Dermatologists are intrigued—but cautious—about sun products that incorporate cannabis-derived ingredients like CBD alongside traditional SPF filters. Their consensus is clear: true UV protection must come from FDA-recognized active ingredients such as zinc oxide, titanium dioxide, or avobenzone. While cannabinoids show promise as antioxidants, they are not approved sunscreen actives and should never replace a broad-spectrum SPF 30 or higher applied properly and consistently.

In the United States, sunscreens are regulated as over-the-counter (OTC) drugs. This means the FDA establishes which active ingredients, labeling, and testing standards define a safe and effective sunscreen. Because cannabinoids like CBD or THC are not listed as approved UV filters, any marijuana-infused sunscreen still depends on conventional UV-blocking ingredients to earn its SPF rating. For this reason, dermatologists evaluate these formulas in the same way as any other sunscreen—checking for broad-spectrum coverage, water resistance, and verified testing.

So where does CBD fit in? Early studies suggest that CBD could support photoprotection when used in combination with sunscreen. Research points to its anti-inflammatory and antioxidant properties, which may help reduce redness, calm skin, and promote recovery from UV-induced damage. Some lab-based and small human studies have shown that CBD-infused creams can minimize oxidative stress and inflammation in sun-exposed skin, potentially aiding post-sun repair. Still, dermatologists emphasize that this is emerging science and not yet definitive.

Most experts agree that CBD can be a beneficial skincare ingredient—particularly for soothing irritated or sensitive skin—but it should complement, not replace, traditional sun protection methods. Dermatologists remain cautious about overstated claims, stressing that SPF ratings are earned through strict testing based on recognized actives, not from the addition of cannabinoids. Until larger and more conclusive clinical trials are completed, CBD’s benefits in sun care should be viewed as supportive rather than primary.

For consumers, the guidance remains simple: choose sunscreen based on SPF strength, broad-spectrum protection, and proven UV filters. Look for SPF 30 or higher, apply generously, and reapply every two hours when outdoors. If a product includes CBD or hemp oil, consider it a possible “bonus” for added hydration or antioxidant support. Those with sensitive or acne-prone skin may find mineral-based sunscreens (with zinc or titanium dioxide) still offer the best protection with fewer irritants.

Lastly, buyers should be mindful of the legal and regulatory differences between CBD and THC topicals. While CBD derived from hemp is legal at the federal level, marijuana-derived ingredients may face state-by-state restrictions. Consulting with a dermatologist can help consumers choose products that meet both their skin needs and local regulations.
