What Are Essential Oils?
Essential oils are natural, concentrated extracts derived from plants, flowers, roots, or resins. They are obtained through methods like steam distillation or cold pressing and are valued for their therapeutic benefits.
-
100% natural with no synthetic additives
-
Used in aromatherapy for relaxation, stress relief, focus, and mood support
-
Examples: lavender, eucalyptus, tea tree, frankincense

What Are Fragrance Oils?
Fragrance oils are typically synthetic blends, sometimes mixed with natural extracts, created to mimic specific scents. They are often used in candles, perfumes, soaps, and air fresheners.
-
Made in a lab—not purely natural
-
Typically stronger and longer-lasting scents
-
Wide variety of aromas not available in nature (e.g., vanilla cupcake, ocean breeze)

Which Diffuser Is Best for Essential Oils?
When it comes to diffusing essential oils, not all diffusers are created equal.
-
Ultrasonic diffusers use water and vibrations to disperse oils. While affordable, the water can dilute essential oils and alter their purity.
-
Nebulizing diffusers (waterless diffusers) use only air pressure to atomize pure essential oils into fine particles. This preserves the integrity, potency, and therapeutic value of the oils.
