With marijuana-based skincare continuing to grow, products like cannabis-infused sunscreens, lotions, and after-sun balms have entered the mainstream beauty and wellness market. While many consumers report positive experiences — from improved hydration to reduced inflammation — some individuals may experience unwanted side effects depending on their skin type, ingredient sensitivities, or the quality of the formulation.
Understanding the Ingredients
Marijuana sun protection products typically contain cannabidiol (CBD), hemp seed oil, or, in some cases, low levels of tetrahydrocannabinol (THC). These compounds are blended with traditional SPF ingredients like zinc oxide, titanium dioxide, or chemical UV filters. The cannabis-derived components themselves are generally considered safe and non-psychoactive when used topically, according to reports from the World Health Organization and dermatology research published in the Journal of Clinical and Aesthetic Dermatology.
However, the overall safety of a marijuana sun product depends on the full ingredient list — including preservatives, fragrances, or essential oils — which can sometimes trigger irritation or allergic reactions in sensitive individuals.
Common Skin Reactions
Like any topical product, marijuana SPF lotions and sprays may cause redness, dryness, or itching, particularly in those with eczema, psoriasis, or very sensitive skin. Some users have reported mild irritation from terpenes or botanical additives found in full-spectrum cannabis extracts. Additionally, formulations using synthetic fragrance oils or alcohol-based carriers can increase the risk of photosensitivity — a condition where the skin becomes more sensitive to sunlight.
To minimize risks, dermatologists often recommend performing a patch test before applying a marijuana SPF product over large areas of the body. Testing the product on a small area (such as the inner arm) for 24 hours can help determine if any reaction occurs.
Quality and Label Accuracy
Another potential concern involves mislabeling or lack of regulation. Studies from the Journal of the American Medical Association found that many CBD-infused products are inaccurately labeled, with some containing less or more CBD than advertised. In some cases, traces of THC or contaminants such as heavy metals, pesticides, or residual solvents have been detected in untested formulations.
Consumers should look for third-party lab certifications or Certificates of Analysis (COAs) to confirm product purity and cannabinoid content. Brands that openly share their testing data and adhere to FDA cosmetic manufacturing standards offer greater assurance of safety.
When to Consult a Professional
While adverse side effects are relatively rare, anyone experiencing persistent irritation, rashes, or acne breakouts after using a marijuana SPF should discontinue use and consult a dermatologist. Pregnant or breastfeeding individuals, or those with autoimmune or chronic skin conditions, should also discuss cannabis skincare products with their healthcare provider before use.
The Bottom Line
Marijuana sun protection products can provide benefits like anti-inflammatory relief and antioxidant support, but quality, formulation, and personal skin sensitivity matter greatly. Choosing dermatologist-tested, lab-verified, fragrance-free options helps ensure safe sun care while enjoying the wellness benefits of cannabis-infused ingredients.
