Brief Summary

The aim of this prospective, uncontrolled clinical study is to evaluate the clinical effect of Ectoin® Dermatitis Cream-EHK02 on skin hydration and transepidermal water loss (TEWL) in subjects with atopic dermatitis after single and multiple applications. Furthermore, data concerning the subjective impression of the study preparation should be collected.

Conditions

Atopic Dermatitis Eczema

Keywords

Ectoin; Ectoin Dermatitis Cream; Atopic dermatitis

Outcome Measures

Primary Outcomes (2)

• Change from baseline in mean corneometer measurement 8 hours after treatment

  Corneometer is a non-invasive instrument that measures barrier function of the skin surface. Change of skin hydration will be assessed comparing values before (initial condition-pretreatment) and after single application. The electrical capacitance of the skin surface will be expressed digitally in arbitrary units. Three measurements will be performed on each test area and the mean will be used to define the skin barrier function of the stratum corneum.

  baseline (pretreatment), 8 hours after first application (post treatment)

• Change from baseline in mean tewameter measurement 8 hours after treatment

  Transepidermal water loss (TEWL) is affected by environmental factors as humidity, temperature, the time of year (seasonal variation) and the moisture content of the skin (hydration level). Tewameter is a non-invasive instrument that measures skin hydration. Change of skin hydration will be assessed comparing values before (initial condition-pretreatment) and after single application. The TEWL measurement will be measured three times and the mean than will be used to define skin hydration of the stratum corneum. The hydration of the skin surface will be expressed in g/hm².

  baseline (pretreatment), 8 hours after first application (post treatment)

Secondary Outcomes (4)

• Change in skin hydration over time (1, 8, and 24 hours) after single application compared to initial condition (pretreatment).

  baseline (pretreatment), 1 hour, 8 hours and 24 hours after first application (post treatment).

• Change in skin barrier function over time (1, 8, and 24 h) after single application compared to initial condition (pretreatment).

  baseline (pretreatment), 1 hour, 8 hours and 24 hours after first application (post treatment).

• Change from baseline (initial condition) in mean Tewameter measurement 7 days after treatment.

  baseline and 7 days after treatment

• Change from baseline (initial condition) in mean Corneometer measurement 7 days after treatment.
