Yes, a third party independent at Soiken, Japan's Institute of General Medical Sciences, performed a related study. The study consisted of 33 individuals (6 male, 27 female, with an average age of 25), being given a placebo or 40 mg of ceramides by Oryza each day, over the course of 6 weeks.
Dermatologists were brought in to perform three-dimensional, microscopic skin surface analyses, performed using VISIOCAN, and conducted by Courage and Khaza Gmbh. This was able to evaluate the skin for moisture content, smoothness, and more.
This study concluded that Oryza Ceramide-PCD—an ingredient in La Muse PhytoCera—increases skin hydration, minimizes small lines and wrinkles, promotes skin smoothness and fights signs of aging visibly and from within.
The moisturizing effects of Oryza Ceramide have been studied with other commercially available ceramides. Oryza Ceramides were evidenced to be among the best, with a moisture ratio of over 35 percent.
