Periodical observation of freckles (number and area) and wrinkles in eye angle (length and area) was conducted with Robo Skin Analyzer.*
Subjects: 17 women between 26 and 60 years old
As a result it was possible to observe an improving tendency in the subjects'' skin condition. Considering a 10% or higher reduction of pigmentary deposit area as a improvement tendency, there was an improvement in 29% of the cases (5 subjects out of 17). Considering a 10% or higher reduction of the wrinkle area as improving tendency, there was improvement in 47% of cases (8 subjects out of 17). Results were more visible in participants over 40 years old.
UV Protection Effect
Exposure to the sun''s ultraviolet (UV) light generates reactive oxygen species (ROS) that induce activation of tyrosinase that triggers generation of melanin, and production of the pigment that gives color to skin. Freckles are accumulations of melanin that is produced by melanocytes. Active oxygen also induces damage of collagen and elastin cross link in the mid-dermal layer reducing the tension between cells and consequently producing wrinkles.
Results of the studies have been presented at symposiums and scientific journals around the world.
