When you’re not using it, store it in a cool, dark place. Before putting neem oil on your face, do a patch test on your arm.

Because of the potency of neem oil, it’s a good idea to mix it with equal parts of a carrier oil — like jojoba, grapeseed, or coconut oil — when using it for larger areas of the face or body, or on sensitive skin. The carrier oil can also subdue the odor of neem oil, or you can add a few drops of other oils like lavender to improve the smell. Once the oils are blended, use the combination as you would a moisturizer on the face and body.

If you find the oil combination to be too oily, you can mix a few drops of neem oil with aloe vera gel, which also will be soothing to irritated skin.

Neem oil can also be added to a warm bath to treat larger areas of the body.

Neem oil is safe but extremely potent. It may cause an adverse reaction in someone with sensitive skin or a skin disorder like eczema. If it’s your first time using neem oil, start by trying a small, diluted amount of it on a small area of your skin, away from your face. If redness or itching develop, you may wish to further dilute the oil or avoid using it completely.

Hives, severe rash, or difficulty breathing could be a sign of allergic reaction. Discontinue use of neem oil immediately and consult a doctor if your conditions persist.
