An innovative ecobiological wound repair cream that restores the microbiome

Small everyday wounds would benefit from optimal healing conditions, and the role of the microbiome in this process is being increasingly discussed. Objectives: To evaluate a wound repair cream (Cicabio Crème+, NAOS Ecobiology Company, Bioderma, France), assessing its effects on the skin microbiome and wound healing. The impact on the microbiome was evaluated by monitoring restoration of diversity after disinfection. The efficacy of the repair complex was assessed ex vivo using a 3D wound-healing human skin model to analyse closure and protein expression. Short-term evaluation of adherence, gas permeability, wound protection, and hydration was assessed. In vivo efficacy was examined through two clinical studies: one on healing erosive areas and another after chemical peel. After disinfection, the cream accelerated restoration of microbiome diversity (+31%, p=0.001) without promoting pathogenic/commensal bacteria or altering the level of Staphylococcus epidermidis (p=0.193). In a 3D wound-healing model, the repair complex enhanced wound closure, promoting protein expression (Ki67, loricrin, CD44, collagen XVII, VII, III) and re-epithelialisation. The cream adhered to the skin, allowed gas exchange, and provided protection and hydration. In vivo, the cream reduced transepidermal water loss (day 4: p=0.016; day 7: p=0.014), erythema (day 7: p=0.023), and functional signs (day 4: p=0.032) of erosive wounds. Following chemical peels, the cream reduced inflammation (day 7: p=0.037), visible damage (day 7: p=0.029), and skin pH (day 1: p<0.001). We demonstrate, for the first time, protection of microbiome diversity, stimulation of wound closure, and preservation of skin pH using a wound repair cream.
