Two new studies have recently been published 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 the body of science into pTeroWhite’s value as a cosmeceutical ingredient for anti-aging, skin brightening, and as a natural SPF agent.
An Open-Label Single-Arm, Monocentric Study Assessing the Efficacy and Safety of Natural Pterostilbene (Pterocarpus marsupium) for Skin Brightening and Antiaging Effects1, published in Clinical, Cosmetic and Investigational Dermatology, was conducted as an open-label, single-arm, monocentric efficacy investigation in 38 healthy volunteers who applied a cream containing 0.4% pterostilbene for eight weeks. The dermatological assessment, together with instrumental and image analysis, suggests that pterostilbene effectively improves skin brightness, elasticity, reduces the appearance of fine lines, wrinkles, and improves 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. They found significant improvement in under-eye fine lines at all-time points and in wrinkles, frown lines, and crow’s feet area at the end of the study. The pterostilbene preparation was able to improve the skin luminosity with continuous application.
