Once you have grown past your acne phase, the scars may last quite a bit longer. Fortunately, there are a number of natural remedies for acne scars that can stimulate the healing process and reduce their appearance on your face. Cucumber slices are commonly used in facials and other cosmetic procedures, and with good reason. Cucumber is packed with minerals and vitamins that can improve the appearance of the skin. If you drink cucumber juice, it can act as a skin toner, smoothing over the areas where scars have formed and reducing their visibility.
