Your Skin Is Your Largest Organ: So Why Aren't We Treating It That Way?

When I began my wellness journey and started researching the effects of food on our major organs, I realized we often overlook our biggest one, our skin. We know that what we put into our bodies shows up in our skin, whether that is dull and dry or bright and vibrant. But the inverse is equally true: what we put on our skin gets absorbed into our bodies and can negatively affect our internal organs. That realization changed everything about how I approached skincare for my family.

The Basics: What Your Skin Actually Does

Your skin is the largest organ in your body, covering roughly 22 square feet in the average adult and accounting for about 15% of total body weight. It is not just a wrapper. It is a living, active system with multiple critical functions:

• Barrier protection — keeps pathogens, toxins, and environmental stressors out
• Temperature regulation — manages heat through sweat and circulation
• Immune surveillance — contains specialized immune cells that detect and respond to threats
• Vitamin D synthesis — converts sunlight into a hormone essential for bone health, immune function, and mood
• Absorption — takes in substances from the external environment and transports them into the body

That last function is the one that changes how you think about skincare.

Your Skin Absorbs What You Put On It

Transdermal absorption which is the process by which substances pass through the skin and enter the bloodstream. This process is well-documented in medical research. It is, in fact, the basis of numerous pharmaceutical treatments: nicotine patches, hormone therapy patches, pain relief patches. Medicine uses the skin as a delivery system precisely because it works.

The degree of absorption depends on several factors, including the molecular size of the substance, the area of skin exposed, and the health of the skin barrier. But the core fact remains: what goes on your skin does not simply stay there.

Studies have detected common skincare ingredients including parabens, phthalates, and synthetic fragrances, in blood and urine samples after topical application. The Environmental Working Group has documented over 1,400 chemicals banned or restricted in cosmetics in the European Union that remain legal and in use in the United States.

The Ingredients Worth Knowing About

You do not need to memorize a chemistry textbook. But a few categories of ingredients are worth understanding because they appear in the vast majority of conventional skincare and personal care products:

Parabens

Parabens (methylparaben, propylparaben, butylparaben) are preservatives used in an estimated 85% of cosmetics. They are endocrine disruptors meaning they mimic estrogen in the body. Research has detected parabens in breast tissue samples, and studies have linked paraben exposure to hormonal disruption, particularly in developing children.

Synthetic Fragrance

"Fragrance" on an ingredient label is a legally protected trade secret that can represent a blend of hundreds of undisclosed chemicals. Common fragrance compounds include phthalates, which are linked to endocrine disruption and reproductive harm. Good to know fact, a product labeled "unscented" is not the same as fragrance-free. Unscented products often contain masking fragrances.

Mineral Oil and Petrolatum

Derived from petroleum, these ingredients are among the most common in conventional moisturizers. They work by forming an occlusive layer on top of the skin that prevents water loss but they do not contribute any nutrients, repair any damage, or support skin biology in any active way. Highly refined versions are considered safe, but they are also entirely inert. Your skin gets nothing from them except a temporary surface coating.

PEGs (Polyethylene Glycols)

PEGs are used as emulsifiers, thickeners, and penetration enhancers in skincare. Their role as penetration enhancers is particularly notable as they help other ingredients absorb more deeply into the skin, which is useful when those other ingredients are beneficial, and concerning when they are not.

The Cumulative Load Problem

Individual ingredients are rarely tested in combination. But the average adult uses between 9 and 15 personal care products daily, resulting in exposure to over 100 unique chemical ingredients before leaving the house in the morning. Regulatory safety assessments evaluate ingredients in isolation. They do not account for the compounding effect of daily, multi-product exposure over months and years, particularly in children, whose developing endocrine and immune systems are significantly more vulnerable to chemical interference.

What This Means for How You Choose Skincare

It means the standard for skincare should be the same as the standard for food: know what is in it, know where it came from, and make sure every ingredient has a reason to be there.

Our products exist at the far end of that spectrum. Every ingredient we use, tallow, honey, salt etc., is pure, ancestral, and edible. Known sources, no synthetic additives, no preservatives, no fillers. Nothing your skin cannot recognize and use. That is the standard every product we make is held to.

This is not about fear. It is about making an informed choice, the same way you do at the grocery store.

For me, the first ingredient that stopped me cold was sodium lauryl sulfate aka SLS. It is in almost everything, including most toothpastes, and once I understood what it was doing I could not un-know it. Once I realized I could make my own products that were genuinely safe and effective, I was all in. I would rather cheat with a piece of cake than poison myself through my skincare.

The Bottom Line

Your skin is not a barrier between you and the world it is a gateway. What you put on it matters. Treating your skin with the same care and intentionality you bring to what you eat is not an extreme position. Given what the research shows about absorption, endocrine disruption, and cumulative chemical exposure, it may be the most rational one.

I am committed to building a brand that holds the same standard for your family that I hold for my own pure, safe, and nothing we would not put on our own skin. That commitment does not have an asterisk. It does not change based on trends, cost, or convenience.
