Methodological Study of the Effect of a Lotion Containing Nature Based Microbial Extract on Atopic Skin

Overview

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.

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.
