Eczema (dermatitis) is a skin condition that causes patches of irritated, itchy, dry, inflamed skin. There are many types of eczema. While the exact cause is unknown, genetics, environmental factors, and the immune system are believed to be potential causes and triggers.
Hemp Seed Oil vs. CBD
To do a patch test, apply CBD oil to a small area and watch for 24 hours to check for any side effects (e.g., itching, redness, swelling).
A Word From Verywell
In your search for plant-based remedies for treating eczema, you may have come across different options that derive from cannabis and hemp plants, including hemp seed oil, hemp oil, and CBD oil.
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.
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.
Is there any scientific evidence that CBD topicals improve eczema symptoms?
“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.
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.
How can CBD help the skin?
“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.
