In the U.S., any product marketed as sunscreen is considered an over-the-counter (OTC) drug. Its UV protection must come from FDA-permitted active ingredients such as zinc oxide, titanium dioxide, or select organic filters. These approved actives must undergo SPF and Broad Spectrum testing and appear in a Drug Facts panel. Cannabinoids like CBD or THC are not recognized UV filters, meaning that when they appear in sunscreen, they serve only as inactive, supportive ingredients alongside the true sun-blocking agents. Simply put, cannabinoids cannot replace zinc oxide or avobenzone, and any SPF rating reflects the full formula’s performance, not the cannabinoid content.
The term “marijuana-infused” typically refers to the addition of cannabis-derived ingredients—most often cannabidiol (CBD) extracted from hemp—to a sunscreen formulation. This is not the same as using hemp seed oil, which is produced by pressing hemp seeds and contains little to no cannabinoids. While hemp seed oil offers moisturizing and emollient benefits, it does not provide the anti-inflammatory or antioxidant properties associated with cannabinoids. Therefore, a product made only with hemp seed oil is not truly “CBD-infused,” even though it may be marketed with cannabis imagery.
CBD’s inclusion in sunscreen is largely based on its antioxidant and skin-calming potential. Early research indicates that CBD can help neutralize free radicals, reduce redness, and support the skin’s natural barrier. These benefits may complement UV filters by minimizing oxidative stress caused by sun exposure, but they do not contribute to the sunscreen’s SPF value. In essence, CBD’s role is supportive—enhancing post-sun comfort and overall skin wellness rather than delivering protection against UV rays.
Regulation remains a critical factor. The FDA has not approved CBD as an active sunscreen ingredient, and its safety profile within cosmetics continues to be evaluated. Brands that incorporate cannabinoids into sun care products must still comply with all OTC sunscreen regulations, including SPF testing and accurate labeling. Adding CBD does not exempt a product from these rules. Furthermore, companies are prohibited from making medical or therapeutic claims about CBD in sunscreen, such as “heals sunburn” or “prevents skin cancer.”
Consumers can make more informed choices by reading labels carefully. Look for sunscreens that clearly list their active ingredients and include “Broad Spectrum” protection with an appropriate SPF. Treat any cannabis-derived ingredient as a secondary benefit rather than the source of sun protection. It’s also wise to choose brands that provide certificates of analysis (COAs) verifying the purity and cannabinoid content of their products.
In short, a “marijuana-infused” sunscreen is an FDA-compliant sunscreen formula that includes cannabis-derived compounds as inactive, skin-conditioning ingredients. The UV protection still comes from approved mineral or chemical filters, while cannabinoids like CBD may offer added antioxidant and soothing benefits that support healthier skin in the sun.
