Face Oil vs Moisturiser: Do You Need Both? A Complete Guide

In the world of skincare, few debates are as common as face oil vs moisturiser. Some swear by a rich cream, while others claim oils are all you need. But what does your skin actually require? The answer isn't one or the other—it's understanding how each works and when to use them together.

This guide breaks down the science of face oils and moisturisers, compares their benefits, and helps you decide whether to use both. We'll also share tips on layering them effectively for your unique skin type, so you can achieve that healthy, balanced glow.

What Is a Face Oil?

Face oils are concentrated lipid-based formulations designed to mimic the skin's natural sebum. They are typically made from plant-derived oils rich in fatty acids, antioxidants, and vitamins. Their primary role is to strengthen the skin barrier, lock in moisture, and deliver nourishing actives deep into the skin.

Because oils are occlusive by nature, they help prevent transepidermal water loss (TEWL), keeping your skin hydrated for longer. They are especially beneficial for dry or mature skin types, but even oily skin can benefit from the right oil—it signals the skin to produce less sebum. Face oils are not a replacement for hydration; they are a sealant.

• Face oils are occlusive: they create a barrier that prevents moisture loss.
• They are rich in essential fatty acids like linoleic acid and oleic acid.
• Oils can be used alone or layered over a moisturiser for extra nourishment.

What Is a Moisturiser?

A moisturiser is a water-based or emulsion-based product that contains humectants (like glycerin or hyaluronic acid), emollients, and sometimes occlusives. Its main job is to hydrate the skin by attracting water into the upper layers and then sealing it in. Moisturisers also deliver active ingredients like peptides, ceramides, and antioxidants.

Moisturisers come in various textures—gels, lotions, creams, and balms—to suit different skin types. They are essential for maintaining a healthy skin barrier and preventing dryness, flakiness, and sensitivity. Unlike oils, moisturisers provide water content, which is crucial for plump, supple skin.

• Moisturisers contain humectants that draw water into the skin.
• They provide both hydration (water) and nourishment (lipids).
• Available in lightweight gels to rich creams for every skin type.

Key Differences Between Face Oil and Moisturiser

The fundamental difference lies in their composition and function. Face oils are lipid-based (no water), while moisturisers are water-based with an emulsion of oils and water. Oils work by sealing moisture in, whereas moisturisers actively add water to the skin.

Another difference is how they interact with your skin. Oils are more occlusive and can feel heavier, making them ideal for dry or compromised skin barriers. Moisturisers, especially lightweight gels, are better for oily or combination skin as they hydrate without clogging pores. However, many moisturisers contain oils too, blurring the line.

In a routine, you can use both: apply a moisturiser to hydrate, then a few drops of face oil to lock it in. This layering technique is often recommended for maximum benefits, especially in colder months or for those with very dry skin.

• Face oils are occlusive; moisturisers are hydrating.
• Oils are lipid-based; moisturisers contain water and humectants.
• Layering both can provide optimal hydration and barrier support.

Face Oil Benefits: Why You Might Need One

Face oils offer a range of benefits that moisturisers alone may not provide. They are packed with antioxidants and essential fatty acids that help repair the skin barrier, reduce inflammation, and improve elasticity. Oils like rosehip, jojoba, and squalane are non-comedogenic and suitable for sensitive skin.

For those with dry or flaky skin, a face oil can be a game-changer. It provides a protective layer that prevents moisture loss and soothes irritation. Additionally, oils can boost the efficacy of your moisturiser by sealing in its active ingredients. If you're looking for a natural glow, a facial oil can add a luminous finish that creams often lack.

• Face oils are rich in antioxidants and fatty acids.
• They help repair the skin barrier and reduce redness.
• A few drops can add a healthy, dewy glow.

Moisturiser Benefits: Why You Can't Skip It

Moisturisers are the cornerstone of any skincare routine because they provide essential hydration. Without water, your skin becomes tight, dull, and prone to fine lines. Humectants in moisturisers draw moisture from the air and deeper layers of the skin, keeping it plump and bouncy.

Moisturisers also deliver a cocktail of beneficial ingredients like ceramides, niacinamide, and peptides that support the skin barrier. They are versatile and can be tailored to your skin type—from oil-free gels for oily skin to rich creams for dry skin. Even if you use a face oil, a moisturiser ensures your skin gets the water it needs to function optimally.

• Moisturisers provide essential water content to the skin.
• They contain humectants that attract and hold moisture.
• They deliver active ingredients that oils cannot carry.

Do You Need Both? How to Layer Them

The short answer is: yes, you can benefit from both. The key is to apply them in the right order—moisturiser first, then face oil. This allows the humectants in the moisturiser to draw water into the skin, while the oil seals it in and prevents evaporation. This layering technique is especially effective for dry or dehydrated skin.

For oily or combination skin, you might prefer a lightweight moisturiser and a few drops of a non-comedogenic oil like squalane. Alternatively, you can mix a drop of oil into your moisturiser to simplify your routine. Listen to your skin: if it feels tight or looks dull, add an oil; if it feels greasy, skip the oil and stick to a gel moisturiser.

• Apply moisturiser to damp skin, then follow with face oil.
• Mix a drop of oil into your moisturiser for a quick fix.
• Adjust based on season and your skin's needs.

Choosing the Right Products for Your Skin Type

When it comes to selecting a moisturiser, look for one that matches your skin type. For dry skin, a rich cream with ceramides and fatty acids is ideal. For oily skin, a lightweight gel or lotion with hyaluronic acid works best. If you have sensitive skin, opt for fragrance-free formulas with soothing ingredients like centella asiatica.

For face oils, choose one that suits your concerns. For example, a vitamin C oil can brighten dull skin, while a rosehip oil can help with scarring. At Pai Skincare, we offer a range of products designed to work together. Our C-2 Believe Moisturiser is a great option for normal to dry skin, providing intense hydration without heaviness. For an extra boost, our Back to Life Serum delivers a potent dose of nutrients, while our Retinoid 0.3% Skin Renewal Booster can help with texture and fine lines.

If you're new to oils, start with a lightweight formula like our Twin Flyer Cleansing Cloths? No, that's a cleanser. Instead, consider our Stabilised Vitamin C 20% Brightening Booster for a glow, or our Salicylic Acid 2% Clarifying Booster for blemish-prone skin. These are not oils but can be used alongside your moisturiser for targeted benefits.

• For dry skin, choose a rich moisturiser and a nourishing oil.
• For oily skin, pick a gel moisturiser and a lightweight oil like squalane.
• Sensitive skin should look for fragrance-free, gentle formulas.

The Verdict: Face Oil vs Moisturiser

So, do you need both? The answer is: it depends on your skin's needs. If your skin is well-hydrated and your moisturiser is enough, you may not need a separate oil. But if you struggle with dryness, flakiness, or a compromised barrier, adding a face oil can make a significant difference.

The best approach is to experiment and observe how your skin responds. Start with a moisturiser, and if you feel you need more nourishment, introduce a face oil. Remember, skincare is personal—what works for others may not work for you. Listen to your skin and adjust accordingly.

• Use both if your skin feels tight or dry.
• Skip the oil if your skin is oily and your moisturiser suffices.
• Layering is a great way to customize your routine.

Ultimately, face oils and moisturisers serve different purposes, and using both can elevate your skincare game. Start with a hydrating moisturiser like our C-2 Believe Moisturiser, then lock it in with a nourishing face oil. Explore our range to find the perfect combination for your skin.
