CBD shows promise, and may offer skin benefits, but scientific evidence is needed.

This is part 2 in a 2-part series.

Part 1: A Closer Look at CBD

Before the legalization of cannabis in most of the United States, studies researching related skin benefits were almost nonexistent.

Now, its newfound mainstream popularity boasts anti-inflammatory and analgesic properties. In addition, scientists are finding more evidence for its use in treating dry skin, psoriasis, eczema, and acne.5

In a recent 2019 study, “A therapeutic effect of cbd-enriched ointment in inflammatory skin diseases and cutaneous scars,” researchers examined 20 patients suffering from psoriasis (n=5), atopic dermatitis (n=5), and resulting outcome scars (n=10) to whom they administered topical CBD-enriched ointment to lesioned skin twice daily for three months.5

After three months, researchers saw improved skin and inflammatory symptoms in study participants.

“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,” according to the study. “No irritant or allergic reactions were documented during the period treatment.”

A 2014 study in the Journal of Drugs in Dermatology also found that CBD could help to suppress acne breakouts by regulating oil production of the sebaceous glands.6

Still, while Dr. Zirwas says CBD shows promise, nothing has been scientifically proven. CBD products may very well work, he says, but he emphasizes that there is no evidence that they do.

Even so, not all CBD is considered equal.

When discussing CBD with patients, Dr. Zirwas explains that while there is no scientific evidence that CBD works, topical CBD is unlikely to cause problems. Furthermore, it’s hard to know which products have quality CBD.

He suggests referencing ConsumerLab.com for insightful reviews of CBD supplements.

As for the need for concrete evidence in this area, Dr. Zirwas says, “A small, double-blinded study would be needed at minimum to establish the credibility of CBD products. Nothing anecdotal, no case report, no case series, nor any open label study could make it credible.”
