Apple cider vinegar (ACV) has been one of my favorite skin ingredients for some time. Consumers may tire of the same old, same old when it comes to what they use for their skin, but the benefits of ACV are so numerous and varied that your skin’s capacity for absorption of these advantages will never cease.
Fermentation is used to make the cider into vinegar. During this process, bacteria and yeast break down the sugars in the cider. First the sugars are turned into alcohol, and when the alcohol ferments further, you get vinegar. The word vinegar comes from the French, meaning, “sour wine.” The main ingredient of apple cider vinegar is acetic acid, however it also contains other acids (lactic, citric and malic), vitamins, mineral salts, and amino acids.
