Apple cider vinegar is one of the most commonly used home remedies because of its acid. The acid in the apple is embedded in the pores and provides deep cleansing. This remedy is perfect for oily skin because it reduces oiliness. Once you have cleansed your skin with apple cider vinegar, use a cotton pad with vinegar and dab it onto your skin. Avoid the lip and eye area. Afterwards, rinse with warm water.
