If you have spent any time online lately, you have probably heard someone tell you to avoid seed oils.

They have been blamed for everything from inflammation to chronic disease, and the conversation has become so widespread that it is beginning to influence how people view the same ingredients in their skincare products.

But there is an important distinction that often gets lost:

How an ingredient interacts with the digestive and metabolic systems when consumed is fundamentally different from how a properly formulated cosmetic ingredient interacts with the outer layers of the skin.

So, before you throw away a body care product because you spotted the words sunflower seed oil or jojoba seed oil on the ingredient list, it is worth looking at what the dermatological research actually says.

First, What Exactly Is a Seed Oil?

Seed oils are oils extracted from the seeds of plants. Sunflower, safflower, grapeseed and jojoba are familiar examples, although their individual chemical compositions can vary considerably.

From a skincare perspective, that composition matters.

Plant oils contain different proportions of fatty acids along with compounds such as tocopherols, phytosterols and other naturally occurring components. Those differences help determine how an oil behaves when it is applied to the skin.  (Lin et al., 2018; Poljsak & Kocevar Glavac, 2022)

That distinction is important.

The Seed Oil Debate: Eating Them vs. Putting Them on Your Skin

Much of today's seed oil controversy centers on dietary intake and the way different fats are discussed in nutrition conversations.

Whether someone chooses to consume certain oils is a nutritional question. Topical skincare is a different route of exposure with a different purpose.

When plant oils are applied topically, researchers have studied their effects on the stratum corneum, the outermost layer of the skin, including their relationship to moisture retention, barrier function and inflammation. A dermatological review notes that topical plant oils can have localized effects on the skin, and many largely remain within the surface and upper layers rather than behaving as they would after digestion.  (Lin et al., 2018)

That means it is misleading to take an argument about cooking oil and automatically apply the same conclusion to a professionally formulated skincare product.

Your Skin Actually Needs Lipids

Your skin barrier is not simply a layer of dead skin. Lipids are an essential part of its structure and its ability to limit excessive water loss.

This is where fatty acids become particularly interesting.

Stearic acid is a saturated fatty acid naturally present in the skin's surface lipids and in many seed-derived oils and butters. It is especially notable in mango seed butter and shea butter, where it helps contribute to the rich, cushiony texture that makes these ingredients useful in moisturizers.  (Ananthapadmanabhan et al., 2013; Di Vincenzo et al., 2005; Maldonado-Celis et al., 2019)

A dermatology and cosmetic-science review explains that free fatty acids, including stearic acid, are part of the lipid matrix that supports the stratum corneum. The review describes the rationale for using stearic acid in moisturizing cleansers to help reduce fatty-acid loss during washing and replenish lipids associated with barrier preservation.  (Ananthapadmanabhan et al., 2013)

A 2022 scientific review examined 27 clinical studies involving 17 vegetable oils and found that their effects depend on the complete oil, the condition of the skin, and how frequently and for how long the product is used.  (Poljsak & Kocevar Glavac, 2022)

That is a much more nuanced picture than simply saying, "seed oils are bad."

What Dermatology Research Says About Stearic Acid

Stearic acid is not a trendy standalone cure. Its value is best understood as one part of a well-designed skincare formula.

Because it is a long-chain saturated fatty acid, stearic acid can contribute structure, slip and emollience to creams and body-care products. It is also one of the free fatty acids found within the organized lipid environment of the stratum corneum.  (Ananthapadmanabhan et al., 2013)

Mango seed fat and shea butter naturally contain meaningful amounts of stearic acid, although the exact percentage varies with plant variety, origin and processing. That natural variation is another reason to evaluate the finished formulation rather than making broad assumptions from a single ingredient name.  (Di Vincenzo et al., 2005; Maldonado-Celis et al., 2019)

This does not mean every seed-derived ingredient is perfect for every person or that more is always better. It demonstrates why evaluating an ingredient by its actual composition, concentration and formulation makes more sense than rejecting it simply because it came from a seed.

Oils Can Help Support Moisture Retention

One of the primary reasons botanical oils are used in body care is beautifully simple: dry skin needs help retaining water.

The American Academy of Dermatology explains that skin becomes dry when it loses too much water. Dermatologists recommend moisturizers to help combat that water loss and note that creams and ointments generally hold more moisture in the skin than lighter lotions.  (American Academy of Dermatology, 2026)

The AAD even lists jojoba oil among ingredients consumers can look for in creams and ointments when addressing dry skin.  (American Academy of Dermatology, 2026)

There is also a technique component. Applying moisturizer while the skin is still slightly damp after bathing helps trap water in the skin before it evaporates.  (American Academy of Dermatology, 2026)

That is why a body oil can be especially useful immediately after a shower or layered with a body cream.

Not All Plant Oils Behave the Same Way

This is where skincare formulation matters.

Natural does not automatically mean appropriate for every skin type, and every botanical oil does not produce the same effect.

Research suggests that fatty-acid composition, extraction method, concentration and the condition of the skin can all influence how a plant oil behaves. Even two oils that share some of the same fatty acids can feel and perform differently because their complete chemical profiles are not identical.  (Lin et al., 2018; Vaughn et al., 2018; Poljsak & Kocevar Glavac, 2022)

That nuance aligns with one of the principles behind Embellish Skin Care: an ingredient should earn its place in a formula.

We do not believe an ingredient is beneficial simply because it is natural. We look at what an ingredient contributes to the formula and the experience we want that formula to deliver.

Botanical Oils in the Embellish Routine

Plant-derived oils are incorporated throughout the Embellish Skin Care collection as part of thoughtfully developed formulas designed to nourish, condition and help maintain soft, moisturized skin.

 

 

Botanical Oils Across Embellish

Our ingredient philosophy extends beyond a single seed oil. Embellish formulas use a selection of plant-derived ingredients including jojoba seed oil, avocado oil, sweet almond oil, moringa oil, coconut oil and mango seed butter, among other botanicals.  (Embellish Skin Care Ingredient List)

Each brings its own fatty-acid profile, texture and functional characteristics to a formulation.

That variety is intentional. Skincare is not about finding one trendy ingredient and putting it into everything. It is about understanding how ingredients work together.

So, Should You Avoid Seed Oils in Skincare?

Based on the available dermatological research, there is no scientific basis for treating every topically applied seed oil as inherently harmful simply because it is a "seed oil."

A better question is:

The research surrounding botanical oils is still evolving, and not every claimed benefit has the same level of clinical evidence. Individual sensitivities are also possible with botanical ingredients, just as they are with many cosmetic ingredients.

But the current evidence gives us good reason to separate the social-media conversation surrounding dietary seed oils from the science of topical skincare.

The Bottom Line

Your cooking oil and your body oil are not interchangeable conversations.

When used appropriately in skincare, certain seed-derived and botanical oils can provide fatty acids and emollient properties that help condition the skin, support moisture retention and, depending on their composition, contribute to healthy skin-barrier function.

So when you see sunflower seed oil or jojoba seed oil on a skincare label, do not let the word "seed" make the decision for you.

That is the difference between ingredient fear and ingredient literacy.

At Embellish Skin Care, we believe you deserve the latter.
