Essential Oils: How to Choose a Scent and Understand the Differences Between Oils

Lemon, rosemary, lavender, pine… Every essential oil has a slightly different effect and we are often naturally attracted to the scent we need most at a given moment.

When we are restless, lavender may be pleasant. In moments of fatigue, many reach for rosemary or mint. When we want some lightness and freshness, citrus scents like orange, grapefruit, or lemon are appealing.

Choosing an oil does not have to be complicated or technical. If you are starting out, simply use your nose. Scent is a very personal matter and intuitive choice is often the best first step.

What Are Essential Oils and How Do They Work

Essential oils, sometimes also called plant essences, are concentrated aromatic substances extracted from various parts of plants – flowers, leaves, bark, wood, needles, or citrus peels.

Each plant has a different composition, intensity, and character of scent. Some oils are fresh and light, others earthy, resinous, or floral.

This is why essential oils are used not only in aroma lamps and diffusers, but also:

• in homemade cosmetics,
• in perfume making,
• in massage blends,
• in bath oils,
• in candles,
• or simply for scenting textiles and spaces.

Differences Between Types of Oils

Not all essential oils behave the same. They differ in intensity, evaporation speed, and lasting power of scent.

Citrus Oils

Citrus oils are usually fresh, light, and evaporate quickly. This group includes:

• lemon,
• orange,
• grapefruit,
• mandarin,
• citronella.

They are often used for freshening spaces or in morning blends. In perfumery, they form the so-called top notes—the first scent you notice.

However, keep in mind that citrus scents usually fade the fastest.

Herb Oils

Herbal essential oils include:

• rosemary,
• mint,
• lemon balm,
• sage,
• thyme.

They tend to have a stronger character and are often used in hair or skin care. For example, rosemary is used in cosmetics for scalp care, mint is favored for its cooling effect, and geranium may be suitable for blends for oily skin.

Herbal scents are fresher than woody oils but more stable than citrus.

Floral Oils

Lavender, rose, ylang ylang, or jasmine are highly aromatic floral oils.

Lavender is popular mainly for its gentle and calming scent. Ylang ylang is intense, sweeter, and often used in perfume blends.

Floral oils are usually stronger and often form the middle of the scent.

Woody and Resinous Oils

Cedarwood, pine, patchouli, or sandalwood are types of oils that last very long.

They have deeper, more earthy notes and act as the base of the perfume. They help anchor and prolong the longevity of scents.

If your homemade perfume blends tend to fade quickly, adding a little woody oil often helps.

Even Essential Oils Don't Last Forever

Every essential oil evaporates at a different rate. Citrus scents are generally very volatile, while patchouli, cedarwood, or ylang ylang last much longer in a blend.

This is why perfumery works with:

• top notes,
• middle notes,
• base notes.

A well-mixed scent will gradually change and develop.

Scent Needs Time

If you've ever made your own perfume, you may have noticed the blend smells different immediately after mixing and then after a few weeks.

This is normal. The ingredients need time to blend and mature. Some sharp notes will soften, others will become more pronounced.

This is why it is recommended to let the perfume sit for at least a few weeks in a dark, cooler place after making it.

Using Essential Oils in Cosmetics

Essential oils are used as both active and aromatic ingredients in homemade cosmetics.

You can find them in:

• creams,
• massage oils,
• shampoos,
• balms,
• soaps,
• bath blends,
• or perfume oils.

As they are concentrated substances, it is important to use small amounts and follow dosage recommendations.

If you are just getting started, use simple recipes and lower concentrations. Even a small amount of essential oil is usually effective.

Before applying to skin, it is a good idea to test for tolerance and always dilute the oil in a carrier oil or suitable base.

Tip for Making a Fresh Perfume

For a simple fresh perfume you will need:

• 10 ml perfume base,
• 10 drops of citronella,
• 4 drops of lemon balm,
• 3 drops of rosewood.

Pour the base into a glass vial and gradually add the essential oils. Close the bottle and mix the blend gently.

Let the finished perfume rest for at least a month for the scents to blend well.

If you want to try making your own, start with one small bottle and a simple scent combination. Mixing your own is the best way to discover which oils truly suit you. Ingredients, vials, and more recipes can be found at Ekokoza—and if you need help choosing, let us know, we will happily advise.
