Why Dilution Is Important?

Essential oils are 50–100 times more potent than the botanicals they come from. Using them undiluted can lead to:

• Skin irritation
• Sensitivity and inflammation
• Chemical burns
• Phototoxic reactions
• Headaches or breathing discomfort
• Allergic responses

Carrier oils like jojoba, almond, coconut, castor, and argan oil help dilute essential oils to safe levels while also adding nourishment.
