Natural perfume is not automatically better than perfume made with synthetic materials. Natural materials — essential oils, absolutes, resins — offer depth and variation; synthetic materials offer consistency, effects nature cannot provide, and alternatives to scarce or protected natural sources. Both can cause allergic reactions in sensitive people, both can be produced well or badly, and most fine perfumes combine them. What matters more than the origin of each material is how well the perfume is composed and whether it suits you.

What the words mean

  • Natural materials are taken from plants (and, historically, a few animals) by distillation, pressing or extraction. Each is a complex mixture of many molecules. See How Perfume Ingredients Are Extracted.
  • Synthetic materials are made by chemical processes. Some are identical to molecules found in nature, such as vanillin; others have no natural counterpart.
  • "Natural" perfume usually means one made only or mostly from natural materials. There is no single legal definition in most markets, so the claim varies from brand to brand.

What natural materials offer

  • Complexity. A natural oil contains hundreds of molecules, giving richness that is hard to reproduce.
  • Variation. Each harvest is slightly different — a pleasure for some, a challenge for consistency.
  • Tradition and craft. Many natural materials carry long histories and support farming communities.

What synthetic materials offer

  • Consistency. The same molecule smells the same every time.
  • New effects. Clean musks, transparent woods, aquatic and aldehydic notes — much of what modern perfume smells like — would not exist without them. See How Synthetic Molecules Created Modern Perfume.
  • Protection of scarce sources. Synthetic musks replaced musk from protected deer; synthetic sandalwood and ambergris-like materials reduce pressure on rare natural sources.
  • Notes nature doesn’t provide. Many flowers, such as lily of the valley, and fruits give no usable extract. See Are Perfume Notes Real Ingredients?.

The question is not whether a material came from a field or a flask. It is whether it was used well.

Is natural safer?

Not as a rule. Many of the fragrance substances that must be named on labels in the EU because they can cause allergic reactions occur naturally in essential oils — linalool and limonene in citrus and lavender, for instance — and natural extracts can contain several of them at once. Safety depends on the specific material and how much is used, which is why industry standards and regulations assess materials individually rather than by origin. See How to Read the Ingredient List on a Perfume.

Is natural better for the environment?

It depends. Natural materials can support farmers and renewable crops; they can also require large amounts of land, water and harvesting, and over-harvesting has endangered some species. Synthetic production has its own footprint. Neither origin is automatically the more sustainable; the specific material and its supply chain matter.

Does natural perfume last as long?

Often not. Many of the long-lasting base materials in modern perfume are synthetic, and all-natural perfumes tend to be softer and shorter-lived, with a more rounded, less radiant character. Many people love them for exactly that. See How to Make Perfume Last Longer.

What to ask instead

  • Do I like how it smells, through the whole day?
  • Does it suit my skin, without irritation?
  • Is the brand open about what it means by "natural", "clean" or "sustainable"?

Common questions

Are synthetic fragrances bad for you?

Synthetic fragrance materials used in perfume are subject to the same safety standards and regulations as natural ones. Some people are sensitive to particular materials of either origin.

Is "fragrance" on a label always synthetic?

No. "Parfum" or "fragrance" covers the whole perfume concentrate, natural and synthetic materials alike.

Why are natural perfumes more expensive?

Many natural materials are costly to grow and extract, and vary in supply.
