Article: Cotton and linen are the most breathable fabrics, and they let sweat evaporate instead of forming a layer on your chest that clogs your pores and invites bacteria to grow. Eat a handful of walnuts every day to reduce skin inflammation. Eat more fruits and vegetables. Get lean protein, such as poultry breast or soy, into your diet, along with whole grains and omega-3 fatty acids. People who eat more fruits and veggies, and less milk and sugar, tend to have less acne. Make sure you get 5 to 9 servings of healthy vegetables (especially leafy greens) per day. Healthy fats, like omega-3s, help fight inflammation and promote healthy cells. Omega-3s are damaged by oxygen, meaning if you eat foods that are rich in omega-3s, try to eat them raw. Foods rich in omega-3s include: Fish, particularly salmon, sardines, and herring. Seeds and nuts, particularly flaxseed. Leafy greens, particularly spinach and arugula. Your skin is the largest organ in your body. Like other organs, it needs plenty of water to stay hydrated and functioning on a healthy level. Many doctors recommend that you drink between 9 and 12 cups of water per day (2.2 to 3 liters), depending on whether you are a girl or guy. Cut sweet, sugary drinks like sodas, juices, and smoothies out of your diet. Although the evidence has been disputed for decades, new reports seem to indicate that diets do have a substantial effect on acne, listing sugar as a trigger. Sugars cause a spike in insulin, which in turn stimulates a certain pimple producing hormones. Unsweetened green may work, too. Green tea contains antioxidants that help fight free radicals; free radicals affect the cells that may be responsible for signs of aging in the skin. For a healthy alternative to water, brew some tasty and healthy green tea! Dairy products contain hormones from cows, and these hormones stimulate your pores and your oil glands. If you have to drink milk, choose skim milk. The hormones are largely concentrated in the fatty portion of the milk, so drinking skim will limit your exposure. Look for labels that say "non-comedogenic" or "oil-free." Comedogenic ingredients have a tendency to clog pores. Comedogenic ingredients include cocoa butter, pigments and dyes, coal tar and isopropyl myristate. If your skin is oily, you should always look for non-comedogenic lotion and cleansers. If you have germ-ridden hands and then touch your chest, you transfer bacteria onto your chest skin that can clog your pores. So wash up. You'll not only prevent acne but also a variety of diseases. Doctors aren't completely sure why, but they do know that there is a link between stress and skin disorders, specifically stress and acne. Somehow, the cells that produce sebum, which is the stuff that ultimately causes acne, become unregulated when a person experiences a lot of stress. Get plenty of rest. Doctors know that the less you sleep, the more likely you are to experience stress throughout the day. And the more stress you experience, the worse your acne gets. Exercising is almost a universal panacea. In this case, exercise promotes healthy circulation and helps ease anxiety and stress. So find an excuse to run or walk around the block, join an intramural sports team, or hit the stationary bike. Shower after you exercise. This is very important. Your pores may be clogged with sweat after you exercise. If you shower and clean them, there's a good chance that you might avoid some of the chest acne that is caused by simple neglect after exercising.

What is a summary?
Wear cotton or linen tops. Change your diet. Drink plenty of water. Skip dairy products. Use non-comedogenic body lotion to prevent additional breakouts. Wash your hands after you go to the bathroom. Remove as much unhealthy stress from your life as possible. Exercise.
