The reason why acne shows up is because waste toxins and sebum build up in your system. Many people do not know that is the cause of acne.
Your body has 4 channels of The bowels, kidneys, skin, and your lungs. Your bowels and kidneys are the most important channels that your body gets rid of product waste and toxins through. When your bowels and kidneys get too much waste products, your body tries to get rid of them through your lungs and skin.
Without water that can't happen because water has a very important task which is carrying the nutrients around the body. If you had nothing but fizzy drinks and no water for a whole week, your acne will incredibly worse.
When you drink water it makes it easier for the body to flush out any unwanted waste and toxins. These toxins will eventually leave your body giving you a much better feeling on the inside of your body. When the waste in your body leaves it will take the sebum with it which is great. The reason why getting rid of the sebum is great is because sebum is the root reason why people have acne. The hormones start to get imbalanced and it starts to mass produce a product called sebum. When the sebum tries to get out of your body through your skin, (which it cant) it creates discolored spots what are called acne.
With at least 8 cups of water a day, you will be able to keep away all the bad toxins, waste and sebums.
