Skin's "Tipping Point" Identified by P&G Researchers

P&G beauty and grooming scientists have identified the “skin tipping point”of skin aging and suggested topical ingredients that may slow down this tipping point. At the 69th Annual Meeting of the Society for Investigative Dermatology in Montreal on May 6–9, 2009, scientists from the company presented research that offers important insight on the skin aging process.

Findings from a recent clinical trial indicate a relatively sudden change in the appearance of skin as it ages, identified as the skin tipping point. A follow-up study conducted to evaluate the efficacy of topical ingredients in delaying the skin tipping point demonstrated significant improvement in skin’s elasticity.

To investigate the skin aging process, the scientists used a multi-layered skin elasticity model to evaluate sudden change in skin appearance. Findings suggested that loss of elasticity causes the skin tipping point, resulting in a sudden visible increase in noticeability of fine lines, wrinkles and sagging.

In the study presented, researchers assessed the validity of the skin tipping point by conducting a clinical trial of 102 healthy, Asian females aged 25 to 55. The scientists compressed the subjects’ skin to varying degrees with a newly developed skin compression imaging system in order to analyze the subsequent skin deformation, or wrinkling. The study found an abrupt change in noticeability of skin wrinkling among subjects in their 30s, with significant differences in wrinkling observed between ages 20 and 30, and 30 and 40.
