Sea Buckthorn seed oil shows skin nourishing potential
Seed oil from Sea Buckthorn extracted by supercritical CO2 extraction may improve skin hydration, says a new study from Pigeon.
In vitro data indicated that supercritical CO2 extracted, Omega-rich extract of Sea Buckthorn (Puredia SeaBerry® Seed Oil) up-regulated Hyaluronic Acid Synthetases 2 (HAS2) and Aquaporins 3 (AQP3) protein expression in reconstructed epidermis skin model, improving skin hydration.
HAS2 expression boosts the synthesis of hyaluronic acid, which is responsible for facilitating skin hydration and further influencing inflammation, cell proliferation, and wound healing. AQP3 expression causes more water to be transported from the dermis to the epidermis, which maintains skin hydration.
“We proved for the first time that Sea Buckthorn seed oil can improve skin hydration through increasing AQP3 and HAS2 expressions, which indicates it is a promising natural compound to boost the skin's ability to retain moisture,” wrote researchers from Pigeon Manufacturing in Journal of Cosmetic Dermatology.
This study complies with the results from a human clinical trial done on 60 women with oral or topical application of sea buckthorn oil. After 3 months of treatment, the skin hydration was increased by 49% in the oral supplementation group and 31% in the topical application group (P<0.001). Moreover, significant improvements were also observed on overall skin elasticity, skin surface roughness, and skin cutaneous thickness, indicating the anti-wrinkle efficacy of sea buckthorn oil. These results suggest that Omega-rich Sea Buckthorn oil led to improvements in collagen synthesis and positive structural changes in the skin.
