How is hemp oil used?
There are several methods you can use to get the skin benefits from hemp oil.
Topical use of hemp oil
The first method is to apply the hemp oil directly to your skin. This can work if you have immediate irritation or dry patches of skin that you want to soothe quickly.
Before using the oil, try a patch test to make sure you won’t get an unwanted reaction:
Wash and dry a small area of your upper arm (such as the crook of your elbow).
Apply a small amount of the pure hemp oil. (If using the hemp and essential oil mixture described below, test in a separate spot from the pure oil and at a different time.)
Cover the spot with a bandage and leave it in place for 24 hours, being careful not to get the bandage wet.
If any redness, burning, itching, or other irritation occurs, you can assume you’re sensitive to the oil and shouldn’t use it. If you have a reaction, remove the bandage immediately and wash the spot with soap and water.
If you don’t see or feel any reaction, then the oil is probably safe to use.
If you’re using the hemp oil to treat acne and want to apply it topically, apply the oil directly to clean skin and leave it on for one to two minutes before washing it away with warm water.
Hemp oil and essential oil mixture. You can also combine hemp oil and other anti-inflammatory and soothing ingredients with a recipe like the following, which can be applied directly to the skin:
1/4 cup hemp oil
2 teaspoons melted coconut oil (can be melted in the microwave; place desired amount in a microwaveable container and heat in 30 second intervals, stirring between each interval, until completely melted)
4 to 5 drops skin-boosting essential oil, like lavender or rosemary oil
Note: Essential oils, like lavender or rosemary oil, should only be used topically and in a diluted mixture. Do not take essential oils internally. Many are toxic.
Oral use of hemp oil
The second method is to ingest hemp oil, which can provide the same skin benefits and additional overall health benefits as using the oil topically. If you take hemp oil orally, there’s less risk of any skin irritation or break outs, although it may cause some temporary digestive upset.
Talk to your doctor before taking hemp oil orally.
If you do take it orally, you can have 1 to 2 teaspoons daily — either all at one time or divided into two doses.
If you don’t like the taste or consuming the hemp oil straight, you can also use it in different recipes. One option is to mix it into foods, like smoothies, salad dressings, or soup. Or you can use it for cooking.
