Anti-Inflammatory Efficacy of Product Containing “Skin Calm Complex” in Vitro Reconstructed Epidermis

Abstract

Atopic dermatitis is classified as a chronic inflammatory skin disease, which is characterized by alterations in barrier function and immune system of the skin. In a previous study, the efficacy of REPAVAR ATOPIC SKIN BODY CREAM EXTREME (a product containing “SKIN CALM COMPLEX”) on the epidermal barrier structure was demonstrated. However, the product has also been formulated to improve inflammation and itching. The aim of this study is to analyze product effectiveness on skin inflammation and itching which is associated with atopic dermatitis, by quantification of IL-1α and IL-8 interleukins secreted by human keratinocytes from reconstructed epidermis by ELISA assay. Mature (aged 17 days) sample tissues were treated with pro-inflammatory agents (PBS 1X and LPS) and with the product containing synergistic mix from plants extracts and Dihydroavenanthramide D, among other ingredients (“SKIN CALM COMPLEX”) for 24 hours.
