If you had acne problems, I feel sorry for you. I mean there is nothing worse than the social rejection suffered by those with less than average complexions. The especially sad part is that there was nothing that they could do to prevent it. And on top of that some people suffer from the indirect consequences of acne that can go with a person for the rest of his life.
Now because the problem is so important in so many ways it is easy to see why there has been so much effort put into learning about the problem and trying to solve it. There are a ton of different ways offered to cure acne and some are a lot more worthwhile than others. These cures range from spreading disgusting mixtures of organically produced potions to ultrasonic technology that "zaps" the gland that is producing the offending inflammation.
That is what acne is by the way, inflammation that starts deep down in the dermal layer, that attracts all sorts of different immune competent cells to make the pain, redness, swelling, and pus that you find with acnes. It would be great if we new what turned the "switch" on to this inflammation– but the fact is that we do not. We know that several factors bring it on, a major one being puberty and all of the changes especially the hormonal ones that start circulating through the body. Another major focus is the dirt and oil that get on your face during the day and that you grind in on your pillow at night that is clogging the pores and producing the crops of zits. Another think is the foods that we eat namely foods high in oils, sugars, and chocolate.
The trouble with all of these ideas is that as much as you work to change these factors the chances are that you will not get rid of the painful and unsightly red pus filled pimples. You can wash until the take off the first layer of skin but you won't get rid of them all. You can also stop eating anything good, trying to avoid the foods that supposedly cause acne but if you have any success it will only be partial.
So obviously we haven't found what is at the root of the problem but that doesn't mean the effort isn't there. So my recommendation at this point is to get a doctor that will take the time to get to understand who you are and what methods would be most effective for your particular strain of acne. They have access to the best training and information and they are in the best spot to start working with your individual case and hopefully make your life a lot better.
