This product is 100% pure orange essential oil and must be diluted before skin contact. A common and safe dilution ratio for cosmetic use is between 1% and 2%. This means adding 1 to 2 drops of essential oil for every teaspoon (approximately 5 ml) of a neutral carrier oil like jojoba, sweet almond, or fractionated coconut oil. For facial applications or if you have sensitive skin, starting with a 0.5% dilution (1 drop per 10 ml of carrier oil) is advisable. Always mix the blend thoroughly in a clean glass or ceramic container before use. It is crucial to perform a patch test on a small area of your inner forearm 24 hours before wider application to check for any skin sensitivity or irritation. Remember to avoid the eye area entirely.
