The dewy, healthy, no-makeup look continues to be beauty’s biggest trend as we look toward 2023. And there’s great news: getting your most radiant skin ever doesn’t require a trip to the dermatologist, or even your esthetician. It’s 100 percent achievable in the comfort of your own bathroom. The secret: deep hydration courtesy of the right moisturizer and facial oil.

While many people view these two products as interchangeable, there are several key differences between moisturizers vs. facial oils. So if you’re wondering whether face oil can replace moisturizer, the answer is a resounding no. Read on to get the science behind moisturizers vs. face oils, how to use them, and why you need both.

What’s the difference between moisturizers vs. facial oils?

Understanding the difference between moisturizers and facial oils requires a deeper knowledge of skin types. Specifically, it’s important to know the difference between dry and dehydrated skin. Fortunately, it’s not that complicated.

All of our organs need water to function properly, and your skin is no different. Think of your skin like a piece of fruit. When fruit is fresh, it’s plump and juicy with smooth, taught skin. Now think of a piece of dehydrated fruit. It’s creased and deflated with skin that appears wrinkled. When your skin needs water, its appearance is affected in a similar way. 

This is why moisturizers are typically water-based; they’re formulated to replenish the skin’s water content, both on the surface and in its deeper layers. They may also contain ingredients such as hyaluronic acid which pull more water into the skin. As a result of the added water content, your skin instantly plumps up, smoothing fine lines and wrinkles.

As we all know, oil and water don’t mix, so facial oils neither contain water, nor do they add water back into the skin. Their main function is to repair and protect the skin’s moisture barrier (the skin’s natural protective layer) while adding nourishment. They work like vitamin-rich plastic wrap, sealing in moisture to keep it from evaporating out of the skin. In other words, facial oils don’t add water, they retain it.

In a nutshell: moisturizers provide instant hydration, while oils seal, protect, and nourish.

Can face oil replace moisturizer?

Many people make the erroneous assumption that face oil can replace moisturizer because it’s so rich and emollient. But because face oil adds nourishment and seals in moisture, using it alone is like eating food without drinking water. You’ll get by, but your skin won’t be adequately hydrated.

Almost all skin types benefit from using both moisturizer and facial oils together. When you pair a water-based moisturizer with a nourishing, non-comedogenic facial oil (such as our sugarcane-derived squalane), you’re ensuring that your skin stays hydrated and nourished all day long. This also helps to fortify the moisture barrier, helping ward off the damaging effects of environmental stressors such as bacteria and pollution. 

The result: healthy, hydrated, skin that appears plumper, smoother, and more radiant.

    As a lifestyle writer and journalist, I’m excited to bring my passion for storytelling to Biossance as an Engagement Content Writer. Two things you should know about me: I have a deep love of the ocean (especially sharks) and I’m obsessed with clean beauty. My bathroom cabinet is literally overflowing with my many-layered sustainable skincare routine. This combo is what led me to buy my first bottle of Vitamin C Rose Oil. I was so impressed by the way it improved my skin that I wanted to shout this brand from the rooftops. Three years later, and here I am doing just that. I’m excited to be on this journey of clean beauty innovation with Biossance, and to share it with you here on the blog.
