CBD & Skincare

The Endocannabinoid System & Your Skin Cannabidiol (CBD) is a non-psychoactive compound extracted from the cannabis plant that can be applied on the skin to interact with our ECS for beneficial effects on the skin’s microbiome such as water retention, anti-inflammatory and anti-oxidant.1,2

The Endocannabinoid System & Your Skin

What is the Endocannabinoid System?

CBD and other cannabinoids interact with the skin’s ECS. The ECS plays an important role in regulating and balancing the normal function of the skin.1 The ECS includes cannabinoid receptors and endocannabinoids, which are located in various compartments of the skin layers including the epidermis, hair follicles and sebaceous (oil) glands.1-3 The maintenance of a healthy skin barrier and its functioning is achieved through the interactions of these communication pathways. These endocannabinoids are released on demand, which means that it depends on the needs of the skin in order to know when and how to balance its physiological functioning.

How CBD Works on Your Skin

CBD binds to receptors in the skin that are critical to maintaining a healthy skin barrier and a balanced skin homeostasis1,2. Some of these receptors are known as endocannabinoid receptors, CB1 and CB2, that are critical to maintaining a fine-tuned barrier by regulating skin growth, immune responses, pain and touch sensation. 22 CBD binds to receptors in the skin that are critical to maintaining a healthy skin barrier and a balanced skin homeostasis1,2. CBD has also been shown to bind to other receptors present on immune or nerve fibers, providing a wide range of benefits in healthy and damaged skin cells2

CBD has been shown to:

• Interaction with key receptors responsible for retaining water in skin layers1,2.
• Demonstrate anti-inflammatory effects to decrease inflammation throughout skin layers that may lead to cell death1,2.
• Increase anti-oxidants action in the skin to combat the generation of free radicals, molecules that contribute to aging and cell death3-6.
• Interact with the skin microbiome, or skin bacteria populations, to decrease the overproduction of bacteria that may cause infections or swelling around skin pores8.
• Decrease the activity of sebocytes, cells that are known to contribute to the over production of skin oil in acne9.
