Can I use this oil directly on my skin for a quick scent?

No, this oil should not be used undiluted on the skin. Essential oils are highly concentrated plant extracts. Applying them 'neat' can lead to skin irritation, redness, or sensitization, especially for those with sensitive skin. For a safe skin application, such as in a massage blend, you must dilute it in a neutral carrier oil like fractionated coconut, jojoba, or sweet almond oil. A common, safe dilution for a general body massage is about 1-2%: this translates to roughly 1 to 2 drops of lemongrass essential oil per teaspoon (5 ml) of carrier oil. For facial applications or more sensitive skin, a 0.5% dilution (1 drop per 10 ml of carrier) is recommended. Perform a patch test on a small area of your inner arm before full application.
