Two recently published studies found that a natural pterostilbene (pTeroWhite from Sabinsa Corp.; East Windsor, NJ), isolated and purified from Pterocarpus marsupium heartwood and formulated as a cream, may provide anti-aging, skin brightening, and natural SPF protection. In the first study, an open-label, single-arm, monocentric efficacy investigation published in Clinical, Cosmetic and Investigational Dermatology, 38 healthy volunteers applied the cream containing 0.4% pterostilbene for eight weeks.

Compared to baseline, dermatological assessment, together with instrumental and image analysis, suggested that pterostilbene effectively improved skin brightness, elasticity, reduced the appearance of fine lines, wrinkles, and improved skin texture. Subjects also saw significant improvements in under-eye fine lines at all time points, as well as in wrinkles, frown lines, and crow’s feet at the end of the study. The second study published in the journal Cosmetics demonstrated that the ingredient has an SPF value both in vivo and in vitro, concluding that it would be a safe ingredient in topical sun protective formulations.

“We’ve long thought that natural pterostilbene had tremendous potential in cosmeceutical applications, which is why we began conducting research,” said Sabinsa’s founder and chairman Muhammed Majeed, PhD. “Investigations are continuing to further expand our knowledge to support new product applications.”
