Key Takeaways
- CBD is a cannabinoid secreted by glands on the cannabis plant called trichomes, which protect the plant from weather and insects.
- CBD skin products are generally made from hemp, cannabis with low, non-intoxicating THC, so they will not get you high.
- CBD oil comes from hemp buds, leaves and stalks, while hemp seed oil comes from the seeds and contains no cannabinoids.
- Cutaneous ionotropic cannabinoid receptors affect pain and itch perception, epidermal balance, and the promotion and suppression of dermatitis.
- Topicals absorb into the skin rather than the bloodstream, usually working within minutes and lasting up to six hours, though physiology varies.
- Research on CBD in skin care is still early, and third-party lab reports show a product's purity and potency.
The Skinny on CBD (Cannabidiol)
CBD, or cannabidiol, is a chemical compound found in the cannabis plant. It’s one of a group of compounds called cannabinoids. Cannabinoids, like CBD, actually serve as skin care for the plant itself. There are glands on the surface of the plant, called trichomes, which secrete cannabinoids to protect the cannabis plant against the elements and insect predators, as well attract pollinators.While these plant-based cannabinoids, or phytocannabinoids, are great for the cannabis plant, they also have remarkable benefits for animals. All animals have an endocannabinoid system, which brings homeostasis, or balance, to many of the body’s other systems. The body produces its own cannabinoids, called endocannabinoids, which interact with receptors in the body’s other systems and, in doing so, help the body to regulate such functions as sleep, pain, inflammation, mood, memory, and much more.
Phytocannabinoids, such as CBD, act very much the same way. When consumed, the cannabinoids interact with these receptors, which then send messages to the body’s various systems to get working. Different cannabinoids have different specialties, in terms of their effects. CBN, for instance, is a cannabinoid that affects the nervous system in such a way that it relaxes the body for sleep. CBD has broader applications. It supports the body in a broad range of functions, making it sort of a Swiss Army knife as a wellness product.
CBD for Skin Care | Hemp vs. Marijuana
Since we’re throwing around the word “cannabis” here quite a bit, I just wanted to take a moment to differentiate the kind of plant we’re talking about when it comes to CBD skin products. Marijuana is the word we use to describe cannabis plants with large amounts of THC (the cannabinoid that people use to get high). CBD skin products, in general, are produced by the hemp plant, which is cannabis with low, non-intoxicating amounts of THC in it. So, in no way will the CBD skin-care products we are talking about get you high.CBD for Skin Care | Hemp Oil vs. Hemp Seed Oil
We should also make one more distinction. When we talk about CBD oil, we’re talking about oil derived from the buds, leaves and stalks of the hemp plant. Sometimes referred to as hemp oil, this is different from hemp seed oil, which is somewhat self-explanatory. It’s derived from the seeds of the hemp plant.One way to tell if you’re getting the right type of oil is to look for terms like full spectrum, broad spectrum and isolate. These refer to oils derived from the hemp plant’s buds, seeds and stems, but with different levels of filtering. If you see one of these terms in the ingredients, you should have legit CBD oil and not hemp seed oil.
None of this is to say that hemp seed oil doesn’t have its own benefits, as well. In fact, the oil derived from hemp seeds is rich in essential amino acids, such as omega-3 and omega-6 fatty acids, plus wellness-boosting vitamin E. It does not contain any cannabinoids, though. Still, hemp seed oil has been found to have beneficial effects on skin conditions and anti-aging.
But let’s get back to CBD, skin care and the endocannabinoid system.
Does the Endocannabinoid System Affect Your Skin?
We mentioned the receptors that endocannabinoids trigger in various systems of the body. One group of such receptors are called cutaneous ionotropic cannabinoid receptors. These receptors affect such functions as pain and itch perception, epidermal homeostasis (that is, balance), and the promotion and suppression of dermatitis, which is the inflammation of the skin.You’re probably starting to connect the dots, right? If the endocannabinoid system helps to regulate various functions of the skin, and cannabinoids (most notably, CBD) stimulate the endocannabinoid system, then it’s easy to deduce that CBD has the potential to be a valuable tool for skin care.
