What Is CBD Oil?
CBD (also known as cannabidiol) is the non-intoxicating component of marijuana or hemp plants. CBD is extracted as a powder, and is typically mixed with an oil like olive, hemp, or coconut, all of which enhance application and effectiveness, hence the name “CBD oil”.
CBD oil in skin care won’t get you high because it doesn’t have the mind-altering properties of marijuana’s tetrahydrocannabinol (THC) content. It’s extracted from the flowers, leaves, stalks or stems of the hemp plant, whose THC content is exceptionally low (often so low it cannot be detected by testing equipment).
It is also important to know that CBD oil is not the same thing as hemp seed oil, which is another great ingredient for skin. The two are often marketed interchangeably, but CBD oil is richly concentrated in cannabidiol, whereas hemp seed oil only contains trace amounts of cannabidiol, if any.
For products claiming to contain CBD, the regulated name that should be on the ingredient label is cannabidiol (this regulated labelling is called the International Nomenclature of Cosmetic Ingredients—INCI). All other alternative names on ingredient labels, such as CBD-enriched hemp seed oil, may or may not mean the product actually contains cannabidiol. Regardless, to be 100% certain, you can always ask the company for their product’s specification, which is called an assay.
CBD for Acne-Prone Skin
Research has firmly established that acne is an inflammatory condition. Although multiple factors trigger acne, we know that anything you apply to skin that can reduce inflammation and help soothe skin (that's where CBD comes in) is likely to visibly reduce breakouts, especially acne-related redness.
Numerous studies have shown that CBD oil has anti-inflammatory benefits when applied to skin. This makes CBD a suitable ingredient for acne-prone skin, while its calming benefits help reactive skin look and feel better.
Research also shows that CBD has the potential to decrease excess sebum (oil) production, possibly due to its balancing effect on the flow of the skin’s oil.
Despite such encouraging news, most scientists studying CBD agree that more conclusive, scientific studies are needed to confirm these initial results.
CBD Oil for Wrinkles and Anti-Ageing
Because it comes from a plant, it’s not surprising that CBD oil also has antioxidant properties. The antioxidants in CBD are one-way topical use helps lessen the visible signs of ageing. By counteracting free-radical damage and reducing the look of inflammation, CBD anti-ageing creams visibly diminish issues like wrinkles, skin dullness, and ruddy skin tone.
Of course, there are plenty of other antioxidants out there that can make the same claims, so CBD isn’t the only or “best” antioxidant to seek out; rather, it’s just one of many to consider, and the more of these ingredients you give to your skin, the better.
CBD Oil for Sensitive Skin
Another benefit of CBD oil is that it has been found to have significant soothing properties. Its substantial skin-calming and skin-normalising effects can help minimise issues related to skin sensitivity, including redness and reactivity. Since all skin types are affected daily by environmental stressors, CBD’s soothing mechanism can help keep everyone’s skin in check.
How to Find the Best CBD Skin Care
With so many CBD skin care products* available, you need to know what to look for so you can be sure you’re finding the best CBD oil (or other types of CBD skincare). Here are some CBD shopping tips:
- Make sure the ingredient list states “cannabidiol”. As mentioned above, other terms aren’t INCI-compliant, nor is hemp seed oil or extract the same as CBD oil.
- Many brands selling CBD skin products list the total cannabidiol content in milligrammes, sometimes further broken down per use. This is a good indicator that the CBD product is legitimate, although there’s currently no consensus on how much CBD skin needs per application; we just know skin has receptor sites for this ingredient that when connected, can interrupt signals that cause the skin to act up.
- Ask the brand or check to see if they provide evidence of third-party certification on the purity and stated amount of the CBD to be sure you’re getting what the label claims.
- Look for CBD skin care in stable packaging - no jars, clear bottles or any component that exposes this delicate plant ingredient to a lot of light or air, which causes it to become less effective.
- Some brands advertise their CBD as being “isolate”, “full spectrum”, or “broad spectrum”. None of these terms are regulated, but they can be helpful differentiators:
- CBD isolate means pure CBD, no other cannabinoids or other naturally occurring substances like flavonoids or terpenes.
- Full spectrum CBD means everything that occurs in the hemp plant alongside the CBD, including trace amounts of THC and other cannabinoids such as CBG (cannabigerol) and antioxidant compounds.
- Broad spectrum CBD means no THC is detectable. Trace amounts of THC can be detected in full spectrum CBD, but must fall below 0.3% in order to not be considered active.
The bottom line: As long as it’s extracted within the proper parameters, CBD oil does have benefits for skin. We’re excited to see how the research behind CBD oil’s topical benefits continues to grow, and anticipate it becoming a mainstay of many people’s skincare routines.
*Disclaimer: According to the Central Narcotics Bureau in Singapore, it is against the law to supply or import products with hemp derivatives as an ingredient, such as CNB oil. Cannabis and its derivatives are classified as Class ‘A’ controlled drugs in the First Schedule of the Misuse of Drugs Act. In Singapore, there is a strict policy of zero tolerance towards controlled drugs. The importation/exportation, possession, sale and consumption of controlled drugs or products containing controlled drugs, even in trace amounts, is an offence. Importers and retailers found to be dealing with controlled drugs or products containing them will be subject to an investigation where legal action can be taken against these offenders.
