Eczema (Atopic Dermatitis)

Atopic dermatitis (eczema) is a chronic, relapsing inflammatory skin condition characterised by intense itch, dry skin, and eczematous patches. It is the most common inflammatory skin condition worldwide, affecting up to 20% of children and 3% of adults.

Atopic dermatitis involves three interconnected problems: skin barrier dysfunction, immune dysregulation (Th2-skewed inflammation), and microbiome imbalance (particularly overgrowth of Staphylococcus aureus). Effective management typically requires addressing all three.

How peat may help

Barrier support. Peat contains polyphenols and humectant compounds that may support skin hydration and barrier integrity. The colloidal properties of peat preparations create a transient film on the skin that reduces transepidermal water loss.

Anti-inflammatory. Humic acids reduce Th2-pathway inflammatory mediators. While peat cannot replicate the potency of topical corticosteroids or calcineurin inhibitors, it may provide useful anti-inflammatory support during maintenance phases or mild disease.

Antimicrobial support. The presence of S. aureus on eczematous skin correlates strongly with disease severity. Peat’s antimicrobial properties — attributed to humic acids and phenolic compounds — may help reduce S. aureus colonisation. This is particularly relevant given growing concern about antibiotic resistance.

Balneotherapy for eczema

Peat bath treatment for atopic eczema has been used in European spa medicine and is occasionally included in modern balneotherapy protocols. Some clinicians combine peat bathing with phototherapy (NB-UVB), taking advantage of the skin-softening effects of peat to improve UV penetration.

The available evidence is limited to case series and small observational studies. The results are generally positive — improved SCORAD (SCORing Atopic Dermatitis) scores, reduced itch, improved sleep quality — but controlled trial data is sparse.

Important considerations

Acute flares. During active flares with broken or weeping skin, new topical products should be introduced very cautiously. Peat preparations applied to compromised barrier skin may cause stinging. In these phases, prescribed medical treatment takes priority.

Test reactions. Some people with atopic dermatitis have multiple contact sensitisations. Patch testing a new peat product on a small area before full use is advisable.

Complementary, not primary. For moderate-to-severe atopic dermatitis, peat treatments are a supportive measure alongside prescribed therapy — topical corticosteroids, calcineurin inhibitors, or for severe disease, dupilumab or other biologics.
