Researchers then conducted a second clinical trial to evaluate the efficacy of hydrating topical antiaging ingredients in improving skin elasticity. The trial, conducted over an eight-week period in 72 healthy, Japanese females age 35 to 55, showed significant improvement in skin elasticity with the topical application of 0.1% olive oil-derived fatty acids modified with PEG-7, 5% niacinamide and yeast ferment filtrate.
Analyses of the data indicate application of these ingredients delays the skin tipping point between three to four years. “While it is often assumed that skin ages gradually, our research explored this new skin elastic tipping point model, which prior to this time has not been examined in clinical studies,” said lead study author Kukizo Miyamoto, PhD, R&D for beauty and grooming at Procter & Gamble Japan in a company press release. “These clinical study findings confirm sudden changes in skin appearance demonstrated by simulation with the multi-layered skin elasticity model. Furthermore, our research provides critical insight into topical ingredients that are driving new research directions and that will impact future product formulations.”
