New Study About Nano-CBD and UVA Radiation
The George Washington University Schools of Medicine and Health Science and the Center for Clinical and Cosmetic Research in Florida conducted a study in which 19 participants applied nano-CBD to their bodies. The skin areas were exposed to ultraviolet light the next day and examined for sun damage symptoms. Biopsies were then taken for analysis.
The clinical trial had some participants apply a nano-encapsulated CBD cream, and the rest applied the same cream without CBD. The cream was applied twice daily for 14 days. At the end of the 14 days, the treated skin was exposed to ultraviolet radiation in an amount three times that needed to injure or burn the skin. Twenty-four hours after the radiation exposure, skin biopsies were taken for analysis. The purpose was to determine the amount of cellular and DNA damage from exposure to ultraviolet radiation.
The analysis of the skin biopsies yielded several encouraging findings. Notably, the participants using CBD cream showed significant improvement compared to those using the non-CBD cream.
- 21% showed less redness on the CBD-treated skin
- Skin thickening of the skin biopsies was significantly reduced
- Skin biopsies had reduced DNA damage and DNA mutations
“This innovative trial is the first to establish the potential protective capacity of CBD when purposefully delivered, in humans against the harmful effects of UVA radiation, both validating and marking a significant advancement in the field of cannabinoid-based skin care,” said Adam Friedman, professor and chair of dermatology at the GW School of Medicine and Health Sciences.
Nano CBD is a type of cannabidiol that uses nanotechnology to encapsulate or coat the CBD molecules with stabilizers like lipid nanoparticles or liposomes. The process is called nano-emulsion. The stabilizer makes CBD more soluble, allowing it to be absorbed faster.
This is still a nascent study area, so more research is needed. However, if nano CBD may help prevent sun damage to skin cells, what other benefits could it provide users? “These findings will hopefully reinvigorate research efforts and investment in translating the preclinical knowledge we have on the impact of CBD in the skin to many areas within dermatology and beyond,” Friedman said.
Clinical studies involving CBD continue to show that CBD potentially has numerous health and wellness uses.
