NCT06499766

Brief Summary

The purpose of the study is to test the selected methods and to explore the effect of nature-based exposure on immunological biomarkers and the condition of atopic skin. Overall purpose is to test the safety and feasibility of a new nature-exposure method on atopic skin: regular use of lotion containing inactivated microbial extract that mimics Finnish forest microbial biodiversity.

Outcome Measures

Primary Outcomes (1)

  • Transepidermal water loss (TEWL)

    TEWL measurement from each test area (arms)

    0, 14 and 28 days

Secondary Outcomes (5)

  • Skin erythema index

    0, 14 and 28 days

  • SCORAD (SCORing Atopic Dermatitis)

    0 and 28 days

  • Local scoring of eczema on arms

Study Arms (2)

Nature-based exposure by biodiversity component in lotion.

ACTIVE COMPARATOR

Biodiversity component is highly diverse microbial extract mimicking Finnish forest soil biodiversity. Component is added to the common moisturizer on the Finnish market.

Other: Biodiversity intervention by inactivated microbial extract

Placebo by coloring component in lotion.

PLACEBO COMPARATOR

Coloring ingredient is safe, biochemically non-active component which purpose is to make the placebo lotion looking same as the biodiversity lotion in other arm. Component is added to the common moisturizer on the Finnish market (same as in the other arm).

Other: Placebo intervention by colored lotion

Interventions

Participants use the lotion including microbial extract on one arm twice a day for 28 days. No other lotions or creams are used simultaneously on this area. Atopy medicines are not used during the trial or 14 days before the trial.
