The high acidity of apple-cider vinegar makes skin inhospitable to blemish-causing bacteria. But watch out! Apple-cider vinegar stinks!
Place a handful of parsley (a skin-clarifying herb) into a French press and cover it with 1/2 cup of boiling water. Steep for 10 minutes, then plunge and let the liquid cool. Transfer to a spray bottle along with a splash of vinegar and four drops of tea tree oil (an antiseptic), shake well, and spritz on a freshly cleansed face. Store the spray bottle in the fridge.
