🔬TODAY’S BREAKTHROUGH
A new human clinical study reveals that pterostilbene, a natural molecule found in blueberries, can significantly improve visible signs of skin aging in just 28 days, pointing to a new direction in cosmetic science.
The Discovery:
In a 28-day double-blind, split-face trial involving 31 participants, Chinese researchers tested a skincare emulsion containing 0.1% pterostilbene against a control. The pterostilbene formulation remarkably improved skin firmness, elasticity, and reduced wrinkles (forehead, undereye, crow's feet) while also increasing epidermis thickness and enhancing collagen and elastic fibers.
The Science:
Pterostilbene is a natural antioxidant found in blueberries, structurally similar to resveratrol.
The double-blind, split-face design (pterostilbene on one side, placebo on the other) ensured unbiased results.
Significant improvements were observed in skin elasticity, firmness, and wrinkle reduction.
It also increased epidermis thickness, a marker of youthful skin, and boosted collagen and elastic fibers.
Subjects reported higher satisfaction with the pterostilbene emulsion compared to the control.
The study suggests multiple mechanisms for its anti-aging efficacy in skin.
Your Action:
Consider looking for skincare products containing pterostilbene if you're interested in topical anti-aging. As a natural antioxidant, it aligns with broader health goals. Remember that topical application differs from oral supplementation, and consistent use is key for visible results.
Bottom Line:
Pterostilbene offers a potent, natural solution for visibly reversing skin aging signs in humans, opening new avenues for science-backed skincare.
