Learn about CBD’s anti-inflammatory, antipruritic, anti-aging and antioxidant properties as an alternative to traditional treatments for skin afflictions.
Cannabinoids have demonstrated their anti-inflammatory, antipruritic, anti-aging and anti-tumor properties through various mechanisms, including the Endocannabinoid System. This discovery may be an alternative to traditional treatments for skin afflictions. In this article we focus on the therapeutic properties, for our skin, of one of the most studied phytocannabinoids, Cannabidiol.
Cannabidiol, known by its initials, CBD, is a substance present in the Cannabis Sativa L plant. The WHO recognizes its medicinal and therapeutic potential due to its multitude of anti-inflammatory, antioxidant, analgesic, antibacterial and anxiolytic properties.
We will start by defining what our skin is. Our skin is the largest organ of our body, it accounts for 1/7 of our weight and is made up of a complex multilayered barrier, whose function is to protect us from external factors. Our skin consists of 3 layers: the epidermis, the dermis and the hypodermis.
The skin has a multitude of functions and its relationship with other parts of our body is important. It is part of our neuro-immuno-endocrine network which we can regulate through our Endocannabinoid System.(2)
Our Endocannabinoid System, also known by its acronym in English, ECS, is a system discovered just 30 years ago. The ECS is known for its regulatory function of almost all the physiological functions you could imagine. We’re talking about a complex intercellular communication system in charge of regulating different processes in our body, one of the organs where it is present is our skin. In recent years, the important role of ECS in regulating the processes of our skin has been discovered. This is due to the discovery of cannabinoid receptors in our skin.(2) In a 2019 study “Cannabinoid Signaling in the Skin: Therapeutic Potential of the Endocannabinoid System”, the intrinsic role of the ECS in the regulation and balance of our skin is gathered, noting that a variety of afflictions such as; Atopic dermatitis, psoriasis, acne, depigmentation, itching, and some tumors can originate from ECS imbalances. The ECS regulates such important functions of our skin as:
CBD offers a multitude of benefits without any known serious side effects. It should be noted for its regulatory and but not overly inhibitory action. Many of the substances that are used to treat diseases and topical problems include potent, and sometimes harmful, chemicals, steroids, corticosteroids or other ingredients that are responsible for strong inhibition of beneficial natural processes that create uncomfortable symptoms, but they do not get to the root of the problem. Inhibiting natural processes makes it harder for our body to reach homeostasis, this includes our skin.(6) CBD interacts with our skin by activating the Endocannabinoid System to help regulate its processes, offering its anti-inflammatory, antioxidant, analgesic properties. It is one of the most studied cannabinoids with promising results for the treatment of topical afflictions such as atopic dermatitis, acne, pruritus and psoriasis.(5)(6)(7)
Now that we have a better understanding of how our skin, the Endocannabinoid System and CBD work, let’s distinguish how CBD can help different types of skin.
CBD’s anti-inflammatory and analgesic properties can help calm and reduce itchiness in people with atopic dermatitis. Cannabidiol has been studied for a variety of topical afflictions including atopic dermatitis (eczema), psoriasis, and pruritus (chronic itching). These topical afflictions are autoimmune diseases, that is, the immune system itself is unbalanced and damages healthy tissues and / or organs. One of the substances that is most used to treat these afflictions are corticosteroids. Corticosteroids are immunosuppressive substances whose job is to shut down inflammatory immune processes, processes that are beneficial and necessary for fighting infections so long as they are not attacking our own system. That is why corticosteroid treatments can make people more susceptible to infection and are suitable only for certain cases. On the other hand, Cannabidiol offers us a natural option that helps regulate but does not appear to inhibit our immune system, enabling our body to reach a balance so that our immune system won’t attack our healthy tissues, but is still able to respond to infections.(9) Numerous studies show the capacity of CBD to activate anandamide, this endocannabinoid has a series of antipruritic and analgesic properties that inhibit TRPV1 activity on pain-sensing neurons and itch-sensing neurons, called nociceptors. Overactive or hypersensitive TRPV1 activity can lead to excess transmission of pain and the sensation of itching, which is why reducing TPRV1 activity may offer a promising treatment for people with atopic dermatitis or pruritus.
Acne is one of the most common skin afflictions and affects 80% of people at some point in their life. Treatments focus on reducing the amount of oil, bacteria, and skin inflammation. Before we talked about the functions of the Endocannabinoid System in our skin, one of the functions is sebum production (our natural oils) regulation. Appropriate levels of sebum production is protective, aiding in our skin’s elasticity, barrier function, and much more; however, people with oily or acne-prone skin over-produce these natural oils which can clog pores and allow bacteria to grow. CBD regulates the production of lipids (such as sebum) in addition to containing antibacterial properties, making it a perfect substance to help balance our skin’s oil production and prevent the appearance of infections and blackheads (1). Its anti-inflammatory effects also help lower the redness, swelling, and pain associated with acne breakouts to ease uncomfortable and painful symptoms. In preclinical studies, CBD is shown as a potential cannabinoid for the treatment of acne vulgaris. CBD suppressed sebocyte proliferation by activating the TRPV4 receptor, influencing the regulation of glucose and lipid metabolism.
CBD can be a great ally for people with sensitive skin. It regulates the production of sebum, reduces redness, calms, hydrates and provides a natural glow to the skin. Its great potential to regulate skin processes offer a natural remedy to soothe and calm the dermis. Its anti-inflammatory properties help reduce redness of skin prone to irritation and itch.
CBD not only contains high levels of antioxidants, but may also tell our skin to engage its natural antioxidant pathways. These antioxidants and antioxidant pathways work together to prevent damage, slow down the skin’s ageing process, and smooth wrinkles by fighting free radicals and contamination. The endocannabinoid system has an important role in regulating the regeneration of the skin cells, also known as cell turnover. If we enhance our endocannabinoid system with CBD, we can ensure quality cell turnover, replacing dead skin cells with news one and preventing excessive accumulation that can make our skin look dull, helping our skin regain its natural glow.
Right now most of the cannabinoid studies focus on CBD and THC due to their increased presence in the Cannabis Sativa L plant. However there are more than 113 cannabinoids with different promising effects. More research is needed but every day we get closer to knowing more about this plant and its beneficial uses for our skin. Here are some of the next cannabinoids to enter the market.
Conclusion Most studies on the dermatological treatment of CBD are preclinical with a few exceptions of clinical evidence. However, research within the scientific community is continually identifying properties of Cannabidiol and other cannabinoids that suggest it can nourish our skin and may help treat certain topical afflictions such as atopic dermatitis, psoriasis, premature ageing, itching, acne and redness. Doing so with fewer harmful results than traditional treatments. Sources:
