Cornstarch & Vinegar for Blackheads
Get rid of blackheads! Pour ¼ to ½ cup of cornstarch into a bowl and add vinegar slowly while stirring. Add the vinegar until the mixture forms a thick paste. Apply the mixture to the blackhead affected areas on your face and leave on for 20 minutes. The mixture will dry to a hard plaster-like substance in the meantime. Rinse it off with warm water, and follow this with a cold water rinse to close the pores.
