Summarize:

Fill a one-quart pot with water and boil it for a minute. Add one to two drops of essential oils (or use 1/2 teaspoon of dried herb for every quart of water). Using essential oils can help your body quickly reabsorb blind pimples or draw them out so they heal faster. Some essential oils can even prevent pimples. Boil the water for another minute after adding the essential oil. Choose one of the following oils:  Spearmint or peppermint: these contain menthol which is an antiseptic and can improve your immune system. Since some people find mint irritating, start by using one drop for every quart of water. Calendula: this plant accelerates healing and has antimicrobial properties. Lavender: this herb is soothing, calming and can help with anxiety and depression. It also has antibacterial properties. Since essential oils come from plants, you should test for skin sensitivity to the plants before you steam your face. Place a single drop of the essential oil on your wrist and wait 10 to 15 minutes. If you have a sensitivity or allergy to the oil, you'll probably see a mild rash that may or may not be itchy. If you have no sensitivity, you can steam your face. If you do have a sensitivity, continue testing for a different oil to use. Remember that you can develop sensitivity to an herbal oil that you didn't used to react to. This is why it's important to always test an oil for sensitivity. Turn off the stove and move the pot away. Tie your hair back so it's out of your way and cover the back of your head with a large, clean cotton towel. Bend over the steaming pot so that the towel falls around the sides of your face, trapping the steam.  Close your eyes, breathe normally and relax for 10 minutes. Rinse your skin with lukewarm water and pat it dry with a clean towel.  Be sure to keep your face at least 12 to 15 inches (30.5 to 38.1 cm) away from the water so you don't burn yourself. To repeat steam facials throughout the day, simply reheat the water till it starts to steam. Steaming will open up your pores to clean out deep debris and facial oil. This can draw out the blind pimple. Seal in the moisture from the steam facial by applying a moisturizer. Select a non-comedogenic moisturizer. This won't clog your pores or contribute to acne. Moisturizing also helps prevent damage to your skin while keeping it soft and flexible. If your skin is sensitive to products you use, look for a moisturizer that doesn't contain fragrance or perfume.
Heat and mix your water. Test the oil on your skin. Steam your face. Apply a moisturizer.
