How to Treat Oily Skin
To treat oily skin, wash your face twice a day with soap designed for oily skin. Use hot water when you wash your face to break down oils and open your pores. In addition to washing your face, you can exfoliate your skin by mixing coffee grounds and honey, baking soda and water, or sea salt and water, and scrubbing your face with the mixture for 1 to 2 minutes. After washing and exfoliating your face, apply a toner, like witch hazel, tea tree oil, apple cider vinegar, or green tea to help close your pores and remove any excess oils.
Set up a consistent wash schedule. Oily skin becomes more oily often for two reasons: you wash your skin too often, or not enough. Washing your face too often dries out your skin, causing your body to try to compensate by creating more oil. Washing your face infrequently causes old oil to build up. Find a happy medium by washing your face twice daily; when you wake up and before you go to bed is the best time. Use a special facial soap. Some soaps dry out your skin too much, causing your face to create more oil while others contain ingredients that clog pores and create more oil as well. Find a facial soap - bar or liquid, it doesn't matter - that is made especially for oily skin. For extremely oily skin, a detergent facial soap may be considered, but this may be too harsh and dry out your skin too much. Use the right water temperature. When you're washing your face, use hot water; this will break down the oil more effectively than cold or warm water is able to. Hot water also opens your pores, making it easier to clear out the excess oil. When you finish washing your face, splash it with ice cold water. This will close up the pores and tighten the skin, keeping it clear of oil and grime for longer. One option is to try out witch hazel. This works as a great all-natural facial toner. It will close up your pores and dry up excess oil when applied to your face after washing. Pour a bit of witch hazel onto a cotton ball, and dab it onto your face after washing. There is also a rose water witch hazel combination toner on the market that is great for oily skin. Make a tea tree toner. All natural tea tree oil is great for oily skin and acne/blemish-prone skin. Mix equal parts of tea tree oil with water, and mist it onto your face or apply it with a cotton ball. You can also add a few drops of tea tree oil to any of your other favorite toners. Use apple cider vinegar. Although it may sound frightening because of the scent, apple cider vinegar is a good option for oily skin. Apply it directly to your face after washing, or mix equal parts vinegar with water. There will be a scent when you apply it, but after a short while (when the vinegar has evaporated) the smell will disappear. Make a green tea toner. Full of antioxidants and skin-purifying nutrients, green tea is a great option for oily skin. Make your own green tea toner by brewing an extra-strong cup of pure green tea, and allow it to cool. It can be applied to your face twice daily after washing with a spray bottle or a cotton pad. Try sea buckthorn seed oil. Another natural oil, sea buckthorn has been used to treat skin ailments for many years. Combine a small vial of the oil with equal parts of water and dab it onto your face. You can also choose to add a few drops of the oil to your other favorite toners as an alternative to using it alone. Purchase a specialty toner. There are dozens of oil-prone skin toners available on the market, each with varying results. Try out a toner that is advertised for oily skin, and see how it works. Make sure it doesn't have any added fragrance as this can irritate your skin. Make a gentle oatmeal and aloe exfoliant. Scrub off dead skin, grime, and oil with an oatmeal scrub. Blend oatmeal in a food processor to break it up into smaller, grittier bits. Mix this with a bit of aloe vera to form a paste. Rub your face vigorously with the combination for 1-2 minutes, and then rinse off with warm water. Follow up with a toner. Try an almond meal scrub. Ground almonds are full of nutrients that are great for your skin, and make a great natural exfoliant. Mix a tablespoon of ground almond meal (make your own by blending a few almonds) with honey to form a paste. Rub it over your entire face for 1-2 minutes before rinsing off with warm water and dabbing your face with a toner. Make a sea salt scrub. Sea salt is used in many facial products for its skin-boosting benefits. Use a fine-grain sea salt, or blend some up to minimize the coarseness. Mix the sea salt with a bit of water to form a paste, and rub your face well with the mixture. Rinse it off with warm water. Sea salt can dry out some types of skin, which can in turn cause excess oil production.Limit your uses of sea salt on your skin, no more than once a week. Exfoliate your face with baking soda. Baking soda works double time as an all natural anti-inflammatory and antiseptic, as well as an ultra-fine exfoliant. Mix a tablespoon of baking soda with a bit of water to form a paste, and scrub your face down with it for 1-2 minutes. Rinse off the baking soda with a bit of cool water. Baking soda can act as both as acid and a base as an amphoteric. It's perfectly fine to use on your skin, though it's sometimes a little irritating on very sensitive skin. Do a patch test on a small part of your skin before try it on your face. Use coffee grounds as an exfoliant. If you're looking for a delicious-smelling facial scrub, then coffee grounds are the way to go. Mix the grounds with a bit of honey, and then scrub your face with the mixture for 1-2 minutes. Rinse the mixture off with warm water, and then coat your face with your favorite toner afterwards. Keep your hair away from your face. Your scalp creates the same oil for your hair as your face does for your skin; avoid adding more oil to your face by pulling your hair away from it. Similarly, some shampoos contain ingredients that can make your face more oily. Pin bangs away from your face, or pull your hair back in a ponytail. Blot your face with blotting papers. If you notice your face getting shiny during the day, use a special oil blotting paper or a single-ply tissue paper to absorb the excess oil. Don't rub your face, but rather press the paper to your skin gently to absorb the excess oil. Wash your pillowcases often. When dirt and oil build up on your pillowcase, the oil will transfer back to your skin while you sleep. Wash your pillow cases with a gentle detergent every 1-2 weeks to keep it clean; you should notice a dramatic difference in the oil production of your skin after a few months as a result. Switch to oil-free makeup, or no makeup at all. Makeups made with oil can, consequently, increase the amount of oil on your face. Either switch to a makeup that is oil-free, or don't wear makeup at all. The former is the best for your skin, but if you have acne or blemish problems making the complete switch may be difficult.
