Abstract
Objective: A temperature-sensitive state-changing hydrogel mask was used in this study. Once it comes into contact with the skin and reaches the body temperature, it uniformly and quickly releases the active compounds, which possess moisturizing, anti-oxidant, anti-inflammatory and regenerative properties. Methods: An open label clinical trial was conducted to evaluate the effects of the test product on skin hydration, skin tone and skin ageing. Subjects applied the product to one side of their face and underwent Corneometer® and Chromameter measurements, Visual assessment of facial skin ageing and facial photography. All assessments and Self-Perception Questionnaires (SPQ) were performed at baseline, after the first application of the test product and after four applications. Results: After a single treatment we observed an increase in skin moisturisation, an improvement of skin tone/luminosity and a reduction in signs of ageing, all statistically significant. After four applications a further improvement in all measured parameters was recorded. These results were confirmed by the subjects’ own perceptions, as reported in the SPQ both after one and four applications. Conclusion: The hydrogel mask tested in this study is very effective in improving skin hydration, skin radiance and luminosity, in encouraging an even skin tone and in reducing skin pigmentation.
Highlights
IntroductionPlays a major role in maintaining homeostasis and environmental protection
The skin is the largest organ of the human body, it accounts for about 16% of its total weight [1]and plays a major role in maintaining homeostasis and environmental protection
Free water is able to diffuse from the skin to the outer environment, while bound water is associated with many other molecules, so-called “Natural Moisturizing Factors” [3]
Summary
Plays a major role in maintaining homeostasis and environmental protection. It regulates the body temperature and the body fluid content, and represents the principal barrier to the external environment, for example, it protects against pathogenic agents and UV radiations [2]. The water in the skin can be present in the form of free or bound water molecules. Free water is able to diffuse from the skin to the outer environment, while bound water is associated with many other molecules, so-called “Natural Moisturizing Factors” [3]. Reduced moisture will lead to loss of skin radiance and skin elasticity. The reduction in elasticity decreases skin’s ability to retain its shape and this causes the formation of fine lines and wrinkles
