Recent research from the George Washington School of Medicine suggests that cannabidiol (CBD), a compound derived from the cannabis plant, may offer protective benefits against UVA radiation, which is known to cause skin aging and increase cancer risk.
Key findings from the study
- UVA protection: CBD may help shield the skin from harmful UVA rays.
- Clinical trial: A small study involving 19 participants showed that skin treated with CBD cream exhibited less redness after exposure to UV radiation.
- Complementary use: Experts emphasize that CBD should not replace sunscreen but could be used alongside it for enhanced protection.
Study overview
The study involved participants with Fitzpatrick skin types I-III and required them to apply two different creams on their buttocks: one containing nano-encapsulated CBD and the other without. After two weeks, their skin was exposed to high levels of UV radiation.
Results showed that 21% of participants had reduced redness on the CBD-treated side compared to the control. Additionally, skin thickening and DNA damage due to UV exposure were significantly lower in the CBD-treated samples.
Expert opinions
Dr. Adam Friedman, a co-author of the study, noted the importance of exploring all options for skin protection against UV radiation. He stated, “This study highlights that a nano-CBD formulation could be an additional weapon against the harmful effects in combination with our current modalities.” However, he cautioned that more research is needed to validate these findings.
Dr. Sherry Yafai, an emergency medicine physician, echoed this sentiment, emphasizing that while the results are promising, the effectiveness of CBD needs further investigation. She pointed out that the current effectiveness rate of 21% is not sufficient for medical standards.
The future of sun protection
Experts believe this research could pave the way for innovative sun protection options. Dr. Zakia Rahman highlighted the growing recognition of the medical benefits of non-psychotropic cannabinoids, stating, “This research is promising and could lead to more products that protect against UVA damage.”
Understanding CBD
CBD is distinct from THC, the psychoactive component of cannabis, and is often used for various health purposes, including pain relief and anxiety management. Despite its potential benefits, CBD still faces stigma in the medical community, which experts like Dr. Yafai are working to change.
While the GWU study indicates that CBD may have a role in protecting the skin from sun damage, it is crucial to remember that it should not replace traditional sunscreen. As research continues, CBD could become a valuable addition to our sun protection arsenal.
