • Sulfurous Baths: Some people use water containing sulfur or add sulfur-based bath additives. They claim that homeopathic preparations based on sulfur help them manage their eczema. According to the National Center for Complementary and Integrative Health, limited evidence confirms that homeopathy is a viable treatment for any health problem.

  • Sulfur Soaps and Shampoos: These products often contain sulfur, which can be beneficial for treating various skin conditions. They cleanse the skin or scalp during bathing or showering. The sulfur thus comes into contact with the skin, reducing inflammation and irritation. Although sulfur soap may be helpful to you, it can cause dryness or skin irritation. It is best to use it sparingly and stop using it if you experience adverse effects. While some anecdotal evidence supports their use, additional research is needed to determine their actual effectiveness.
