Vinegar has many uses, depending on the type of vinegar. If you are having a problem with acne, then try following these steps by using Rice vinegar.
Find a clean bottle or a clean spray bottle and add 3/4 purified or spring water (or approximately 6 ounces) to the bottle.
Add 2 tablespoons (or approximately 1 ounce) of rice vinegar to the water in the bottle, along with 2-3 drops of tea tree oil.
Place cap on the bottle and shake mixture. If you are using a spray bottle, place near shower for quick use on body acne. If using on body acne, simply spray solution on dried areas immediately following a bath or shower. If facial use is needed, continue to Step 4.
For facial use, using a regular bottle, uncap bottle and dampen several cotton balls or cotton pads. Then apply sparingly to clean skin, avoiding the eye area. Once dry you can then finish with your normal skincare regimen.
