Your Biggest Organ Is Absorbing Everything You Put On It

We spend a lot of time thinking about what we put in our bodies. We read food labels, think about ingredients, and try to be mindful of what we eat and drink. But how much time do we spend thinking about what we put on our bodies?

Your skin is your largest organ. It covers roughly 22 square feet on the average adult and accounts for about 15% of your total body weight. And it’s not just a wrapper. It’s alive, it’s active, and it’s absorbing. Whatever you put on it doesn’t just sit on the surface — a significant amount of it makes its way into your bloodstream.

Which means the lotion you rub on every day, the perfume you spray, the body wash you use — those aren’t just cosmetic choices. They’re health choices. And most of us have never thought about it that way.

Why Moisturizing Matters More Than You Think

Your skin has a natural protective barrier called the lipid barrier — a thin layer of oils and fats that sits on the outermost layer of your skin. This barrier does two critical things: it keeps moisture in, and it keeps harmful substances out. When that barrier is healthy, your skin stays hydrated, resilient, and better able to protect you.

But that barrier breaks down. Dry air, hot showers, harsh soaps, sun exposure, aging, and environmental pollutants all strip it away over time. When the lipid barrier is compromised, your skin loses water faster than it can replace it. That’s when you get dryness, cracking, irritation, sensitivity, and even accelerated aging. On a deeper level, a weakened skin barrier also means your skin becomes more permeable — meaning it absorbs what you put on it more readily.

Moisturizing isn’t just about making your skin feel soft. It’s about restoring that barrier, helping the skin retain water, and keeping the whole system functioning the way it should.

The Problem with Most Products on the Shelf

Here’s where things get uncomfortable. Many conventional lotions, body washes, and perfumes contain ingredients that have no business being on your skin — let alone in your bloodstream. Parabens, phthalates, synthetic fragrances, formaldehyde releasers, and oxybenzone are just a few of the common offenders. These ingredients are used as preservatives, stabilizers, or fragrance enhancers, and many of them have been flagged by researchers for their potential to disrupt hormones, irritate the skin, and accumulate in the body over time.

A 2019 study published by the FDA found that common chemical sunscreen ingredients were absorbed into the bloodstream at levels exceeding safety thresholds after just a single day of use. And that’s just sunscreen. Now multiply that by every lotion, perfume, deodorant, and body product you use daily — the cumulative load adds up.

The skin doesn’t have a filter. It doesn’t sort out the good from the bad. It absorbs what’s there. Which is exactly why what you choose to put on it matters.

A Better Option

This is one of the reasons we love dōTERRA’s SPA Hand & Body Lotion. It’s formulated without parabens, phthalates, or synthetic fragrances — and the ingredient list reads like something you’d actually want on your skin.

The base is built on plant-derived oils and butters that work with your skin’s natural chemistry. Jojoba seed oil is uniquely similar to your skin’s own sebum, so it absorbs easily without clogging pores and helps balance oil production naturally. Macadamia seed oil is rich in palmitoleic acid — a fatty acid that naturally occurs in human skin but decreases with age — making it especially beneficial for restoring suppleness and elasticity. Murumuru seed butter and theobroma (cocoa) seed butter provide deep, lasting moisture and form a gentle barrier that helps prevent water loss. And sunflower seed oil and coconut oil round out the formula with essential fatty acids and vitamin E to nourish and protect.

The lotion is also intentionally lightly scented, which means you can add your own essential oils and customize it however you like. A few drops of Lavender for calming. Wild Orange for a mood lift. Frankincense for a more luxurious skin experience. It becomes yours.

Or Just Keep It Simple

If you want the most stripped-down version of clean moisturizing, you can’t go wrong with plain coconut oil. It’s naturally rich in lauric acid (which has antimicrobial properties), it absorbs well into the skin, and it acts as an effective barrier to prevent moisture loss. It’s affordable, it’s widely available, and you know exactly what’s in it — because there’s only one ingredient.

A jar of organic, unrefined coconut oil in the bathroom is one of the simplest swaps you can make. Use it after the shower while your skin is still damp, and it locks in hydration beautifully. You can also mix in a drop or two of essential oil for scent and added benefit.

We wouldn’t eat something without checking the ingredients. Our skin deserves the same consideration. It’s not just what we put in our bodies that matters — it’s what we put on them. And when we choose products that are clean, simple, and designed to work with our biology instead of against it, we’re making a decision that our body feels at every level.
