Cannabidiol's Antioxidant Properties in Skin Care Products and Legislative Regulations

Cannabidiol (CBD) has garnered interest in its potential antioxidant properties in skin care. This review synthesizes the current literature exploring CBD's role as an antioxidant and anti-inflammatory cosmetic ingredient and its impact on skin health. CBD exhibits antioxidant effects by scavenging free radicals, reducing oxidative stress, and mitigating inflammation, all of which contribute to aging and skin conditions like acne and dermatitis. CBD interacts with the endocannabinoid system and other cellular pathways to bolster antioxidant defenses in skin cells. The search engines were Google Scholar, Scopus, and PubMed. The search was performed using the main keywords "liposomal CBD and keratinocytes", "antioxidant properties of CBD and keratinocytes", "anti-inflammatory activity of CBD and keratinocytes", "CBD and cosmetics", "CBD and skin care products", and "CBD and cosmetic products regulation" for the period 2018-2025. The period for the search of the literature was chosen based on the legalization of medical cannabis. Its non-psychoactive nature and favorable safety profile make CBD a compelling candidate for inclusion in skin care formulations seeking natural and effective antioxidant solutions. As consumer demand for botanical-based skin care rises, CBD stands out for its promising therapeutic benefits and potential applications in anti-aging and dermatological treatments. Despite its benefits, using CBD in cosmetics is not without its challenges. The varying legal status of CBD in various jurisdictions is confusing to both the cosmetic industry and consumers. Some jurisdictions allow CBD to be derived from hemp, while others may prohibit its use. The legal and regulatory status of CBD is a constantly changing matter. The purpose of the article is to review the liposomal forms of encapsulated CBD to increase its percutaneous absorption and therefore its antioxidant, anti-inflammatory effect on keratinocytes. Liposomal CBD firstly bypasses the problems of insolubility of free radicals and secondly protects it from various exogenous oxidizing agents, while maintaining its activity. CBD is a valuable antioxidant agent in skin care science, suggesting avenues for further research and product development.
