Fish

• Fish oil is one of the best natural substances you can use to fight acne. It offers a significant amount of vitamin A and zinc, which help heal skin and prevent scarring. You'll also get a healthy serving of Omega-3 fatty acids, which carry powerful anti-bacterial and anti-inflammatory effects. Mackerel, lake trout, herring, sardines, albacore tuna and salmon are all prime sources of Omega-3's.
  
  

Fruits and vegetables

• Vitamins are some of the best nutrients your body can digest. Beans and peanuts will give you a healthy dose of vitamins B5 and B6, and wheat foods are prime for folic acid. Eat plenty of whole-wheat bread, lentils, black-eyed peas, pinto beans, sunflower seeds, asparagus and spinach. Peppers, sweet potatoes, broccoli, dandelion greens, beet greens, mangoes and papayas will give you more than enough vitamin E. And parsley, cauliflower, strawberries, grapefruit, kiwi, oranges, cantaloupe, tomato, watermelon, cranberries, chili peppers and onions make it easy for you to take in a healthy level of vitamin C every day.
  
  

Honey facial

• You can also use some foods as topical creams that serve as antiseptics and antibacterials. One popular remedy is a honey facial. This is really simple; all you will need is some uncooked honey. Use a spoon to rub honey onto the irritated area of your skin and pat it down until it is sticky. After you leave it there for about five minutes, use a washcloth and water to remove it. The enzymes in honey help rejuvenate the skin and act as a antimicrobial.
  
  

Lemon juice wash

• The glycolic acids found in lemons help rid the skin of acne. Start out by washing your face with water and a washcloth. Squeeze lemon juice into a bowl, then dip a cotton ball in the juice and apply it to your face. After you let it dry for about 10 minutes, wash it off with cool water. The lemon juice may give you a burning feeling, but don't worry--that is supposed to happen. If your skin is really sensitive, you can dilute the juice with water.
  
  

Foods to avoid

• Dairy products, like milk, may be problematic for acne victims. Milk contains hormones that can aggravate acne by increasing sebum production and stimulating the growth of skin cells. It can also result in high insulin production, which causes acne, as well as inflammation. There are many calcium-rich foods that can be used as milk replacements.
  
  It's never good to eat a lot of junk food and it's even worse when fighting acne. Skip the bag of chips, the fast food and the fried chicken and try a healthier snack instead. You should cut out hydrogenated oils and trans-fatty acids as well. Iodine-rich foods like liver, cheese, iodized salt, clams, crabs and other shellfish are also associated with acne. Sugars and artificial sweeteners will weaken your skin's glucose tolerance, so candy and sodas should be consumed minimally.
