Do Face Oils Really Work? Here’s the Science

Do Face Oils Really Work? Here’s the Science

Face oils have earned a devoted following in the skincare world — but they’ve also sparked a fair share of skepticism. Some people swear by them for achieving glowing, hydrated skin, while others worry that oils might clog pores, cause breakouts, or just sit on the skin without doing much at all.

So, what’s the truth? Do face oils actually do anything for your skin? Or are they just another beauty trend?

Let’s break it down — with science, not hype — and take a closer look at what face oils are, how they work, and why they may (or may not) deserve a place in your routine.


What Are Face Oils?

Face oils are typically cold-pressed, plant-based oils derived from seeds, nuts, fruits, or flowers. They are rich in:

  • Essential fatty acids (like linoleic and oleic acid)

  • Antioxidants (like vitamins A, C, and E)

  • Anti-inflammatory compounds (like polyphenols and flavonoids)

Some oils are occlusive, meaning they create a barrier to lock in moisture, while others are more emollient, helping to soften, soothe, and smooth the skin’s surface.


Myth: “Oils Just Sit on the Skin”

Truth: Face oils can absorb and nourish the skin — but not all oils are created equal.

The key is choosing oils with a low molecular weight and high content of skin-compatible lipids. For example:

  • Rosehip seed oil and cacay oil are rich in linoleic acid and absorb quickly.

  • Marula oil and jojoba oil mimic your skin’s natural sebum.

  • Cloudberry oil and sea buckthorn offer antioxidant protection while moisturizing.

Research shows that these oils don’t just sit on the skin — they actively support the skin barrier, deliver nutrients, and improve hydration [1].


Myth: “Oils Will Clog My Pores”

Truth: Not all oils clog pores — in fact, many plant oils can actually help balance your skin, regulate sebum, and support a healthy microbiome.

The fear of breakouts often comes from heavy, pore-clogging oils like mineral oil or coconut oil, which are high on the comedogenic scale. But oils like Tsubaki, balanites, and rosehip are lightweight, fast-absorbing, and non-comedogenic — meaning they won’t block your pores.

Here’s why some oils help, not hurt:

  • Oily and acne-prone skin tends to be deficient in linoleic acid, a key fatty acid that keeps sebum fluid and less sticky. Oils rich in linoleic acid actually help prevent clogged pores [2].

  • Non-comedogenic oils absorb easily, nourish without suffocating the skin, and deliver anti-inflammatory compounds that calm active breakouts.

Non-pore-clogging, acne-safe oils:

  • Tsubaki Oil (Camellia Japonica)
    A traditional Japanese beauty oil that mimics skin’s natural sebum. Lightweight and rich in oleic acid and antioxidants, it hydrates without heaviness — ideal for sensitive or combination skin types.

  • Balanites Oil (Desert Date Oil)
    A desert-derived oil with a high content of linoleic acid and phytosterols. Its anti-inflammatory, antimicrobialprofile makes it a smart choice for acne-prone or reactive skin.

  • Rosehip Oil – High in vitamin A and linoleic acid; promotes healing and fades discoloration.

  • Squalane (plant-derived) – Non-comedogenic, stable, and similar to your skin’s natural lipids.

  • Hemp Seed Oil – Balances oil production and calms inflammation.

Tip: Always patch test new oils, use just a few drops, and apply them as the last step to seal in hydration — not on dirty skin.


What Face Oils Actually Do for Skin

1. They Seal in Moisture

Face oils are most effective when applied as the final step in your routine (before sunscreen in the morning or after moisturizer at night). That’s because they act as occlusives, helping to:

  • Prevent transepidermal water loss (TEWL)

  • Lock in hydration and water-based serums

  • Protect the skin from environmental stress

Think of oils as a “topcoat” that holds everything in.


2. They Strengthen the Skin Barrier

Many oils are rich in omega-3 and omega-6 fatty acids, which are essential to maintaining a healthy, resilient skin barrier. A strong barrier:

  • Keeps moisture in

  • Keeps irritants and pollution out

  • Reduces inflammation and sensitivity

Oils like cacay, rosehip, tsubaki, and cloudberry are rich in barrier-repairing lipids and antioxidants.


3. They Deliver Antioxidants

Cold-pressed oils are naturally rich in antioxidants like vitamin E, carotenoids, and polyphenols, which help:

  • Fight free radical damage

  • Protect against UV and pollution-related aging

  • Support collagen production and skin healing

For example, cloudberry oil contains vitamin C and beta-carotene, while pomegranate oil is packed with ellagic acid — both of which offer powerful protective benefits [3].


4. They Help Even Skin Tone and Texture

Some oils, like rosehip seed oil, contain trans-retinoic acid, a natural form of vitamin A that helps:

  • Improve cell turnover

  • Fade hyperpigmentation and dark spots

  • Smooth rough texture and fine lines [4]

While these effects are more subtle than prescription retinoids, they’re a gentle, natural alternative that supports skin health over time.


How to Layer Face Oils in Your Routine

Here’s a simple way to incorporate oils — without overdoing it.

Morning:

  • Cleanser

  • Vitamin C serum or niacinamide

  • A few drops of oil (Use as your moisturizer)

  • Sunscreen

Tip: In the morning, oils like cloudberry or jojoba can provide antioxidant support and extra glow under SPF.

Evening:

  • Cleanser

  • Toner or essence

  • Treatment serum (like bakuchiol or peptides)

  • 2–3 drops of facial oil as the final step 

Facial oils help seal in the benefits of everything underneath — and deliver their own nourishment, too.


Who Should Use Face Oils?

Face oils can benefit almost anyone, depending on your skin’s needs. Here’s a quick guide:

Skin Type Recommended Oils
Dry Cacay, marula, sea buckthorn, avocado, Plum kernel
Oily/Acne-Prone Rosehip, hemp seed, tsubaki, balanites
Sensitive Jojoba, calendula, tamanu
Mature Rosehip, pomegranate, cacay,  kakadu plum, Plum Kernel
Dull/Tired Cloudberry, vitamin C oils, raspberry seed. Plum kernel

Final Thoughts

So — do face oils really work? The science says yes.

They may not replace your water-based serums or creams, but they offer unique benefits that nothing else quite replicates: occlusive moisture retention, barrier repair, antioxidant delivery, and glow-enhancing nourishment.

When chosen wisely and layered correctly, face oils can be a transformative part of your skincare ritual — whether you’re soothing inflammation, fading dark spots, or simply protecting your skin from the world.
