The Effect of Isosorbide Diesters Based Moisturizer on Skin Health

Study Overview
=================
Brief Summary
-----------------
The overall objective of this study is to assess how a natural ingredient, isosorbide diesters (IDEAS), works in association with colloidal oatmeal for eczema.

Detailed Description
-----------------
The topical therapy of eczema largely focuses on the use of topical medications but there is demand for topical moisturizers and ingredients that can reduce the need for topical steroids. The goal of this study is to assess the use of a natural ingredient, isosorbide diesters (IDEAS), for eczema and if it can reduce the need for the use of topical steroids.

Eligibility Criteria
-----------------
Inclusion Criteria: Men and women aged 18 or over Subjects with a diagnosis of mild to moderate eczema with a SCORAD between 1-50. Exclusion Criteria: Individuals who have a known allergy to isosorbide diesters. Individuals who have solely hand and/or foot eczema without evidence of eczema anywhere else on their body. Individuals who have been on topical calcineurin inhibitors or crisaborole to the predetermined areas within two weeks of initiation of participation or unwilling to undergo a washout period. Subjects with an ongoing secondary infection of the skin. Subjects who are on systemic therapy or who need systemic therapy at the discretion of the investigator.
