Sabinsa has published two new studies on the topical benefits of Sabinsa’s pTeroWhite® natural pterostilbene isolated and purified from Pterocarpus marsupium heartwood and formulated as a cream. The studies further reveal pTeroWhite’s value as a cosmeceutical ingredient for anti-aging, skin brightening, and as natural SPF agent.
Pterostilbene Improves Skin Brightness
The study was conducted on 38 healthy volunteers who applied a cream containing 0.4 percent pterostilbene for eight weeks. The results suggested that pterostilbene improves skin brightness, elasticity, reduces the appearance of fine lines, wrinkles and improve skin texture as compared to baseline in the subjects studied.
The researchers observed a positive change at all time points in skin hydration and elasticity in both male and female subjects with regular usage of the pTeroWhite cream. The pterostilbene preparation was able to improve the skin luminosity with continuous application.
All the subjects agreed that the test product made their skin appear moisturized, brighter, younger, firmer, and even toned. Further, researchers observed no product-related skin irritation, intolerance, or adverse events during the study. The report concluded that the application of pterostilbene cream twice daily for eight weeks was safe and improved skin texture and tone.
Effect of pTeroWhite as Natural SPF Agent
A second clinical study was performed to demonstrate the effect of pTeroWhite as a natural SPF ingredient. A cream formulation, containing 0.4 percent of pTeroWhite, was evaluated in 12 healthy volunteers as per the ISO 24444:2010 regulations and showed an in vivo SPF value of 6.2 ± 1.30. The cream was found to be safe and non-irritant in a repeated patch test conducted in 25 healthy individuals before the SPF study.
The cream showed an SPF of 8.84 ± 0.01
in vitro, while pTeroWhite as an ingredient had an SPF value of 21.73 ± 0.06. The study concluded that pTeroWhite could be a safe ingredient in topical sun-protective formulations.
“
We have long thought that natural pterostilbene had tremendous potential in cosmeceutical applications, which is why we began conducting research. Investigations are continuing to further expand our knowledge to support new product applications,” said Sabinsa founder and chairman, Dr. Muhammed Majeed.
