Short-term clinical of peel-off facial mask moisturizers

Synopsis Objective This study aimed to compare the efficacy of a peel‐off facial mask based on polyvinyl alcohol (PVA) with an oil‐in‐water (o/w) emulsion and the effect of a soybean extract fermented by Bifidobacterium animale incorporated in those formulations (5% w/w). Methods The formulations we...

Description
Summary:Synopsis Objective This study aimed to compare the efficacy of a peel‐off facial mask based on polyvinyl alcohol (PVA) with an oil‐in‐water (o/w) emulsion and the effect of a soybean extract fermented by Bifidobacterium animale incorporated in those formulations (5% w/w). Methods The formulations were submitted to randomized clinical studies in volunteers to evaluate the measurement effects as (a) tensor by Cutometer®, (b) moisturizing by Corneometer® and transepidermal water loss (TEWL) by Tewameter®. These effects were determined in a short‐term study (3 h) in a controlled‐temperature room. Results The tensor effect and TEWL values indicated no significant difference between the use of facial mask and emulsion. On the other hand, the moisturizing effect of the facial mask on the stratum corneum was more significant than that of the emulsion according to Corneometer® measurements. Biometric cutaneous evaluation of peel‐off facial masks (short‐term study) showed that the masks promoted moisturizing effect of the stratum corneum more effectively than the oil‐in‐water emulsions. Thus, the facial masks were more efficient than emulsions in relation to moisturizing effects, but this efficiency is not related to the presence of fermented soybean extract. Conclusion The results indicated that peel‐off facial masks increase skin hydration in a process related to the occlusive effect. Résumé Objectif Cette étude avait pour but de comparer l'efficacité d' un masque facial détachable à base d'alcool polyvinylique (PVA) avec une émulsion huile‐dans‐eau (H/E) et d'observer l'effet d'un extrait de soja fermenté par Bifidobacterium animale incorporé dans ces formulations (5% p/p). Methodes Les formulations ont été soumises à des études cliniques randomisées chez des volontaires pour évaluer les effets tels que : (a) tenseur par Cutometer®, (b) l'hydratation par Corneometer® et la perte insensible en eau (PIE) par Tewameter®. Ces effets ont été déterminés dans une étude à court terme (trois heures) dans une chambre à température contrôlée. Resultats L' effet tenseur et les valeurs de PIE n'ont révélé aucune différence significative entre l'utilisation d' un masque facial ou de l'émulsion. D'autre part, l'effet hydratant du masque facial sur le stratum corneum était plus important que celui de l'émulsion selon les mesures au Corneometer®. L'évaluation cutanée biométrique de masques de visage détachables (étude à court terme) a montré que les masques augmentent l'effet hyd
