Most regular chapsticks rely on proven occlusives such as petrolatum and mineral oil, often paired with humectants like glycerin and waxes to trap water and smooth rough texture. Petrolatum in particular has strong clinical support for reducing transepidermal water loss (TEWL)—the main cause of chapping—and for helping restore barrier function. Dermatological studies show that petrolatum-based formulas significantly improve barrier integrity and hydration, which directly benefits the delicate, moisture-prone skin of the lips.
Cannabis chapstick can refer to two main formulations. Many use hemp seed oil, which contains no cannabinoids but is valued for its fatty-acid profile—especially linoleic and alpha-linolenic acids—that support softness and barrier lipid health over time. Others include cannabidiol (CBD) as an active ingredient. Hemp seed oil’s composition is well-suited for emollience; however, like most plant oils, it primarily serves as a softener rather than a heavy-duty occlusive on its own.
The presence of CBD in a lip balm adds another dimension. Early dermatology reviews suggest that topical cannabinoids may have potential in addressing itching and inflammation, but current evidence remains limited, with small studies and few direct comparisons to standard lip-care ingredients. As of now, there is no solid clinical data showing that CBD-infused lip balms outperform traditional occlusive-based chapsticks for common chapped lips. The research remains promising but inconclusive for general lip hydration.
Regulation and labeling are also important considerations. In the United States, the FDA continues to monitor CBD in consumer products and has issued warnings for unsupported claims or inaccurate labeling. While this doesn’t imply that CBD balms are unsafe, consumers should prioritize brands that provide clear cannabinoid content, third-party batch testing, and responsible marketing. If a cannabis lip balm contains only hemp seed oil and no CBD, it functions as an emollient rather than an active cannabinoid product.
When comparing effectiveness, regular chapsticks containing petrolatum (and/or waxes) combined with humectants have the most direct evidence for reducing water loss and quickly restoring moisture. Many modern lip balms—those blending petrolatum, waxes, and glycerin—perform consistently well in both laboratory and user evaluations. Cannabis-branded balms can also be effective, particularly if they combine hemp seed oil with petrolatum, waxes, or SPF protection. However, formulations relying solely on plant oils may not seal in moisture as effectively.
For practical use, individuals with cracked or sore lips should start with a simple, fragrance-free, petrolatum-based balm applied frequently throughout the day and before bed. Cannabis-infused options may be ideal for those seeking a richer texture, plant-derived ingredients, or added antioxidants. The most effective formulas—cannabis-based or not—combine an occlusive to lock in moisture, a humectant to attract hydration, gentle emollients for comfort, and minimal fragrances to reduce irritation.
