Lavender Essential Oil: Uses, Blends and Safety

Lavender is the oil most people own first: sweet, clean and calming, the smell of fresh sheets and summer gardens. Here is what true lavender oil is, whether it’s phototoxic, why fresh oil matters so much, and how to use it safely.

Ask ten people to name an essential oil and most will say lavender. It is the scent of clean laundry and the slow end of a long day. It has been part of washing and bathing for so long that its name is often traced to the Latin lavare, to wash.

Because it’s so familiar, it’s easy to treat lavender casually. It is one of the gentler oils, but it has one real weak spot, and it isn’t the sun. It’s air.

The short version

Lavender essential oil is steam-distilled from the flowering tops of true lavender. Our label names it Lavandula angustifolia, and ours is made only from early-season blossom tops.
Its scent comes mostly from linalool and linalyl acetate, the two molecules behind lavender’s sweet, soft floral smell.
It is not phototoxic: it won’t make your skin burn more easily in the sun.
Its weak spot is oxidation. Exposed to air, lavender oil slowly forms compounds that are much more likely to cause a skin allergy. Keep it capped and cool, and use it while it’s fresh.
Dilute it for skin, keep it away from the eyes and out of reach of children, and diffuse only briefly around pets. The ASPCA lists lavender as toxic to cats and dogs.

Is Lavender Oil Phototoxic?

No. Lavender oil isn’t phototoxic. Robert Tisserand, co-author of Essential Oil Safety, has written plainly that lavender oil doesn’t make skin sensitive to sunlight.

Phototoxic oils contain furocoumarins, compounds that react with sunlight on the skin and can cause redness, blistering or dark patches that last for months. They show up mainly in cold-pressed citrus oils such as bergamot, lime and bitter orange, which is why those carry real sun limits. Lavender doesn’t contain them. Peppermint, the other oil people often ask about, is in the same boat; see our peppermint guide.

The sun note on our product pages is a general caution we give for every oil. Lavender itself isn’t known to cause sun reactions.

What Lavender Essential Oil Is

True lavender is a small, woody shrub native to the hills of the western Mediterranean, from northeastern Spain to Italy. Its slender stems carry narrow green leaves and tight spikes of small purple flowers.

The oil is made by steam distillation: steam passes through the freshly cut flowers, carries the aromatic oil with it, and the oil separates from the water as it cools. Ours is made only from the blossom tops of Grade-A crops picked at the very start of the season, when the oils in new blooms are most concentrated. No late-season stalks or woody pulp go in, just fresh flowers distilled at their best.

True lavender, lavandin and spike lavender

Three different plants are sold as “lavender”. Lavandula angustifolia, the name on our bottle, is true lavender, sometimes called English lavender. Spike lavender, Lavandula latifolia, is sharper and more camphor-like. Lavandin, Lavandula × intermedia, is a hybrid of the two, and it carries more camphor and cineole than true lavender, which gives it a harsher, more medicinal edge. They aren’t interchangeable, so check the label for the botanical name.

Can You Use Lavender Oil Neat?

We don’t recommend it. Lavender has a reputation as the one oil you can put straight on your skin, and fresh lavender really is one of the gentlest oils. The catch is what happens as it ages. Linalool and linalyl acetate react with oxygen in the air and form hydroperoxides, which are strong skin allergens. A 2008 study by Swedish researchers found that lavender oil has no natural protection against this: the whole oil oxidized just the way the pure molecules did.

Allergy to fresh lavender is rare. But once your skin is sensitized, it can react every time you use the oil, so diluting is cheap insurance. For the body, about 1 to 2% is plenty: 6 to 12 drops in 30 ml (1 oz) of a carrier oil such as jojoba or sweet almond. Use half that on the face, keep it away from the eyes, and try a small patch on your inner arm first.

How to keep it fresh

Keep the cap tight and the bottle somewhere cool and dark, and use an opened bottle within about a year. If your lavender starts to smell sharp, thin or less sweet than it did, that’s oxidation, and it’s time for a fresh bottle.

What It Smells Like, and What It Blends With

Lavender is a fresh, sweet floral middle note with a green, herbal edge and a soft, powdery woodiness underneath. It is the peacemaker of the oil shelf: it softens sharp oils and rounds out citrus.

A few diffuser blends to try, in drops for a standard water diffuser:

Fresh linen: 3 drops lavender, 2 drops Lemon
Fuller floral: 3 drops lavender, 2 drops Geranium Rose (more in our geranium rose guide)
Quiet evening: 3 drops lavender, 2 drops Frankincense
Soft citrus: 3 drops lavender, 2 drops Bergamot

How to Use Lavender Essential Oil

In a diffuser

Start with 3 to 5 drops in the water reservoir as the evening begins. It’s the classic wind-down scent. Diffuse for 30 to 60 minutes at a time rather than all night, in a room with some airflow.

In a linen mist

For sheets, pillowcases and towels, mix in a 100 ml (about 3.4 oz) glass spray bottle:

About 90 ml distilled water
About 10 ml witch hazel or high-proof vodka (it helps the oil disperse)
15 to 20 drops lavender, alone or with a few drops of lemon

Shake well before every spray, since oil and water separate. Mist from about a foot away and let the fabric dry before you use it. Test on a hidden spot first, especially on silk or anything delicate.

In drawers and closets

Put 3 or 4 drops on a cotton ball in a small dish and tuck it into a drawer or onto a closet shelf. Keep the oil off the fabric itself, since it can leave marks.

In a body or bath oil

For a body oil, stir 6 drops into 30 ml (1 oz) of jojoba or sweet almond oil, about 1%. For the bath, essential oils don’t mix with water, so stir 4 to 6 drops into a tablespoon (15 ml) of carrier oil first, then add it to the water. Mind your footing: oil makes the tub slippery.

What about the health claims you see online?

Search “lavender oil benefits” and you will find claims about sleep, stress, burns, headaches and more. Much of that research uses specific preparations, some of them taken by mouth, or small trials in clinical settings, not a diffuser at home. In the U.S., an oil sold to treat a health problem is regulated as a drug; ours is sold for its scent, and we don’t make health claims for it. If you are managing a health condition, talk with your doctor.

Using It Safely

A few simple habits keep lavender pleasant:

Dilute for skin, every time. See the dilution guide above.
Keep it fresh. Tight cap, cool and dark, and use it within about a year of opening.
Don’t swallow it. A bottle of essential oil is for the diffuser, linen mists and well-diluted skin use.
Eyes and sensitive areas: keep it away from the eyes, inner ears and broken skin.
Children: keep the bottle out of reach, and ask your pediatrician before using lavender on a child.
Pets: the ASPCA lists lavender as toxic to dogs, cats and horses, naming linalool and linalyl acetate, the same molecules that give the oil its scent. Keep diffusing brief, in a ventilated room your pet can leave, and never put oils on a pet’s skin or fur.
Pregnancy and medical care: check with your doctor before using it if you are pregnant, nursing, taking medication or under a doctor’s care.

How to Choose a Good Lavender Oil

A few things on the label tell you a lot:

The plant: Lavandula angustifolia, by name. “Lavender fragrance” isn’t an essential oil at all.
The part of the plant: flowering tops, steam-distilled.
One ingredient: lavender oil and nothing else, unless the label says it is pre-diluted.
Dark glass: light and air break oils down. A clear plastic bottle is a red flag.
Independent standards: our oils are Grade A, Certified ToxicFree® and Leaping Bunny certified. Here is what ToxicFree® certification means.

The Bottom Line

Lavender is the everyday oil: sweet, soft and calming, at home in the diffuser, the linen closet and the bath. It isn’t phototoxic. Its real enemy is air, so keep the bottle tightly capped and cool, use it while it’s fresh, and dilute it for skin. Do that, and your evenings and linens will smell the way lavender should.

FAQ: Lavender Essential Oil

Is lavender essential oil phototoxic?

No. Lavender doesn’t contain furocoumarins, the compounds that make some citrus oils phototoxic, and Robert Tisserand, co-author of Essential Oil Safety, has written that it doesn’t sensitize skin to sunlight.

Can I put lavender oil directly on my skin?

We don’t recommend it. Dilute to about 1 to 2% for the body (6 to 12 drops per 30 ml of carrier oil), half that for the face, and patch test first.

Does lavender oil go bad?

Yes, slowly. Its main molecules react with air and form compounds that are much more likely to cause a skin allergy. Keep it tightly capped, cool and dark, and use an opened bottle within about a year.

Is lavender oil the same as lavandin?

No. Lavandin is a hybrid of true lavender and spike lavender, with more camphor and a sharper, more medicinal smell. Our oil is true lavender, Lavandula angustifolia.

Is lavender oil safe around cats and dogs?

Be careful. The ASPCA lists lavender as toxic to cats and dogs. Diffuse only briefly in a ventilated room your pet can leave, keep the bottle out of reach, and never apply oils to a pet.

Can I use lavender oil around children?

Keep the bottle out of reach, diffuse briefly in a ventilated room, and ask your pediatrician before using lavender on a child’s skin.
