Is CBD Good For Your Skin?
9.20.22

Is CBD good for your skin and should it be incorporated into your skin care routine? CBD claims are everywhere and can be down right outlandish. Let's take a look at fact vs fiction when it comes down to what cbd can really do for your skin. We'll examine these cbd skin care facts based on science and debunk any myths you might have heard about this promising new ingredient.

"Though a body of preclinical evidence suggests topical application of CBD may be efficacious for some skin disorders, such as eczema, psoriasis, pruritis, and inflammatory conditions, confirmed clinical efficacy and elucidation of underlying molecular mechanisms have yet to be fully identified."

Does CBD treat skin conditions?

Let's be clear, there has been no peer reviewed studies that show any conclusive evidence that CBD treats any skin disorders/conditions. However, there have been a handful of studies conducted on mice and rats and a few "anecdotal" studies. Let's take a look...

"In one study, patients with mild to moderate scalp psoriasis or seborrheic dermatitis were given a shampoo containing cannabidiol. After 14 days of use, the level of itching and redness had decreased in the patients.

In a second very small study of 16 patients, they were asked to evaluate the effect of a topical cannabidiol lotion on their eczema. After 2 weeks of use, the patients “self-reported” an modest improvement in the severity of their eczema.

In a third small study, patients treated topically with 8% CBD reported having less nerve pain.

NOTE: in addition to the above studies, a non-clinical study with only  3 individuals suffering from a rare skin blistering disease, epidermolysis bullosa, applied a topical CBD oil to their skin and all 3 reported less blistering."

CBD and Inflammation?

At this time there is no scientifically published human data on any anti-inflammatory effect of CBD topically applied (are you sensing a theme here?). However, a few studies conducted under a microscope have shown that CBD may "lower the level of the inflammatory mediator, TNF-alpha, in leukocytes, block IL-6 and IL-8 production in human monocytes and macrophages, lower COX-2 (PGE-2) expression in macrophages, and block inflammatory cytokines in keratinocytes (Pellati, F; et al; (2018) Biomed Res. Intl. ID. 1691428)." What does that mean? It means that initial research on human cells grown in culture suggests that CBD may have some anti-inflammatory effects.

CBD and Pain?

One recent study (Xu, DH. et al. 2019, Curr.Pharm.Biotechnol.) conducted with a small group of patients (29) showed that an 8% topical solution of CBD could possibly reduce pain caused by neuropathy.

CBD and Cancer Cells?

Here's where it gets interesting. CBD likely effects one or both of the endocannabinoid receptors, CB1 and CB2. Both of these receptors have a role in tumor progression, with CB2 being a key factor in stimulating breast cancer growth and tumor aggressiveness. By blocking the activity of these receptors, CBD may lower cancer cell growth and play a role in the death of the cancer cell. This study is in interesting read on CBD and breast cancer, see Kiskova, T. et al. (2019) Intl. J. Molec.Sci. 20: 1673-1694.

There is currently no published data that topical CBD provides any benefits for normal skin, and no data showing any anti-aging benefits. However, the enthusiasm for incorporating CBD as an ingredient in your skin care routine seems warranted, but make no mistake, there is no PROVEN data for these claims so beware of any claims. Do your own research and make a conclusion on whether it is worth trying skincare products containing CBD.
