Before You Buy Another Serum: The Bioactives Already in Your Facial Oil

This article is for cosmetic skincare education and is not medical advice. Always consult a qualified healthcare provider for medical concerns.

Walk into any skincare aisle — or scroll through any beauty feed — and you'll find serums promising niacinamide, vitamin C, squalane, CoQ10, vitamin E, and bakuchiol. Each one marketed as a must-have addition to your routine.

But if you're already using a well-formulated botanical facial oil, you may be surprised how many of these "trending" bioactives are already present — naturally — in the oils you're applying every day.

This isn't a case against serums. It's a case for understanding what you already have.

What Are Bioactives?

Bioactives are compounds found in plants that have a recognized effect on the skin's appearance, feel, or surface condition. In skincare, they're the compounds that go beyond basic moisturization — antioxidants, tone-supporting compounds, texture refiners, and barrier-comfort enhancers.

The skincare industry has largely built its serum category around isolating and concentrating individual bioactives. But botanical oils have always contained them — in their naturally occurring, lipid-soluble form, alongside the fatty acids and phytosterols that help them integrate with skin's surface lipids.

To understand how oils and serums relate, it helps to think in three categories: bioactives that oils contain, water-soluble actives that oils complement, and a hybrid category that lives in the oil phase by design.

Part One: The Lipid-Soluble Bioactives Already in Your Oil

These are the trending serum ingredients that botanical oils naturally contain — in their whole-plant, lipid-compatible form.

Vitamin E (Tocopherols & Tocotrienols)

Vitamin E serums are perennial bestsellers. What most labels don't tell you is that tocopherols exist as a family — alpha, gamma, and delta tocopherols, plus tocotrienols — and each fraction has distinct antioxidant behavior.

In isolated serums, you typically get one form, usually alpha-tocopherol. In botanical oils, you get the whole family. Cranberry seed oil is particularly notable: it delivers alpha, gamma, AND delta tocopherols plus tocotrienols — a tocopherol breadth rarely matched by any single-source serum. You'll find it in Radiant Renewal Facial Oil.

In botanical oils, tocopherols also serve a dual function: they protect the oil itself from oxidation and deliver antioxidant benefits to the skin's surface simultaneously.

Squalane

Squalane serums have surged in popularity as a lightweight, sebum-compatible moisturizer. Lab-derived squalane (typically from sugarcane or olives) is hydrogenated for shelf stability and a very light feel. Both Luna Luxe and Radiant Renewal include plant-derived squalane directly in the formula — a breathable, non-comedogenic surface feel that works with your skin's natural lipid environment.

Bakuchiol

Bakuchiol has become one of the most talked-about actives of the last three years, positioned as a plant-based alternative to retinoids for the appearance of smoother, more refreshed-looking skin — without the photosensitivity or irritation concerns.

What makes bakuchiol different from most "trending" actives is that it only comes from one source: the seed of Psoralea corylifolia. It cannot be approximated by another oil. Both Luna Luxe Night Facial Oil and Radiant Renewal Facial Oil are formulated with bakuchiol oil as a botanical active — not a background ingredient.

Carotenoids (Beta-Carotene, Lycopene, Zeaxanthin)

Carotenoid-rich serums are increasingly marketed for a more radiant, luminous-looking complexion. Sea buckthorn seed oil is one of the most carotenoid-dense cosmetic oils available — rich in beta-carotene, lycopene, and zeaxanthin. Rosehip fruit oil contributes beta-carotene and lycopene alongside its high polyunsaturated fatty acid content. Avocado oil adds beta-carotene and lutein. These carotenoids are present in their naturally occurring, lipid-soluble form — the same form in which they're most compatible with the skin's own lipid matrix. Both Luna Luxe and Radiant Renewal contain sea buckthorn seed oil.

Phytosterols — The Bioactive Most Serums Don't Mention

Here's one your serum likely doesn't feature: phytosterols. These plant-derived lipid compounds are found throughout botanical oils — sitosterol, campesterol, and stigmasterol in most oils, and uniquely schottenol and spinasterol in argan oil specifically. Phytosterols are structurally analogous to cholesterol and are a natural component of the skin's intercellular lipid matrix.

They're not trending yet. But they may be the most skin-compatible bioactives in botanical oils — and one of the reasons a well-formulated facial oil can feel so immediately comfortable from the very first application.

Polyphenols — The Deep Antioxidant Layer

The polyphenol category is where botanical oils genuinely outperform most single-active serums in terms of complexity:

• Silymarin (milk thistle) — a flavonolignan complex including silibinin, rarely seen in cosmetic formulas; found in our Vitamin C Facial Oil
• Ellagic acid and ellagitannins — found in pomegranate seed and red raspberry seed oils; both in Luna Luxe and Radiant Renewal
• Proanthocyanidins — from cranberry seed oil in Radiant Renewal
• Ferulic acid — naturally present in argan oil (Luna Luxe) and rice bran oil (Luna Luxe); ferulic acid is also widely used as a vitamin C stabilizer in premium water-based serums

No single serum delivers all of these. Your facial oil already does.

Rare & Differentiating Lipid Bioactives

A few bioactives in our formulations have no mainstream serum parallel — which is precisely what makes them worth naming:

• Punicic acid (omega-5 conjugated linolenic acid) from pomegranate seed oil — a rare conjugated triene fatty acid found in very few cosmetic oils; present in both Luna Luxe and Radiant Renewal
• Very long-chain fatty acids (C20–C40: nervonic, ximenic, gadoleic) from ximenia oil — found almost nowhere else in cosmetic formulation; contribute to the rapid absorption and lightweight cushion of the Vitamin C Facial Oil
• Erucic acid (C22:1) from abyssinian oil — provides exceptional slip and oxidative stability with a weightless, silicone-like finish
• Behenic acid (C22:0) from moringa oil — a conditioning long-chain fatty acid that contributes to moringa's distinctive velvety skin feel
• Omega-7 (palmitoleic acid) from sea buckthorn — a fatty acid naturally present in human sebum that supports a nourished, comfortable skin feel
• Gamma-oryzanol from rice bran oil — a unique complex of ferulic acid esters and sterols found almost exclusively in rice bran; an emerging phytoactive with limited mainstream presence

Part Two: The Water-Soluble Actives That Layer With Your Oil

These are the trending serum ingredients that botanical oils don't contain — because they're water-soluble. But this isn't a gap; it's a relationship. Your oil provides the lipid environment that helps these actives perform.

Niacinamide (Vitamin B3)

Niacinamide is water-soluble and not present in carrier oils. However, niacinamide works synergistically with barrier lipids — it's often paired with ceramides and fatty acids in formulations precisely because the lipid environment supports its performance. A high-linoleic botanical oil applied after a niacinamide serum provides exactly the fatty-acid-rich barrier context that complements niacinamide's skin-feel benefits. Apply serum first, oil second.

Hyaluronic Acid & Polyglutamic Acid

Oils don't provide humectants — but they supply the occlusive and emollient lipids (oleic acid, linoleic acid, squalane, phytosterols) that help slow moisture loss and support the comfortable skin feel that humectant serums create. Apply your humectant serum first, then seal with oil.

Panthenol (Provitamin B5)

Panthenol works synergistically with the tocopherols and phytosterols naturally present in botanical oils. The oil contributes emollient cushion and antioxidant protection that complements panthenol's skin-feel benefits — a natural pairing in a layered routine.

Azelaic Acid

Azelaic acid is typically delivered in oil- or ester-rich bases where linoleic and oleic acids plus tocopherols help moderate skin feel and support barrier comfort. Lightweight, linoleic-rich oils like those in our formulations are a natural complement — apply azelaic first, seal with oil.

Part Three: The Hybrid Category — Actives That Live in the Oil Phase

Vitamin C — The One That Requires Nuance

Traditional vitamin C (ascorbic acid) is water-soluble. It's not present in carrier oils, and botanical oils are not a substitute for a vitamin C serum if you're seeking its specific appearance benefits.

However, the lipid-soluble form — tetrahexyldecyl ascorbate (THD ascorbate) — integrates directly into an oil formula. It's significantly more stable than ascorbic acid and fully compatible with the fatty acid matrix of carrier oils.

Our Vitamin C Facial Oil uses THD ascorbate at 3% in a base of three carefully chosen specialty oils:

• Milk thistle seed oil — high-linoleic, rich in the silymarin polyphenol complex (flavonolignans including silibinin); a bioactive you won't find in mass-market formulas
• Ximenia oil — sourced from wild-harvested African ximenia trees; contains very long-chain fatty acids (C20–C40) found almost nowhere else in cosmetic ingredients
• Abyssinian oil — cold-pressed from Crambe abyssinica seeds; ~50–65% erucic acid, delivering exceptional slip and oxidative stability with zero greasiness

The result: oil-soluble vitamin C in a barrier-supportive lipid matrix, with no water phase, no destabilizing aqueous environment, and no unnecessary fillers.

So Do You Need Serums?

It depends on what you're looking for. Here's a quick reference:

Bioactive	In Botanical Oils?	Recommendation
Vitamin E (tocopherols)	Yes — broad spectrum	Botanical oil may be sufficient
Squalane	Yes — in formula	Botanical oil covers this
Bakuchiol	Yes — as a formulated active	Luna Luxe & Radiant Renewal have it
Carotenoids (beta-carotene, lycopene)	Yes — rosehip, sea buckthorn	Botanical oil covers this
Phytosterols	Yes — in every formula	Botanical oil covers this
Polyphenols	Yes — broad spectrum	Botanical oil covers this
Lipid-soluble Vitamin C	Yes — in Vitamin C Facial Oil	Our oil covers this
Niacinamide	No — water-soluble	Layer a niacinamide serum underneath
Water-soluble Vitamin C	No	Use a dedicated serum, then oil on top
Hyaluronic acid / Panthenol	No — water-soluble	Apply first, seal with oil

The honest answer: a thoughtfully formulated botanical oil already delivers more bioactive complexity than most people realize. For many skin types, it's a complete lipid-phase routine on its own. Where water-soluble actives like niacinamide or ascorbic acid matter to you, apply them first on clean skin — and let your oil seal and support everything that follows.

What's in Our Formulations

Every oil in our collection is built around this principle: bioactive complexity, not a single hero ingredient.

• Radiant Renewal Facial Oil — Bakuchiol + antioxidant berry seed oils (cranberry, raspberry, pomegranate, sea buckthorn) + rosehip carotenoids + squalane. The broadest polyphenol and tocopherol stack in our lineup, designed for a more radiant, even-looking complexion. Ideal for oily-to-normal, combination, and brightening-focused skin types.
• Luna Luxe Night Facial Oil — Bakuchiol + pomegranate seed (punicic acid/omega-5) + moringa (behenic acid conditioning) + sea buckthorn (omega-7 + carotenoids) + argan (rare schottenol and spinasterol phytosterols) + gamma-oryzanol from rice bran + squalane. The deepest barrier-comfort and nourishing lipid stack in our lineup, designed for dry, mature-feeling skin and evening skincare routines.
• Vitamin C Facial Oil — Tetrahexyldecyl ascorbate (3%) + milk thistle (silymarin flavonolignans + high-linoleic base) + ximenia (rare C20–C40 very long-chain fatty acids) + abyssinian (erucic acid slip and stability). Four premium ingredients. No fillers. The only oil-phase vitamin C formula in our collection.

The Bottom Line

The serum industry has done an excellent job of isolating individual bioactives and marketing them as essential additions to your routine. Many of them genuinely are. But botanical facial oils have always contained a broad spectrum of these same compounds — in their naturally occurring, lipid-soluble form, alongside the fatty acids and phytosterols that make them skin-compatible.
