Labels often list “fragrance” or “essential oils,” yet they are not the same. Fragrance is usually a mix of undisclosed chemicals. Essential oils are concentrated plant extracts that must be diluted and used with care. Knowing the difference helps you choose what truly supports your skin and nervous system.

What Are Essential Oils?

Essential oils are distilled or cold-pressed plant extracts. Many show antimicrobial, anti-inflammatory, and antioxidant activity in lab and clinical contexts. Use them diluted, patch test first, and avoid sensitive areas. Even natural ingredients can irritate skin.

Examples from research

‍Lavender promotes relaxation and sleep, peppermint aids with headaches and digestion, and tea tree oil is valued for its antimicrobial effects in skincare.

Research from the NCCIH suggests essential oils can reduce stress, support emotional well-being, and offer mild pain relief when used appropriately.

What is “fragrance” or “parfum”?

“Fragrance” or “parfum” on a label can legally stand in for a proprietary blend. U.S. rules allow companies to keep fragrance formulas as trade secrets, so the specific chemicals are not listed. This limits transparency for consumers who need to avoid certain allergens.

Why people choose to avoid synthetic fragrance

  • Possible skin irritation and allergy risk from certain fragrance components.
  • Phthalates may be used in some fragranced products to help scents last longer, and are associated with endocrine-disrupting properties.

Bottom line: which is “better”?

Neither category is risk-free. Essential oils can offer skin-supportive benefits when used properly, but they still require dilution and care.

Synthetic fragrance offers consistent scent but lacks full ingredient disclosure and can be irritating for sensitive skin. Many people with reactive skin choose fragrance-free or transparent, essential-oil scented products, then patch test to confirm tolerance.

How to choose safer, skin-friendly products

  • Scan the label. Prefer “fragrance-free” or fully disclosed essential oil blends. Be cautious with vague “fragrance” or “parfum.”
  • Dilution matters. For leave-on face products, keep essential oils very low and avoid the eye area. Patch test.
  • Quality and freshness. Choose reputable brands, store oils away from heat and light, and replace old products to reduce oxidation-related irritation.
  • Sensitive seasons. During pregnancy or postpartum, simplify. Many topical tea tree products are considered usable for most people, yet caution and patch testing are still advised. When unsure, choose fragrance-free.
  • Your rhythm, not perfection. If you react to scent, go fragrance-free. If you enjoy aromatics, choose gentle, clearly labeled essential oil formulations and listen to your skin.
    Beyond ingredients, sustainable packaging and ethical practices matter. Brands like All Tree Roots prioritize transparency and avoid synthetic fragrances, promoting a holistic approach to skincare. By choosing clean, responsibly sourced products, you reduce chemical exposure and support both your health and the environment.

    • Key Takeaways

    • Essential oils: plant-derived, require dilution, can offer antimicrobial and anti-inflammatory support for some skin goals. Not risk-free.
    • Fragrance/parfum: umbrella term for undisclosed mixtures allowed as trade secrets. Can be harder to avoid specific allergens.
    • Phthalates: sometimes associated with fragranced products and have endocrine-disrupting properties.
    • Safer choices: choose fragrance-free or fully disclosed essential-oil scented products, patch test, and favor short, transparent ingredient lists.
