How CBG & CBD Penetrate Skin: The Science Behind Gold Naturals Muscle + Joint Salve

Most people understand how CBD works when you swallow it — it enters your digestive system, gets absorbed into the bloodstream, and travels to where it's needed. But what about rubbing it on your skin? How does CBD or CBG actually get from the surface of your skin into the muscle and joint tissue underneath it?

The answer involves some fascinating skin biology — and it's the science that guided the formulation of the Gold Naturals Muscle + Joint Salve.

The Skin: A Sophisticated Barrier (That Isn't Impenetrable)

Your skin is the body's largest organ, and its outermost layer — the stratum corneum — is designed to keep things out. It's a tightly packed layer of dead skin cells embedded in lipid (fat) molecules that form a near-waterproof seal.

Here's where cannabinoids have a natural advantage: CBD and CBG are lipophilic — they dissolve in fats, not water. This means they can actually pass through the lipid layers of the skin far more effectively than water-soluble compounds. They slip through the same lipid channels the skin uses to maintain itself.

Once through the stratum corneum, cannabinoids can reach:

• The dermis — the living tissue layer beneath the surface
• Subcutaneous tissue — the fat layer below the dermis
• Local muscle and connective tissue directly beneath the application site
• Local CB1 and CB2 receptors found in skin cells, nerve endings, and immune cells

Importantly, topical cannabinoids typically do not reach the bloodstream in significant concentrations — they act locally. This is actually an advantage for targeted muscle and joint relief: the effect goes where you put it, without systemic effects.

CBG in a Topical: Why It Matters

CBG's CB2 receptor activity becomes particularly relevant in a topical format (Navarro et al., 2018). CB2 receptors are abundant in skin tissue — especially in immune cells called mast cells and keratinocytes — and they play a direct role in regulating local inflammation (Maccarrone et al., 2015).

When CBG is applied topically at the site of soreness or inflammation:

1. It penetrates the lipid layers of the skin
2. It binds to CB2 receptors in local immune and skin cells
3. It activates anti-inflammatory signaling pathways locally
4. It may inhibit the release of pro-inflammatory cytokines at the application site

This local action is what makes a well-formulated topical salve a genuinely different product category — not just CBD lotion, but a targeted cannabinoid delivery system.

The Gold Naturals Muscle + Joint Salve: How It's Made

The Gold Naturals Muscle + Joint Salve was developed in close collaboration with our manufacturing and scientific partners. The formulation is built around several key principles:

• Full-spectrum hemp extract — delivering CBG, CBD, and complementary cannabinoids together for entourage effect at the site of application
• Lipid-rich base — chosen specifically to enhance cannabinoid penetration through the stratum corneum
• Complementary botanicals — ingredients selected to support circulation and tissue response at the application site
• No artificial fragrances or harsh chemicals — clean formulation designed for sensitive or compromised skin

How to Use the Salve for Best Results

For optimal topical absorption:

• Apply to clean, dry skin — residue from other products can block absorption
• Use a generous amount and massage in thoroughly — friction helps drive penetration
• Apply directly to the site of discomfort, not adjacent areas
• Allow 10–15 minutes before covering with clothing — gives the lipid base time to penetrate
• Reapply as needed, 2–4 times daily

The Science of Topical Cannabinoids: What Our Advisor Says

Advisors trained in the tradition of Dr. Raphael Mechoulam, Gold Naturals' Chief Scientific Advisor — who conducted postdoctoral research under Professor Raphael Mechoulam at the Hebrew University of Jerusalem — notes that the lipophilic nature of cannabinoids makes them particularly well-suited to topical delivery:

"The endocannabinoid system has significant peripheral representation — including in skin, muscle, and connective tissue. Topical cannabinoid delivery directly targets these peripheral receptors, making it a rational and promising approach for localized relief."
