Overview
This exploratory study aims to verify the impact on the severity of eczema as well as the prebiotic potential of a daily application of Omega-3 serum and cream on a skin with eczema. This study will also collect data on possible adverse effects of the products. Sixteen participants will be enrolled in this study and will be divided in two groups of 8 subjects that will receive two different treatments for forty-two days. The baseline condition will serve as a control for the effects observed after treatment on the targeted eczema area.
Description
Omega-3 fatty acids and more particularly EPA are recognized as fatty acids promoting the resolution of inflammation unlike omega-6 fatty acids, which are pro-inflammatory. The skin, which is the largest organ of the human body, receives a greater proportion of omega-6 fatty acids because skin care products are mostly made of omega-6-rich vegetable oil. This imbalance could be one of the causes of inflammatory skin diseases such as eczema. Conventional omega-3 need to pass through the digestive tract to be activated in the form of monoglycerides. Hence, it is not relevant to use them for a topical formulation. However, the recent development of pre-activated omega-3 monoglycerides finally opens the possibility of introducing active omega-3 fatty acids into moisturizing products.
Subjects of group A will receive treatment A coinsisting of serum A and cream A. Subjects of group B will receive treatment B coinsisting of serum B and cream B. A skin area with eczema lesions will be identified during the screening visit. Subjects will be asked to apply the provided serum and cream to the clean targeted area at least once a day, every day, for a period of forty-two (42) days. The pre-treatment baseline state will serve as a control for the effects observed following treatment on the targeted area.
The targeted eczema area will be used to measure the main parameters of the study:
- Quantify by qPCR the four main bacteria of the skin microbiota (Staphylococcus aureus, Staphylococcus epidermis, Cutibacterium acnes and Streptococcus pyogenes). Specimens will be collected before the start of treatment (visit 1) as well as after three weeks (visit 2) and six weeks of treatment (visit 3).
- Compare the evolution of eczema lesions pre and post treatment by administering a self-assessment questionnaire for eczema severity (POEM). The POEM questionnaire will be administered before the start of treatment (visit 1) as well as after three weeks (visit
- and six weeks of treatment (visit 3).
This study will also aim to collect data on the possible undesired effects of the products.
