I take it for granted sometimes, but I think it’s so cool that we have such an active, helpful, supportive community of people on Acne.org sharing their knowledge and experience.
So in the spirit of Thanksgiving, I just wanted to say thanks to all of you who are active here at Acne.org, whether that be through adding your honest review of products or treatments you have tried, or whether it is asking and/or answering questions on the forum, uploading pictures to the gallery, or keeping a blog of your experience with acne treatment.
How much do we all rock?! A lot.
A long overdue page on the particularities of male acne is now live. Check it out!
I recently found out about a group of students at the University of Pittsburgh who wanted to work on acne bacteria in an attempt to get it to the point where we can experiment with genetic engineering on these bacteria that have a hand in acne.
When I first pledged money they were only about half way there. As of yesterday I found out they are fully funded! Fantastic guys. Rock it out!
You can view more about this research here.
Acne rosacea is a different disease from acne vulgaris (run-of-the-mill acne). However, since symptoms often overlap, I like to keep on top of rosacea research as well. A few years ago I read a truly fascinating study which found that the guts of people with rosacea had a much higher incidence of bacteria colonization with a type of bacteria called H. pylori (helicobacter pylori), the same bacteria that is responsible for the majority of stomach ulcers. Of the people who had this bacteria, 20 of 28 of them appeared to be cured by using a powerful antibiotic to specifically kill the helicobacter pylori bacteria. I got so jazzed from the possibility that perhaps H. pylori could also affect acne vulgaris that I went to the doctor and had him order an H. pylori test for me. The test took hours and involved me blowing into a detector every few minutes. My results: Negative. I didn’t have any H. pylori in my gut.
Another study has since been conducted in Nepal. The researchers found that 17 out of 26 rosacea patients they studied had colonies of H. pylori in their gut.
This evidence is so compelling that rosacea researchers are starting to look at the possibility that rosacea is simply a skin manifestation of an internal disease of the gut.
Might another existing or still undiscovered gut bacteria cause or aggravate acne vulgaris? I would so love to know.

Medical science is still not close to deciphering what causes acne, but it’s not for lack of trying. Here I will summarize 9 recent studies that I have read which attempt to get to the bottom of it. Keep in mind that we have no definitive conclusions, just ongoing research. Warning: Big words!
Oxidative stress. Scientists published an article in the Journal of Drugs in Dermatology considering the role of oxidation as something that “may be an early event that helps to drive the acne process.” Could it be skin oil (sebum) oxidizing that causes acne? Could antioxidants help?
Growth hormone and IGF-1 (Insulin-like growth factor 1). A study in Iran attempted to evaluate the power of growth hormone and IGF-1 to affect male hormones and thus increase the severity of acne. “The mean serum levels of GH and IGF-1 of severe acne patients were significantly increased when compared with mild-, moderate acne patients, and healthy controls.” A second Turkish study further evaluated the link between IGF-1 and acne. Again a significant link was found between IGF-1 levels and acne severity.
Staphylococcus aureus (S. aureus). You may have heard of this in regards to “staph infections.” In the journal North American Journal of Medical Sciences, researchers looked at the Staphylococcus aureus levels in acne patients vs. healthy controls. Results were inconclusive. “S. aureus was detected in 21.7% of the subjects in acne, and in 26.6% of control groups.”
Altitude. An article in the European Journal of Pediatrics looked at 6,200 boys. Interestingly, they found that “the acne frequency decreased with the increasing of the altitude where the boys lived.” Why this might be the case we don’t know.
Inflammation. Three articles looked at inflammation more closely. The first in the Journal of Drugs in Dermatology further elucidates the particular sequence of inflammation that leads to acne lesion formation. “An important facet of the new paradigm is that a specific follicular pattern of innate inflammation occurs before and during follicular hyperkeratinization. Moreover, this inflammation persists during the resolution of the macular phase after inflammatory lesions flatten toward the end of their life cycle.” A second article in the Journal of Drugs in Dermatology further states this point, “Newer research has shown that inflammation may precede comedo formation. Gene array analysis of acne lesions has elucidated newer inflammatory mediators…” A third study, again published in the Journal of Drugs in Dermatology drives home the point, “Recent evidence suggests that subclinical inflammation is the primary event in lesion development and that inflammation persists throughout the lesion life-cycle. Therefore, all types of acne should be considered ‘inflammatory’ acne.”
Genetics and Lifestyle. An study performed in Italy and published in the Journal of the American Academy of Dermatology looked at family history, personal habits, diet, and menstrual history. Their conclusion: “Family history, body mass index, and diet may influence the risk of moderate to severe acne. The influence of environmental and dietetic factors in acne should be further explored.”
Thanks scientists for all your work! Hopefully we will keep getting closer to figuring out what causes acne so we can get to the root of it and wipe it out for good!

TAKE THE QUIZ
I’ve noticed over the years that anything I read about acne in magazines is usually replete with errors and terrible misinformation. I’m at my dad’s house for a few days right now and my step mother gets Fitness magazine. The cover claims “Clear Skin Breakthroughs That Really Work.” I had to crack it open and read it. Their advice boils down to using salicylic acid and perhaps staying away from milk. Wow. Such bad advice. First of all, anyone who researches acne to any degree knows that salicylic acid is very weak at controlling breakouts. The legal limit for salicylic acid products is 2% and at this concentration it does very little if anything to help clear the skin. And milk has been associated with breakouts in only very limited, confusing studies based on people recalling what they ate many years previously. This evidence is so flimsy that the authors in The Journal of Clinics in Dermatology concluded, “Our conclusion, on the basis of existing evidence, is that the association between dietary dairy intake and the development of acne is slim.”
I could go on and on here picking apart the deep horrendousness of this one supposed “Clear Skin Ahead” article as it is titled inside the magazine, but suffice it to say that this article will do nothing for anyone other than cause them frustration and confusion. This is true of upwards of 90% of other articles I have read in major magazines over the years. Can you tell I’m mad? Well, I am. Ok, I just have to quote one more thing from this article. Haha. Keep in mind that almost every journalist who has ever interviewed me has misquoted me, so I’m not dogging the doctor here. But they quote a doctor saying, “sweat and bacteria left on the skin after a workout can be a breeding ground for breakouts…” The reality is that bacteria on the surface of the skin has zero to do with acne. Zero. It is bacteria deep within the skin which causes acne. Far from clearing things up for the readers of Fitness magazine, this quote just reinforces yet another myth about acne.
Bottom line: Don’t believe pretty much anything you read in magazines about acne. And to extrapolate, don’t believe pretty much anything you read in magazines period.
I live in San Francisco where the weather is almost always temperate–cool with low humidity. However, I am in Pennsylvania right now visiting family. I forget how unforgiving hot, sticky summer weather can be to acne-prone skin until I am enveloped in it. I’ve had to be super strict with The Regimen since I’ve been here to stay clear. This is par for the course in hot, humid weather, however. Researchers have found that people in hot and humid climates have more incidence of acne and more severe cases of acne than those in temperate climates. This is not to say that you can’t still stay clear during summer. It just takes stricter adherence to The Regimen.
Tips to stay clear in hot/humid climates:
1. If you end up sweating, try to be gentle when you dry off. Dab your skin gently with a towel or napkin and do not rub the sweat off. Constantly wiping off sweat can be irritating to the skin and cause a breakout. More tips on how to avoid irritation here.
2. Be super strict with The Regimen. Do it twice a day, every day, use plenty of benzoyl peroxide, and moisturize even if you don’t feel that you need to. In the summer it is even more important to follow The Regimen to a T.
3. Try adding 10% glycolic acid (AHA) to The Regimen to bump up the effectiveness even more. Just be sure to adequately protect your skin from the sun if you decide to add in glycolic acid.
4. Since body acne can be aggravated by irritation, and sweat + irritation can make this worse, you may need to treat your body in the summer as well.
Now go out and have some fun!
