A new study published in the peer-reviewed journal Carbohydrate Polymers found that a cannabidiol-infused injectable hydrogel may offer a stronger, longer-lasting approach to facial fillers by combining physical support with antioxidant effects.
Researchers from Beijing Forestry University developed a composite hydrogel made from carboxymethyl cellulose (CMC), cellulose nanofiber (CNF) and cannabidiol (CBD)-loaded polycaprolactone microspheres. The material was designed to address two common limitations of current fillers: weak mechanical support and the inability to target oxidative stress, a key factor in skin aging.
According to the study, adding a small amount of CNF to the CMC gel created a stronger hydrogen-bonding network and physical entanglements, increasing mechanical strength by 3.7-fold. Researchers said the CBD-loaded microspheres also provided sustained antioxidant activity, with testing showing notable reactive oxygen species scavenging.
The hydrogel also showed strong biocompatibility. In rat studies, subcutaneous injections produced a durable volumizing effect and promoted collagen synthesis, suggesting it could support both physical filling and skin rejuvenation.
Researchers said the CMC/CNF/CP hydrogel offers “superior mechanical properties and sustained antioxidant properties,” making it a promising candidate for next-generation facial fillers.
The findings add to a growing body of research exploring CBD’s potential uses in skin health and biomedical materials, particularly due to its antioxidant properties and ability to be incorporated into controlled-release delivery systems.
