Not necessarily. If your moisturizer keeps your skin comfortable until your next routine, you don't need a face oil. If your skin still feels tight or looks flaky in heated rooms, two or three drops of a simple, non-fragrant oil such as squalane or jojoba, pressed over moisturizer at night, can help it hold on to water. Oily and acne-prone skin can usually skip it.
What a face oil does — and doesn't do
Oils don't contain water, so they don't hydrate on their own. What they do is soften the skin's surface and slow water from evaporating. That's why an oil works best as the last step, over a hydrating toner and moisturizer, not instead of them. If you put oil first, water-based products can struggle to absorb through it.
| Step | Job |
|---|---|
| Toner, essence, serum | Add water and water-loving ingredients |
| Moisturizer | Hydrate, soften and seal |
| Face oil (optional) | An extra soft seal on very dry skin |
More on the jobs of each layer: humectants, emollients and occlusives.
Who benefits
- Very dry skin that still feels tight an hour after moisturizing.
- Flaky patches around the nose, mouth or brows in heated rooms.
- People who want a soft, dewy finish at night without switching to a heavier cream.
Who can skip it
- Oily or congestion-prone skin — a richer moisturizer at night is usually enough.
- Anyone whose skin is comfortable with their current cream.
- Anyone who reacts to plant oils or fragrance. Many oils are blended with essential oils or perfume.
Which oils are gentler?
| Usually gentle | Check carefully |
|---|---|
| Squalane (a stable, lightweight oil; see squalane for skin) | Blends listing essential oils, parfum or fragrance |
| Jojoba (technically a liquid wax, close to skin's own oils) | Heavy oils on acne-prone skin |
| Sunflower seed oil | Oils you haven't patch tested |
An essential oil isn't the same thing as a face oil. Lavender, citrus peel or eucalyptus oils are mainly there for scent and are a common source of irritation for sensitive skin.
How to use a face oil
- Apply your usual toner, serum and moisturizer.
- Warm 2–3 drops between your palms and press them over dry areas.
- Or mix one drop into your moisturizer if you prefer a single layer.
- Use it at night. In the morning, a thin layer can make sunscreen slide or pill.
By skin type
- Very dry: 2–3 drops over moisturizer every night in the coldest months.
- Dry patches only: one drop pressed onto the patches, not the whole face.
- Combination: on the cheeks only, a few nights a week.
- Oily or acne-prone: usually skip it; if you want to try one, start with squalane every other night.
- Sensitive: a single, simple oil with no essential oils, after a patch test.
An alternative: a moisturizer with oils built in
If you'd rather not add a step, pick a moisturizer that already includes lightweight oils. The Maple Energy Infusing Cream contains squalane in a syrupy, rich texture (no added fragrance listed). The Blue EGF Intensive Pro Cream pairs squalane and meadowfoam seed oil with ceramide NP and cholesterol (no added fragrance; contains guaiazulene). For more options, see Klairs moisturizers from lightest to richest.
Face oil or a richer moisturizer?
| Choose a face oil if… | Choose a richer moisturizer if… |
|---|---|
| You like your current moisturizer and only need a bit more seal at night | Your current moisturizer feels thin by midday |
| You want to adjust how rich your routine is day by day | You'd rather keep the routine to fewer steps |
| Your dry patches are small and specific | Your whole face feels tight |
Patch test an oil first
Plant oils are natural, but natural doesn't mean gentle for everyone. Apply a drop to your jawline for three or four nights before using it on your whole face. Watch for small bumps, itching or redness. If you're prone to clogged pores, try it every other night at first.
Signs you're overdoing it
- Your skin looks greasy but still feels tight underneath — you need more water-based hydration, not more oil.
- New small bumps or clogged pores appear.
- Makeup slides off within an hour.
Who it's for — and who should skip it
| Good fit if… | Skip or adjust if… |
|---|---|
| Very dry or flaky winter skin; you like a dewy night finish. | Oily or acne-prone skin, or you react to plant oils — stick with a richer moisturizer. |
FAQ
Does face oil hydrate skin?
Not on its own. Oils don't contain water. They help skin hold on to the water from your toner and moisturizer.
Should face oil go before or after moisturizer?
After, as the last step at night. Or mix a drop into your moisturizer.
Can oily skin use a face oil in winter?
It can, but it usually doesn't need one. A lighter moisturizer plus a richer layer only on dry patches is often enough.
Do face oils clog pores?
Some heavier oils can for some people. Lightweight options like squalane are less likely to, but patch test and watch for new bumps.
Is squalane a face oil?
Yes. Squalane is a light, stable oil that suits most skin types, including sensitive skin.
Can I mix face oil into my moisturizer?
Yes. One drop mixed into your moisturizer in your palm is an easy way to make it a little richer on cold nights without adding a step.
