Methodological Study of the Effect of a Lotion Containing Nature Based Microbial Extract on Atopic Skin
- Conditions
- Atopic Dermatitis
- Interventions
- Other: Biodiversity intervention by inactivated microbial extractOther: Placebo intervention by colored lotion
- Registration Number
- NCT06499766
- Lead Sponsor
- Uute Scientific Oy
- 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.
- Detailed Description
According of hygiene and biodiversity hypotheses, regular contact to nature biodiversity is beneficial for human health. Without the contact, there is risk for immune system malfunction and related diseases like atopy, allergies and inflamed bowel diseases. Regular contact to natural biodiversity, including environmental microbes, add immunological tolerance and train immune system to separate dangerous external stimuli from non-dangerous ones.
This study aim at testing if it is safe to use microbial extract in lotion on daily basis on atopic skin. Study participants are adults and they have atopic dermatitis diagnosis. Participants use the lotion with microbial extract on other arm and placebo lotion (same lotion but microbial extract is replaced with safe coloring ingredient) on the other arm two times per day for 28 days. Atopy medicines are not used on the study period and 14 days before the study. Also, other moisturizers than test lotions are not used on test areas during the study.
Study is placebo controlled, randomized and double-blinded.

Group Intervention Description Nature-based exposure by biodiversity component in lotion. Biodiversity intervention by inactivated microbial extract Biodiversity component is highly diverse microbial extract mimicking Finnish forest soil biodiversity. Component is added to the common moisturizer on the Finnish market. Placebo by coloring component in lotion. Placebo intervention by colored lotion 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).
