Acne is a condition mostly common in teenagers; however, people of all ages can suffer from acne, according to the Mayo Clinic. Acne forms in teenagers due to hormonal changes. Other key contributors to acne development include excess oil, bacteria and clogged pores. There is a selection of food you can supplement into your diet, rich in a variety of vitamin and minerals that help to prevent or treat acne and inflammation.

Watermelon

Watermelon is an excellent source of vitamin C, according to the University of Maryland Medical Center. Vitamin C helps to keep your skin hydrated and assists in the production of collagen, a protein that is responsible for making skin and scar tissue. Vitamin C is an antioxidant vitamin -- protecting your body from free radicals, substances that can result in skin issues, causing your skin to become brittle and dry, resulting in acne or irritating the condition. Vitamin C also enhances your immune system, boosting its ability to eliminate bacteria, viruses and other dangerous substances that may harm your skin cells or tissues.

Crab

Crab is a good source of the mineral zinc. Zinc is beneficial for acne suffers because it can help to enhance the healing speed of inflamed acne. Zinc, like vitamin C, also has antioxidant properties, fighting off free radicals. According to the Vitamin & Nutrition Center, zinc helps to prevent acne formation by regulating the activity of oil glands on your skin. In addition, zinc also helps to keep your immune system healthy. According to the University of Maryland Medical Center, a lack of zinc in your body can cause skin problems like acne.

Carrots

Vitamin A can be found in carrots. According to the Vitamin & Nutrition Center, vitamin A helps to reduce production of sebum, a natural oil made by your body. Excess oil on your skin can lead to potential acne formation. Vitamin A also aids in your body's ability to deal with stress -- a factor of acne development in some individuals. A deficiency in vitamin A can cause acne.
