My skin often gets so patchy and dry that even my trusty drugstore lotions just don’t cut it. So, I spent the next 30 days putting body oils up against my favorite lotions. What I found out completely changed how I approach dryness on my body, and it might just change yours too.

Why Your Moisturizer Isn’t Working

Body lotions and body oils contain ingredients that create a layer on the skin to prevent transepidermal water loss. When skin doesn’t have enough water content, it’s what causes the tight feeling and visible flaking.

Most people apply lotion expecting miracles without knowing what their skin actually needs. Sure, lotions provide hydration, but here’s the catch: if your barrier is already compromised, the water can evaporate quickly. This is where the difference between lotion and oil becomes important for dry skin sufferers.

Body Lotions

Lotions are lightweight and fast-absorbing, which makes them a good choice to apply in the morning. The ability to get dressed while the product sinks in is a relief on busy mornings. Additionally, lotions are mostly emollient and partly water-based, which gives skin a basic level of hydration.

Some lotions often contain hyaluronic acid and ceramides, which help maintain skin moisture over time. They can be used on all skin types, making them a safe starting point for anyone unsure about their skin’s needs.

Body Oil

Body oil, on the other hand, has only oil in it. They are highly occlusive and create a physical barrier over the skin to prevent water loss. Unlike lotions, they do not add water to the skin; they only seal in what’s already there to strengthen the lipid barrier of the skin.

I was amazed to know how oil interacts with the body. Apparently, when you apply oil, the top layer of the skin treats these oils as its own and gives a moisturizing effect. Oils like argan, squalane, and jojoba are somewhat similar to the natural lipids present in our skin.

This is why the skin feels instantly supple and more elastic after body oil application. Besides, it leaves the skin glowing, as it remains on the surface layer, giving a dewy finish. Needless to say, it’s temporary, as long as you have oil on the skin.

Molecular Differences That Matter

Lotions penetrate deeper and deliver ingredients to the upper layers of the skin where they are needed most. Body oils work primarily as occlusives and emollients.

Occlusive means they create a barrier, and emollients fill the spaces between skin cells with fatty substances called lipids, thus softening cracked skin.

Since body oil is thicker than lotion, they don’t spread as easily and may have a harder time getting into those cellular spaces, which is why application time matters.

My 30-Day Experiment

I divided my body into test zones for a month. On my left leg, I used only a body lotion. It had hyaluronic acid and ceramides. On my right leg, I applied body oil. I chose squalane oil as it is largely non-comedogenic.

Week one was fine. The lotion side immediately felt smoother after application, but by the next morning, the tightness and dryness came back.

The oil side felt slippery after application, and I had to wait before getting into my clothes, but by day three, the oil side maintained its softness. Flaking was more improved than the lotion-only side.

I saw great results when I started applying on damp skin. I would gently pat dry and apply lotion and oil to damp skin. Towards the end of the 4th week, my chronically dry legs on the oil side were smoother. The lotion side did hydrate, though, but it wasn’t that dramatic.

How Lotion and Oil Work on Different Skin Types

Dry skin: If your skin is extremely dry and cracked, body oils are good for you due to their moisture and barrier-sealing properties that many options often fail to provide. Currently, I’m using Biossance 100% sugarcane squalane oil, and it has single-handedly done a good job on my compromised skin. You can even apply it on your face.

Oily skin: For oily skin, non-comedogenic options like squalane oils are a good choice.

Combination skin: For combination skin, fragrance-free and minimal-ingredient lotion–oil combinations work best. Lotions with soothing ingredients such as colloidal oatmeal or aloe vera are gentle. Avoid formulas with harsh ingredients, as they will further compromise the barrier.

Normal skin: For daily hydration, a lightweight body lotion is enough. If you want extra glow and supple skin, adding oils a few times weekly or even monthly will provide it.

A Practical Cost Breakdown

Here is my honest financial breakdown. Body oils are more expensive upfront; however, their rich concentration means you need far less product. A 3 oz bottle went down by just a quarter after a month of application on my legs and arms.

Lotions are less expensive, but you require more product per application, and daily use is needed. You might run out of lotion quickly, especially if you have extremely dry skin. I personally like a combination approach: first apply lotion, then layer it with an oil.
