When teenagers (or anyone else for that matter) drink milk from cows, they unknowingly take in a dose of saturated animal fat, dead white blood cells (cow puss), cholesterol and steroid hormones.  

2) Diet
Many studies have been done that clearly show that people living on their traditional native diets do not have this problem.  You can get rid of these skin problems by changing your diet.  Many have done this.  This is by far the most effective and lasting home remedy for acne.

3) Vitamins
Vitamin A, zinc and niacin are two vitamins and a mineral that have been shown to be an effective in eliminating this problem.  For the period of one month, take 50,000 units of A, 50 mg of zinc and 100 mg of niacin three times a day.  After one month discontinue for one month.  Then the regemine can be done again for a period of a month and so on.
 
4)  Oatmeal
Make a regular bowl of oatmeal as if you were going to eat it.  Add a fourth cup of honey and stir in well then let it cool.  Pack this onto your face like a mud pack while keeping it out of your eyes.  After about 20 minutes you can wash it off.  This will greatly improve your condition.
 
5 Mint & Turmeric
Juice fresh mint leaves and mix with turmeric powder. Apply this as a paste to the affected areas and leave for 15 minutes before washing off.

6) Aspirin
Here is a good acne natural remedy to remove the swollen red look of unsightly pimples.  Take a couple of standard aspirins and crush them into powder.  You can do this with a spoon.  Then mix just enough water to make a lose paste.  Put this on the problem areas of your face before you go to bed and presto in just a few days you will begin to see much improvement.
 
7) Oatmeal
Make some oatmeal but first put a couple of teabags of peppermint tea and a couple of bags of plain old black tea in the water and bring the water to a boil.  Now put in a tablespoon of Epsom salts.  Then add the oatmeal and let it sit for a few minutes.  Put the mixture on the pustules and pimples for about a half hour.  You will start to see a big difference in just a few days!
