The absorption of CBD when used for the skin can be via oral or topical route. You can choose either of the two but it’s best to consider the bioavailability of the product.
Bioavailability refers to your body’s absorption of CBD from the area of administration to the bloodstream. Generally, topical products don’t have high bioavailability, however, they allow direct absorption on the applied area. Unfortunately, there are only a few studies that explain how CBD topicals work. Only anecdotal evidence and a handful of preclinical studies have proved its benefits when used topically.
Furthermore, CBD-infused topicals are commonly used on external problems like acne, itching, local inflammation. Such products are formulated with transdermal properties to penetrate the epidermis and produce its local, non-systemic effects. So if you have mild, local external conditions, it’s best to use topical products such as salves, lotions, creams and moisturizers.
There is a plethora of skin products infused with CBD in the market — including serums, sprays, soaps, lotions, cleansers and more. To use them, simply follow according to the directions on the label.
However, for systemic or severe conditions, it’s best to consult your doctor first and get proper medication before using CBD orally as supplement for your skin.
