Note from Lauren: I invited my friend Melissa Gallico to share this eye-opening article with you today. Melissa is doing incredible research and education around the health effects of fluoride, and heads up a petition to ask Congress to stop promoting fluoride.
Additionally, this is the filter I use to remove fluoride from my drinking water. It’s the most affordable and accessible option I’ve found for fluoride removal.
Acne is the most common skin condition in the United States, affecting an estimated 50 million Americans each year. Yet when it comes to identifying the root cause of this common condition, many stones are still unturned.
In 2002, researchers at John Hopkins University conducted a review of the scientific literature on acne from the second half of the twentieth century and found that 99.6 percent failed to even mention diet.[1] Since then, thanks in large part to the paleo movement, more researchers have focused on the dietary causes of acne. However their studies mostly center on sugar, the primary culprit in obesity and heart disease.
None of these researchers focus on fluoride as the root cause of the modern acne epidemic. Here are five reasons why they should — and why you should too if you if you are looking for real answers to chronic adult acne.
1. Adult Acne is Non-Existent in Low Fluoride Societies
In their study of traditional societies in the Amazon and Pacific islands, Loren Cordain and his colleagues make clear that entire societies of people never experience acne.[2] Dr. Cordain attributes this phenomenon to their low-glycemic diets which stand in stark contrast to the high sugar diet most westerners consume.
But a more subtle difference is that these traditional societies also consume a diet that is naturally low in fluoride. The mean fluoride content of freshwater is 0.05 ppm.[3] This is fourteen times less than what government dentists recommend for artificially fluoridated water programs across the United States.
The traditional diets described by Dr. Cordain and his colleagues are also low in fluoride because they do not include fluoride-based pesticides or black tea. The camellia sinensis plant used to produce tea leaves is the only edible plant that uptakes significant amounts of fluoride directly from the soil.
2. Case Studies Show Fluoride Can Cause Adult Acne
Topical exposure to fluoride from toothpaste and dental treatments has been proven to cause an acne-like skin condition around the mouth and chin called perioral dermatitis.[4] But ingesting fluoride can cause acne, too. I know this because I struggled with cystic acne for nearly 20 years before I figured out the root cause was fluoride in my diet.
Throughout my career as an intelligence analyst with the military and FBI, I had the opportunity to live in several non-fluoridated countries. It was the experience of moving back and forth between fluoridated and non-fluoridated regions that caused me to first suspect fluoride as the culprit. If my acne was genetic or truly incurable, as some dermatologists claimed, why was my skin effortlessly clear within weeks of moving to certain countries? Through careful analysis and observation, I was able to heal my acne completely by learning how to avoid excess fluoride in my diet.
The reviews on Amazon and elsewhere for my book, The Hidden Cause of Acne, are evidence that I am not the only person with this condition. Below are before and after pictures of Amy Saunders, founder of Skyn Therapy. Even though Amy lives in a non-fluoridated region of England, she was experiencing fluoride-induced breakouts from the fluoride contained in common products like toothpaste and non-stick cookware.

Jennifer Cramer, the Mindful Nutritionista, did not realize the high amount of fluoride she was consuming from homemade kombucha and other sources was causing her skin to break out. When she reduced her fluoride intake, not only did her skin clear, but the ovarian cysts and migraines she experienced on a regular basis also disappeared.

After writingmy book on fluoride-induced acne, I later learned the causal relationship between fluoride and acne was observed decades earlier by an allergist named George Waldbott. World-renowned for discovering the link between emphysema and smoking, Dr. Waldbott spent several years studying people like Amy, Jennifer, and myself who are hypersensitive to fluoride. “Skin eruptions” were just one of the many negative side effects he documented in his patients.
You might be asking, if fluoride-induced acne is so common, why has it been overlooked for so long by government health authorities?
Most dermatologists have not heard of Dr. Waldbott’s double-blind, placebo-controlled studies showing that a significant portion of the population experiences acne from the amount of fluoride added to the public water supply. Negative studies on fluoride have been intentionally suppressed because they run contrary to powerful special interests. There is a reason Waldbott’s book is called The Struggle with Titans.[5]
3. Fluoride Is Not a Mineral Nutrient, It Is Pollution
For decades, proponents of fluoridation have relied on the argument that decades of research prove the fluoride added to water is completely safe for everyone. But when were the decades when they did the actual research?
Fluoride is not a mineral nutrient like calcium. It is a halogen, like chlorine and bromine. The human body has no known requirement for fluoride and, like chlorine, certain forms of fluoride are known to be toxic and highly volatile.
If you look for official comprehensive studies on the longterm safety of artificial water fluoridation, you will soon discover they do not exist. This is because the primary story of fluoride is not about cavities or public health or even science. At its heart, the story of artificial water fluoridation is a pollution story.
In the mid-twentieth century, fluoride was a leading air pollutant.[6] A common element in the earth’s crust, fluoride is a toxic byproduct of many industries, from aluminum plants and fertilizer factories, to brick and tile manufacturers. At the time artificial water fluoridation was first being studied as a solution for dental decay, corporations were facing litigation from coast-to-coast regarding damage caused by fluoride pollution to agriculture, livestock, and human health.
To mitigate their vulnerability to lawsuits, these same corporations funded studies at university research centers to prove that fluoride is safe. They even joined together to form a self-described “Fluorine Lawyers Committee” and hired their own medical advisory board to direct university researchers.[7]
Dentists who supported fluoridation had their research funded and were promoted to positions of authority while those who voiced opposition or urged caution were ignored or forced out. A corporate-funded dentist was the first to propose adding fluoride to the water supply, and a lawyer for the biggest polluter was head of the U.S. Public Health Service when fluoridation was prematurely endorsed by the federal government. At the time, government dentists were only 5 years into a 15 year trial to prove fluoride’s efficacy at reducing dental decay.
After extensive damage to livestock and agriculture, EPA now sets strict regulations prohibiting the release of fluoride pollution into the atmosphere. Instead, this same toxic “byproduct” of industry is packaged and sold to municipal water utilities for addition to public water supplies.
Approximately 90 percent of the fluoride added to water is a byproduct of the phosphate fertilizer industry.[8]
4. Fluoride Affects More Than Just Teeth
Government authorities advocating for fluoridation argue that the dose makes the poison, and that the amount of fluoride added to water is too small to cause harm. They are quick to point out that fluoride is naturally occurring in some water supplies, and that artificial water fluoridation programs are merely adjusting the level to the dose they deem optimal.
But as our tragic history with other natural but toxic elements like lead and mercury demonstrates, government regulators have a tendency to underestimate and oversimplify the risk to public health when large financial interests are at stake.
Individual reactions to fluoride depend on a variety of factors. It is well established that fluoride bioaccumulates in bone and can cause symptoms of arthritis over time. The National Research Council estimates the half-life of fluoride in human bone is twenty years.[9] That means half the fluoride sequestered in your bones today will likely still be there twenty years from now. I suspect one of the reasons I am hypersensitive to fluoride is because my dentist prescribed a fluoride supplement for me as a child when my teeth and bones were developing.
Other signs the indiscriminate dosing of fluoride through the water supply is inappropriate include the fact that fluoride is a known endocrine disruptor. It has also been shown to depress thyroid activity and has even been used as a drug to treat hyperthyroidism.[11] The highest concentrations of fluoride in the human body were found in the pineal gland, a brain organ that produces melatonin and regulates sleep.[12]
In 2015, researchers at the National Toxicology Program within the Department of Health and Human Services proposed a study to evaluate the neurotoxic effect of fluoride on children, writing “the existing literature is limited in its ability to evaluate potential neurocognitive effects of fluoride in people associated with the current U.S. Public Health Service drinking water guidance.”[13]
5. Observing the Effect of Fluoride on Adult Acne is Easy
Even if you are skeptical of the scientific argument against artificial water fluoridation, it is easy to test for yourself if your adult acne is caused by fluoride. Simply switching to fluoride-free drinking water and toothpaste for one month should be enough to see a dramatic reduction in breakouts.
If you notice improvement, the next step would be to eliminate other excess sources of fluoride from your diet, such as black tea, food and beverages made with fluoridated water, and the common culprits for fluoride-based pesticides.

I just switched toothpastes a week ago, using a fluoride Colgate brand. Within two days, I had lower lip perforation and perforation of skin on the sides of my mouth at the chin. It looked terrible. I immediately stopped with the toothpaste and a lip balm that I had introduced to my daily routine three weeks before. I am happy to say that the lip perforation has subsided 90% after 5 days of non use. But I still am aware of the darkness and perforation on the chin area.
I am quite happy Lauren chose to share this article. I will be joining the fluoridefreefaces group and staying abreast of all literature on this insidious chemical. What a threat!!
Switching toothpastes is a good start but you should definitely look into getting a reverse osmosis water filter. The biggest damage caused by fluoride is from the fluoride we consume in our water. Think about it – if using fluoride toothpaste was causing so much damage to your lips, imagine what it must be doing to your insides…
What about glass isonomer cement filling that release fluoride?
Excellent article, Lauren – so glad to see the word is getting out. Thanks to Melissa, I discovered fluoride is a huge contributor to my problem. I now avoid it all costs but always know when I make a mistake. My water is not fluoridated at home, but just a road trip 45 minutes to another state caused me two weeks of grief over the summer. And I currently have two cysts because I forgot to ask for no ice at the bar at a wedding in another state over the weekend.
Hello!
I’m a big tea drinker and super curious to learn more about the fluoride in black tea. Do you have any more information about this? Thanks!
I too am wondering about black tea. I am a huge tea drinker and this has me thinking!
I am also a black tea drinker and I gave up tea after learning about it’s fluoride content from Melissa. It’s only been a week — not enough time to see if it’s made a difference with my skin.
I too have found that I am hyper sensitive to fluoride. Months ago I switched to a gum strengthening toothpaste. I also got Invisalign braces the same time. My face became swollen and heavy breakout almost hive reactions started. I switched face cleansers, soap, makeup, everything I could. Finding a slight allergy to the latex bands in my mouth, I thought that would solve it. It took down the swelling but the rash and breakouts near my mouth got worse, and spread to my cheeks and forehead. One morning I looked at my toothpaste and noticed the fluoride level seemed high. I compared it to my husbands normal brand and it was over twice the amount. Keep in mind, with my braces, I was brushing my teeth and Invisaligns up to 5 times a day. I was poisoning myself!!! I went and tried a fluoride free natural toothpaste and within hours I was feeling better. In a couple days all my hives disappeared. It is a real thing, and dangerous. Your body trying to fight off the toxin is a constant drain. Thank you for your article, bringing awareness!
Thanks for your amazing research! Whenever I travel to remote places, my acne does not exist. I currently filter my water with a Berkey filter that has fluoride filters. Do you think that it’s strong enough?
Yes, that’s the filter I use and it is thorough in removing fluoride. You might also be impacted from the fluoride in your shower/bathing water, but I’ve not found an accessible option to remove that.
I have found shower filters and bath filter balls at PCC. You may also be able to find them online and other natural co-op grocery stores. I’m sensitive to fluoride and they help me! Hope this helps!! 🙂
Hi, what toothpaste would you recommend?
Dermalmd has to be the best cystic acne product I’ve ever found. I use this after I use the face wash. It took less than 5 days to begin to see the acne clearing up.
You are correct. Fluoride causes chronic acne. Traveling to locations with unfluoridated water causes an immediate improvement. Using/not using toothpaste with fluoride turns the eruptions on and off like a switch. Also, soaking in an epsom (magnesuim sulfate) salt bath up to my chin made a noticible improvement, so I searched for ‘treatment for fluoride toxicity magnesium’. Guess what the effective treatment for fluoride toxicity turned out to be?

A simple, safe, and efficient way to treat severe fluoride poisoning–oral calcium or magnesium
The second thing that helped was some goat milk soap (thank you bend soap co) and tea tree oil.
I’m not sure if it is what is in the soap or what is NOT in the soap, still researching that. But the tea tree oil, there you can go back to pub med and find articles with concentration of tea tree oil vs % kill vs time for different bacteria, including MRSA, and mites, including the ones (demodex) that normally live in your eyelashes but can get out of control and cause skin irritation, including possibly rosacea-like symptoms.

My bet is that the skin irritation/acne is the result of a combination of stresses, the fluoride, irritants in the soap you are using, maybe some resistant bacteria, and dry skin which compromises the integrity of this barrier. Remove the fluoride, throw some epsom salt in your bath, read the ingredients on the Bend soap and buy that or something with similar ingredients, and try a small bottle of tea tree oil, and get on your way to happy skin. Hope this helps.
Appreciate how you take an analytical approach to assimilate information and come to some essential and novel conclusions. Further reading leads to the conclusion that some adult acne is not the only detrimental effect of fluoride. Keep up the good work.
I’ve had an issue with fluoride and adult acne for years and found turmeric (curcumin) supplements with black pepper help to detox fluoride from my body.
Also, for years I tried to avoid all types of fluoride, naturally occurring calcium fluoride found in tea and shrimp and the chemical compounds like sodium fluoride from pesticides. It turns out my breakout only happen with the latter. Hope this helps.
Laura, when I find articles like these (which seem to be far and few between) it is incredibly validating for me!! Thank you so much for posting this information and putting it out there! Maybe one day the world will listen!
I am allergic to fluoride, my symptoms began when I was about 15. The doctor I went to see put me on medication to help control the inflammation and this terrible rash that had popped up around my mouth and nose. It wax itchy, painful, dry, and kinda blistering/oozy. This doctor also sent to an allergist who determined that I was allergic to fluoride and that was what was causing of all of my skin issues. This was in 1999. Back then, it was pretty difficult to find fluoride-free toothpaste in the tiny town where in from, but we managed and found one shop in the whole area that I started purchasing all my toothpaste from. It worked, the rash went away, and I was seemingly fine.
Growing up, I lived in a rural mountain area, and the water there didn’t affect me. I did not know that it could even be a factor. Fast forward about 9 years when I moved to Houston, TX and my skin freaked out. Again. Worse this time. It started as a couple here or there and eventually, became all the time. It was no longer a rash, but more cystic acne and peri oral dermatitis. I spent years on doxycycline, tons of money on special face washes, religiously cleaned my face and tried not to touch it, switched out all of my makeup products. Everything they suggested. I had to go in and have my bloodwork checked every month to make sure I could handle the medications for my condition (that’s how bad it was for me, I would do anything for my vanity, it seems silly now but I’d probably do it again if my face were still there now!) I drank water from my fridge, and although it was filtered, I was still drinking city water. I had wondered all along if it was perhaps the fluoridated city water that was triggering my issues, and man, I wish I had listened to my instincts.
After ten years of this, and my face being destroyed my scars, picking, and trying to cover up the blemishes with various products, my husband and I moved to the outskirts of Austin TX to a home that was on its own watering well. And guess what- my face instantly cleared up!!! I was shocked but also convinced that my hunch was spot on more than I had ever been!! If only I had known while I was in Houston!!! It took moving away and being on a different water system to figure it out and be 100% confident that this had been the issue all along. I stopped taking the meds, I stopped the face creams. My skin was as flawless as it could be, considering the previous damage that had been done to it. No more break outs! No more flare ups! Except when I’d travel- again, another validation of my self diagnosis.
A few years ago, I moved to downtown Austin and attempted to drink the water from my fridge (I had yet to be on this city’s water system, and in certain places where I traveled, it would be fine). Cystic acne immediately commenced within a week of living there. Since I no longer had access to well water and could not buy a special water filter to install for the whole home, I began my research into bottled waters without fluoride (there aren’t many- Aquafina is the one with the least trace amount that I can find, and my skin tolerates it). They do not however, have a home or bulk delivery service like other water services such as Ozarka (which breaks me out). I was so stressed and saddened that I was in a bad position again for my skin. Its not feasible to drink individual bottled waters for the rest of your life, so I knew I had to find a solution, or I would only suffer more.
I, like you, researched and researched and researched until I decided upon a Berkey water filter with fluoride filters. It is the best!!! It’s been a face saver and life changer for me!!! I highly recommend to ANYONE who is considering! I am in the clear, it definitely does what it says, and I have no problems!! I fill up a container and keep it in my fridge so that I can enjoy room temp and cold water like a ‘normal’ person still haha. I brush my teeth with this water and I wash my face with it. I bathe and shower in the city water, I just do not ingest it or put it on my face without filtering through my Berkey first.
My tips to those who are traveling/on the go or don’t have the convenience of your water filter are:
-fill up a canteen and take it with you if/when you are going out to eat. This is how I avoid drinking city water at restaurants (if they have bottled water- not just filtered- I will drink theirs sometimes).
-When I’m out of town or vacationing, the simplest and easiest way to avoid ‘testing out’ foreign areas’ water is to buy a gallon of distilled water. It’s safe for my skin and has nothing added to it! Since babies and devices need distilled water, it’s always available unlike some bottled water brands you may be able to depend on the store having at home, but not in another state or country.
I have been doing this for the past four years, and it has proven my best method so far. No more medications, no more acne creams, no more doctors visits, no unnecessary diet changes, and no problems!!!
To think, of all the money, time, tears, pain, itchiness, shame, scars, and embarrassment I have been through… all because of the water I ingested and thought was fine and safe to drink. I could have saved so much more if only I had known or even one doctor had believe or suggested that this was a possibility.
I have had a life-long struggle with this particular issue and have tried several remedies over the years. It took me about 15 years to realize, byway of a process of elimination, what was going on. I share my story here so others can benefit from the info and advice or find solace that they are not alone or crazy in thinking this to begin with. (It’s a hard conversation to have with strangers when you tell them you’re allergic to water, lol, like wtf!)
We really are what we put into our bodies! It was a simple (albeit long) solution as that for me and I hope it will be for you too!
Fluoride has been a part of our water supply since the beginning of time. It was introduced as an industrial product in the 1950s and immediately began to be used to treat teeth (and it was found that the benefits were not only cosmetic but also had health benefits). As I’ve written about before, there is very little evidence that using fluorides in your water supply makes you healthier. The main reason they are used in this way is because of an irrational fear. While there are many things you can do to eliminate your fear and make you healthier, there is nothing short of complete and undiluted love for yourself that will fix your fear about fluorides.
