Already used to treat nausea, pain, and inflammation, CBD and THC, compounds found in cannabis, are also being used as medications for skin conditions like psoriasis and dermatitis.
Their effectiveness has been confirmed by a study published in the Journal of the American Academy of Dermatology.
What is Psoriasis?
Psoriasis is an autoimmune and genetic condition. The endocannabinoid system plays a role in regulating the life cycle of skin cells. In recent years, research and anecdotal evidence from people have shown that CBD and THC oils and balms can reduce inflammation and slow down the growth of skin cells.
When psoriasis occurs, skin cells tend to replace themselves more frequently—every 3-5 days instead of every 30 days, as is normal.
This rapid and excessive growth of the epidermal layer causes red patches accompanied by itching, which in the worst cases can lead to skin flaking. These symptoms can be localized in a specific area of the skin or spread across the body.
The Role of the Endocannabinoid System in Skin Health
The endocannabinoid system, present throughout the body, including in the skin, plays a fundamental role in regulating cellular functions. CB1 and CB2 receptors, activated by cannabinoids such as CBD and THC, can modulate the inflammatory response and reduce cellular proliferation—both important factors in treating psoriasis and dermatitis.
CBD in Managing Psoriasis and Dermatitis
CBD, known for its anti-inflammatory and antioxidant properties, is particularly useful in reducing the symptoms of psoriasis and dermatitis. CBD works by reducing the production of cytokines, proteins responsible for inflammation, and slowing the growth of skin cells, which can alleviate the formation of red and scaly patches.
In addition to reducing inflammation, CBD is effective in relieving itching and improving the appearance of psoriasis-affected skin.
THC and Skin Health
THC is primarily known for its psychoactive effects, but it also has a positive impact on skin health. Recent studies have shown that THC can reduce inflammation and slow cellular proliferation, making it useful in treating skin conditions such as psoriasis and dermatitis.
A team of researchers from the University of Colorado School of Medicine observed a link between the injection of tetrahydrocannabinol (THC) and a reduction in skin diseases, including psoriasis, itching, and both atopic and contact dermatitis.
Additionally, THC has shown potential in reducing tumor growth in melanoma-afflicted mice, one of the most lethal forms of skin cancer.
Scientific Studies and Clinical Evidence
The Journal of the American Academy of Dermatology has published numerous studies showing that cannabinoids, particularly CBD and THC, are effective in treating inflammatory skin conditions. These studies demonstrate that cannabinoids not only reduce inflammation but can also inhibit the accelerated cell growth typical of psoriasis.
Other studies indicate that THC has beneficial effects on melanoma, one of the most dangerous skin cancers. The findings suggest that THC could inhibit the proliferation of cancer cells.
Topical CBD and THC Products
Today, many topical products containing CBD and THC are available on the market for treating skin conditions. These products include oils, creams, balms, and lotions. Applying CBD or THC directly to affected areas can alleviate symptoms of psoriasis and dermatitis, reducing inflammation, itching, and flaking.
How to Use CBD and THC Products
- Skin cleansing: Ensure the affected area is clean and dry before application.
- Application: Apply the cream or oil in adequate amounts and gently massage until fully absorbed.
- Frequency: Follow the instructions on the packaging, typically suggesting 2-3 applications per day.
- Monitoring: Observe changes in the skin and consult a doctor if necessary.
Future Outlook and Regulation
While CBD is widely accepted and available in many countries, THC remains subject to legal restrictions in several regions. However, with increasing research confirming the medical benefits of cannabinoids for skin health, it is likely that we will see greater acceptance and availability of cannabis-based treatments for dermatological conditions.
