From creams to body oils to facial serums and more, there’s a good chance you can find a CBD-containing topical at a grocery store, pharmacy or specialty shop near you. Many of these products promise to clear, heal and otherwise soothe symptoms of eczema and other inflammatory skin conditions.

Cannabidiol, or CBD, is a cannabinoid, a chemically active molecule found in plants in the cannabis sativa family, which includes both marijuana and hemp. Unlike the best-known cannabinoid, THC (delta [9]-tetrahydrocannabinol), CBD isn’t “psychoactive.” In other words, it won’t get you high. Like THC, however, CBD has some potentially potent health effects.

“I think topical CBD is a very promising treatment for eczema; in theory, it could decrease itch, pain and inflammation. In the correct vehicle, it could also help heal the skin barrier,” said Peter Lio, MD, who is clinical assistant professor of dermatology and pediatrics at Northwestern University’s Feinberg School of Medicine and the founding director of the Chicago Integrative Eczema Center.

How can CBD help the skin?

Since the 1990s, scientists have known that humans (and many other animals) have a complex system of cannabinoid receptors running throughout the body, including in the skin. This endocannabinoid system helps regulate and normalize many physiological processes, including pain, mood, stress, sleep and immune system function.

The body makes its own cannabinoids that activate the system, and CBD and other plant-based cannabinoids also stimulate its healing effects. “Specifically, CBD has anti-inflammatory, anti-itch and anti-pain properties that make it extremely attractive as a medicinal compound, particularly in dermatology,” said Lio.

Is there any scientific evidence that CBD topicals improve eczema symptoms?

There are very few studies of topical CBD in people with eczema. A small study published in 2019 in Clinical Therapeutics that included a few people with atopic dermatitis found that a CBD ointment helped clear skin and reduced itch and the sleep loss it caused.

Research also suggests CBD is anti-microbial, with some data showing it works about as well as antibiotics to kill Staphylococcus aureus. Staph can infect the skin of people with atopic dermatitis, triggering flares and other complications.

“Evidence in humans is still pretty limited, which means it’s hard to know how well CBD works for eczema, or the key components necessary for success,” Lio said. Clearer answers about CBD and eczema may be available soon. The results from a trial of a CBD gel in about 200 people with moderate atopic dermatitis are due this year.

So, are CBD topicals safe—and worth a try—for people with eczema?

Research to date shows topical CBD is safe.

“I think that for adults who want to try a CBD topical, there’s little to lose,” said Lio, who noted he has many patients who said they benefit from the products. Like anything else applied to skin, CBD products can cause reactions, so test a small area over a few days before applying widely.

What else do I need to know before buying a CBD cream or oil?

Some CBD products are labeled “isolate,” which means CBD is the only cannabinoid they contain. Broad- and full-spectrum CBD products are made with multiple cannabinoids, sometimes including THC.

The U.S. Food & Drug Administration doesn’t verify how well specific CBD products work, whether they’re safe or if they contain the labeled compounds. Lio suggests asking your dermatologist to vet specific products.

Reputable manufacturers may also offer a certificate of analysis (COA). Often found on company websites, COAs are compiled by an independent, accredited laboratory and detail the quantities of a product’s various cannabinoids.

Are CBD products legal?

Usually, but state laws vary. CBD is legal on the federal level and in most states. THC is legal in some states but still illegal under federal law. Check the laws in the state you’re living or traveling in if you’re unsure.

Topicals made from this cannabis plant component are everywhere, promising better skin and more. While more research is needed, some experts think they’re worth a try for eczema.

Abstract

Objective: To investigate the therapeutic effect of CBD-ointment administered on severe skin chronic diseases and/or on their outcome scars.

Methods: A spontaneous, anecdotal, retrospective study of 20 patients with two most frequent skin disorders: psoriasis (n: 5 patients), atopic dermatitis (n: 5) and resulting outcome scars (n: 10). The subjects were instructed to administer topical CBD-enriched ointment to lesioned skin areas twice daily for three months treatment.

Results: Based on skin evaluations (hydration, TEWL, elasticity), clinical questionnaires (SCORAD, ADI, PASI), and supported by photographic data and investigators’ clinical assessment, the results showed that topical treatment with CBD-enriched ointment significantly improved the skin parameters, the symptoms and also the PASI index score. No irritant or allergic reactions were documented during the period treatment.

Conclusions: The topical administration of CBD ointment, without any THC, is a safe and effective non-invasive alternative for improve the quality of life in patients with some skin disorders, especially on inflammatory background.
