How to Use Face Oil in Your Routine
Face oil is simple in theory — a few drops, pressed into skin. But the details of when, how much, and in what order make a bigger difference than most people expect. Get them right and an oil finishes a routine with a healthy sheen and real staying power. Get them wrong and it just sits there feeling greasy without doing much.
Step order, morning and night: serum, moisturizer & sunscreen
Apply oil last, after cleanser, toner or essence, any water-based serum, and moisturizer. Oil's larger molecules can't penetrate past a layer of cream. Putting it on earlier just blocks everything applied afterward from absorbing properly. At night, oil is the final step, full stop. In the morning, if sunscreen is part of the routine, apply oil before SPF. Give it a minute or two to settle so it doesn't thin out the sunscreen film or affect how evenly it sits.
How many drops: squalane, jojoba oil & rosehip oil
Two to four drops is enough for the whole face for most oils. Start with less than you think you need. Warm the oil between your palms first rather than dotting it directly onto skin — this spreads it more evenly and helps it absorb faster. Press it into skin rather than rubbing, especially around the eyes and any drier areas like the cheeks, where a slightly heavier hand is fine. Lighter oils like The Ordinary's squalane and The Inkey List's jojoba oil spread further per drop than a richer oil like rosehip oil.
Mixing oil into moisturizer vs. layering it on top
There are two workable methods. Layering — moisturizer first, then oil pressed on top once the moisturizer has mostly absorbed — gives the most sealing benefit. It's the better choice for genuinely dry skin. Mixing a couple of drops of oil directly into moisturizer in your palm before applying is faster and uses less product overall. It's also a good way to introduce oil gradually if you're new to it or unsure how your skin will react. Neither method is wrong; layering gives slightly more control, mixing is more convenient.
Using oil with retinol or vitamin C serum
Oil generally goes after other actives, not before or mixed in with them, since most actives need direct contact with skin to work rather than being diluted into an oil base. On retinol nights, apply retinol first, wait a few minutes, then follow with a moisturizer and oil to help offset the dryness retinol can cause. Oil is actually one of the more useful tools for making a retinol routine more tolerable. With a vitamin C serum in the morning, let it absorb fully before layering moisturizer and then oil on top. Oil applied too early can interfere with how vitamin C settles into skin.
Using oil for gua sha or facial massage: oily skin vs. dry skin
For gua sha specifically, apply more oil than you would for daily moisturizing — enough that skin looks visibly glossy, not just hydrated. Work in small sections rather than trying to oil the whole face at once, since oil applied too early on one area can absorb before you get to it with the tool. If the stone or roller starts to catch or drag partway through, that's the signal to add more oil rather than push through the friction. Oily skin can usually get away with a lighter hand than dry skin needs. A lightweight oil like squalane or jojoba oil is easiest to control for this, since it doesn't leave as heavy a residue afterward as a richer oil would.
Troubleshooting pilling, greasiness & patch testing
- Pilling usually means too many product layers, or applying oil before a previous layer has finished absorbing. Give each step 30–60 seconds before adding the next.
- Persistent greasiness hours after application usually means too much product, not the wrong oil. Cut back to half the amount and reassess.
- Oil sitting on top without absorbing can mean skin underneath is under-hydrated. Check that a water-based step is actually happening before the oil, not just a rinse-off cleanser.
- New reactions — redness, itching, or breakouts after switching oils — mean it's time for a patch test on a new oil before using it on your whole face again.
Storage, shelf life & how oils oxidize
Keep oils away from direct sunlight and heat, ideally in a cool, dark cupboard rather than a steamy bathroom shelf. Rosehip oil and other oils high in polyunsaturated fatty acids oxidize fastest. They're usually best used within three to six months of opening. Squalane and jojoba oil are more stable and last longer. A change in smell — anything sharp, sour, or crayon-like — is a sign an oil has oxidized and should be replaced rather than used.
