Cucumbers are a popular ingredient in facial treatments for good reason. This vegetable is not only super hydrating, cucumber also contains vitamin A, vitamin C, and magnesium – all of which are great for your skin. To use this treatment for healing acne scars just pick up an organic cucumber from your local market, cut off a few thin slices, and lay them over your scarred skin. After about thirty minutes, discard the cucumber slices and rinse your face with cool water. Repeat daily as desired.
