You can find different types of CBD products in the market like CBD oils, e-liquids, edibles, and topicals. CBD topicals are one of the most innovative ways to use CBD and it involves rubbing the product on the affected area. While using topical CBD products like CBD salves, creams, lotions, and creams, the CBD in the product will not reach the bloodstream. However, the case with a transdermal CBD patch is different.
Transdermal CBD patches are applied to the skin and it releases the cannabinoids to the body of the user and the cannabinoids ultimately reach the bloodstream. You can find CBD transdermal patches in the market whose effects last for up to 96 hours. Here, we discuss CBD transdermal patches in detail. Read ahead to know.
Transdermal CBD Patches
Transdermal CBD patches are comparatively new and resemble a sticking plaster. These are infused with a measured amount of CBD that is combined with permeation enhancers. These patches work by making use of a drug concentration gradient. They contain large quantities of CBD that will spread to areas with low CBD concentration. Our skin has a low concentration of CBD and this difference pulls the CBD in the transdermal patch to the skin.
The CBD patch should be placed on a clean area of the body that has a high concentration of veins. This will allow for an improved rate of CBD absorption into the bloodstream. The advantage of using CBD patches is that the CBD will be passed straight to the cells of the skin. As cannabinoids like CBD are lipids, they can easily diffuse through the skin and reach the blood vessels.
As per the experts, transdermal delivery of CBD is relatively slow and inefficient. This is because our skin is adept at keeping out external compounds, contaminants, and toxins. This is why some of the CBD transdermal manufacturers add permeation enhancers to the patches to help the CBD to bypass the protective layers of the skin. Also, the essential oils and terpenes that are found in the hemp plant can act as permeation enhancers.
Transdermal CBD Patches Ensure Higher Bioavailability
The bioavailability of CBD relates to its absorption rate. The bioavailability of orally consumed CBD is between 4 and 20%. However, the bioavailability of transdermal and topical CBD products is high. The bioavailability rate of these delivery methods is around 45%. The reason for the higher bioavailability is because the CBD present in these patches bypasses the digestive system and the liver.
