The subject of topical vs transdermal CBD products and how they differ has become pretty popular with the introduction of some new products into the CBD world. One of the most heavily debated topics currently is that of transdermal CBD products and what sets them apart from topicals.
Understandably, there is some confusion out there about the following question – “What is the difference between topical and transdermal CBD products?”
Topical CBD Products
CBD lotions, salves and balms are available from many CBD companies. These topicals make up most of the market today. Topicals are applied to the skin but they only work ON the skin. They generally work on the top 3 layers of the skin, it’s surrounding area, and that’s it. Topical CBD products do not penetrate THROUGH the skin, nor does any of the CBD get into the bloodstream.
If you take your sublingual CBD oil and apply it to your skin, that is topical not transdermal. This is largely why you can apply THC topically as well and not experience any psychoactive effects. Likewise, it will be unlikely to trigger a positive drug test.
Transdermal CBD Products
Transdermal CBD products are different. These are products also applied to the skin. But they actually absorb into and penetrate through the skin. Some of the CBD will enter your bloodstream and the CBD is delivered deeper into muscle tissues.
This means it can not only work as a localized effect, but also throughout your whole body. It takes special emulsifiers and chemical compounds to make a CBD product transdermal which is also why they tend to be more expensive.
A More In-Depth Look
You’re probably thinking, “How do topicals work if they don’t absorb through the skin?” The short answer is that your skin has CB1 and CB2 receptors that the cannabinoids interact with when they are applied.
Again, it’s important to note that the receptors in the general area are what will be activated when CBD is used topically. One should not expect CBD applied topically to their wrist to have any impact on, say, a migraine. This is a limitation of topical products.
So what if you do want the CBD or other cannabinoids applied on your skin to have a whole-body effect rather than local? That’s where transdermal CBD products come in. Transdermal CBD products take superiority over topical products.
Why are Transdermal CBD Products Superior?
Transdermal not only works locally on those receptors. It also gets into the bloodstream and is able to reach other parts of the body. It’s not uncommon to apply some transdermal CBD products to the back of the neck, for example, to get some relief for a migraine.
You should still ideally apply the transdermal product directly where the pain is for some boosted targeted relief. But it’s not 100% essential like it is with topicals.
In some cases, the transdermal CBD products being used are not creams or lotions that can be applied directly over the area that hurts. Instead, they’re in the form of CBD patches.
These patches are applied to a veinous area such as the inner wrist and worn for around 8 hours. An example of the aforementioned transdermal creams or lotions is Myaderm, a transdermal cream produced with CBD isolate derived from hemp.
Higher Bioavailability of Transdermal CBD Products
It’s also important to note that transdermal CBD products tend to be touted as extremely high in bioavailability. We’re on the hunt for a study to get exact numbers, but our discussions with the pharmacists at these companies producing the transdermal products claim it is in the 70% range.
If accurate, this puts transdermal CBD products well above sublingual or even vaping as far as bioavailability is concerned.
Which Should I Try? Which is Best?
Understandably, transdermal CBD products tend to be on the more expensive side. They require special emulsifiers and permeability enhancers to get the cannabinoids at a point where you can absorb them through the skin.
This costs much more than what it costs to make traditional topicals. An average consumer could easily make a DIY topical in their home with some crystalline isolate and coconut oil. The same cannot be said for transdermal CBD products, at least not safely.
Furthermore, you also need to take drug testing into account when deciding which products to try. Since transdermal products do get the cannabinoids into your bloodstream, any potential THC in the products has the possibility to trigger a positive drug test result. Topicals, provided they are kept away from cuts and mucous membranes, pose no such risk.
How Do I Know if a Product is Transdermal or Topical?
As previously stated, the majority of the products out there currently are topicals. If it does not explicitly state on the labeling that the product is transdermal, chances are it is topical. Transdermal is technology that companies understandably want to advertise and likely would have labeled the product as such.
However, if you are unsure, contact the company and ask directly. Take a look at the ingredients on the label and see if it lists any permeability enhancers or emulsifiers. Do the instructions require you to apply the product near a veinous area, or clean the area with an alcohol wipe? Another indication may be the price, since transdermal CBD products are generally more expensive products.
