Skin care ingredients derived from blueberries show impressive results in anti-wrinkle and improving skin elasticity, according to a new clinical study that has led natural compounds to contradict control formulas in head-to-head testing.
The 28-day trial examined pterosaurs, a polyphenol compound found naturally in blueberries, grapes and certain trees. Thirty-one participants applied 0.1% pterosaur emulsion to one side of their face and the other side to the control base, resulting in a controlled comparison, and found significant differences in the anti-aging effect.
Measurable improvements to multiple skin indicators
Wingspan processing has been substantially improved on almost every measured parameter. Four weeks later, skin elasticity increased by 32.6%, while firmness increased by 7.3%. Perhaps most notably, the area of the forehead wrinkle dropped by 13.9% and the volume dropped by 15.4%.
The wrinkles at the moment also react well, with a 7% reduction in area and a nearly 6% reduction in volume. Even the infamous stubborn crow’s feet showed improvement, with the percentage of wrinkles falling by 13.6%.
The study uses sophisticated imaging techniques to measure these changes, including a 3D skin analysis system and a two-photon microscope, which can visualize collagen and elastin fibers at the cellular level.
Cellular changes support surface results
In addition to surface improvement, pterosaur treatment also triggers beneficial changes in skin structure. The epidermal thickness increased by 8.3%, while collagen strength increased by nearly 20%. Most significantly, the elastic fiber fluorescence intensity jumped by 77%, indicating that these crucial skin support proteins regeneration significantly.
“Our results indicated that the pterostilbene emulsion remarkably improved skin elasticity, firmness, and reduced wrinkles, such as forehead, underreye, and Crow’s feet wrinkles,” shares co-author Zhiyuan Chen, Founder of Guangzhou Luanying Cosmetics Co., Ltd. The treatment also “increased the thickness of the epidermis layer, enhanced collagen and elastic fiber.”
Participants overwhelmed the pterosaur treatment and reported higher satisfaction scores for all measurement categories, including moisture, smoothness, and overall skin appearance.
Natural alternatives to resveratrol show commitment
Pterosaurs represent the evolution of resveratrol, a well-known antioxidant found in red wine. Although both compounds belong to the Stilbenoid family, Pterostilbene offers several advantages for skin care applications. The molecule exhibits greater stability, higher bioavailability and less stimulation potential than its more famous cousin.
Stability factors are particularly important for cosmetic formulations where the active ingredients must remain effective throughout the product’s shelf life and daily use.
Key benefits observed in the study:
- 32.6% improvement in skin elasticity within 28 days
- 13.9% reduction in forehead wrinkle areas
- Elastic fiber regeneration increased by 77%
- Compared with the control, a large number of pore sizes are refined
- Enhanced epidermal thickness and collagen production
Science and rigorous strengthen the discovery
Research design combines several elements that can enhance its credibility. The double-blind, split approach is by having participants apply different treatments on each side of the face without knowing which one is which one. A variety of measurement techniques provide objective data to complement subjective assessments.
According to corresponding author Xueping Chen, the finding improves understanding of the role of Pterostilbene in skin care by providing evidence of its effective anti-aging effects. “It also provides new perspectives on the application of natural compounds in the skin care industry,” Chen noted. “The significant improvements in various skin parameters and positive feedback from subjects highlight the effectiveness of pentobene, which may change the way we approach the anti-aging skin care formula.”
The study, published in the Journal of Dermatology Science and Cosmetics Technology, adds scientific evidence to support natural skin care compounds. Although the cosmetics industry has long sold plant ingredients, rigorous clinical testing of specific compounds remains relatively rare.
The study authors acknowledged limitations, including relatively short durations and focused on Chinese participants aged 32-53. They recommend long-term research to fully understand the impact of wing status and recommend testing of different populations to confirm broader applicability.
For consumers interested in pterostilbene-based products, this study provides reliable scientific support for anti-aging propositions. However, the specific 0.1% concentration used in this study may not reflect the formulations currently available in commercial products.
