In my experience, having clear, radiant skin is an inside job! As a holistic nutritionist, I work with lots of clients to help them get rid of their acne for good. They come to see me because they realize that something about their diet and lifestyle is inflaming their skin and causing their breakouts.
From a holistic perspective, all of our body systems are interconnected so if one system is out of whack, it influences others. With acne, the underlying cause is likely to be one or potentially all of the following: hormonal imbalance, liver congestion, and/or gut inflammation. For today’s post, I am going to hone in on women’s hormonal imbalance, but we can’t talk about hormones without addressing the liver and gut!
Acne’s Underlying Causes
- Hormonal Imbalance – If your period is all over the place, it’s a sign something is off with your hormones and your skin may be suffering as a result. If you don’t have regular cycles, or your cycles are very symptomatic (i.e. headaches, bloating, cramps, intense cravings, etc.) particularly during the premenstrual phase, then working to balance your hormones is key.
- Liver Congestion – Our skin is our biggest organ of elimination. It works within a system that includes the liver, kidneys, lymphatic system and large intestine. Everything that goes into your body (food, water, air, skin products, household cleaners, etc.) must be filtered by the liver and eliminated properly. If the elimination organs aren’t working optimally, toxins have to come out somewhere, and unfortunately, they can show up on your face as acne.
- Gut Inflammation – Even if you don’t have overt gut issues (like frequent diarrhea, gas and bloating), you can still have underlying inflammation in the digestive tract. Leaky gut, dysbiosis and inadequate production of stomach acid and pancreatic enzymes can all lead to increased intestinal inflammation, which is a major root cause in acne.
Hormones Involved in Hormonal Imbalance and Acne:
The five hormones below are major players when it comes to acne.
- Estrogen – High estrogen in relation to progesterone (AKA estrogen dominance) is a root cause in many hormonal imbalance conditions, such as PMS, PCOS (polycystic ovary syndrome), and endometriosis. Estrogen dominance can be caused by i) exposure to xenoestrogens which are toxins that mimic estrogen and wreak havoc on your endocrine system and; ii) inadequate estrogen clearance due to sluggish liver function. If your liver is overworked dealing with other toxins, estrogen does not get properly metabolized and detoxified and therefore can be re-circulated back into your system. High estrogen causes skin inflammation and acne.
- Progesterone/Testosterone – Too much testosterone increases the production of sebum in the skin which clogs pores and causes acne. At the skin level, testosterone gets converted into DHT which is a more aggressive form of testosterone that causes an overdrive of oil production leading to more acne. Adequate amounts of progesterone are key because progesterone prevents the conversion of testosterone into DHT; however many women (such as those with estrogen dominance conditions) have low progesterone. So, high estrogen, high testosterone and low progesterone create a perfect storm for acne, which is why acne is so common in women with PCOS.
- Insulin – Insulin is the hormone that gets secreted by the pancreas to shuttle glucose into our cells to be used as fuel. A diet full of sugar and starch leads to high insulin levels which catalyze acne in a variety of ways. High insulin will increase inflammation and testosterone, leading to more oil production and thus more breakouts.
- Cortisol – We know cortisol as our stress hormone. One of the mechanisms of cortisol is that it tells the body to release more sugar into the bloodstream which can cause high blood sugar and high insulin. This often leads to increased inflammation and the vicious cycle continues!
Possible Causes of Hormonal Acne
Now that you’ve got the low-down on the major hormonal players, let’s dig into the possible causes of hormonal acne.
- Going off the Pill – Certain types of hormonal birth control suppress acne/sebum production by altering the level of free testosterone in the circulation. Many women are put on the Pill to help their acne or they find that clearer skin is a bonus of being on the Pill. Estrogen stimulates the production of sex hormone-binding globulin that binds to free testosterone, preventing its action on the sebaceous unit. Unfortunately, it is not uncommon for women’s acne to come back with a vengeance after going off the Pill. Post-Pill acne is the result of 1) rebound sebum production due to an increase in free testosterone 2) rebound androgen (male hormones like testosterone) production from your ovaries. This rebound effect after getting off the Pill can last a few months while your hormones work to regulate themselves. The worst time for acne is typically about 3 months after stopping the Pill. As long as your period returns (and your body starts making its own natural estrogen and progesterone again), acne should subside.
- Polycystic Ovary Syndrome (PCOS) – Many women with PCOS have high insulin, estrogen dominance and/or elevated testosterone which increases sebum, skin inflammation and acne.
- High Insulin/Insulin Resistance – Insulin activates insulin growth factor (IGF-1) which increases sebum, keratin and inflammation, the three enemies of clear skin!
- Food Sensitivities/Inflammatory Foods – Acne, at its root, is an inflammatory condition so it’s made worse by consuming inflammatory foods such as gluten, dairy and sugar. While those foods are typically “the big three,” there are a handful of other common inflammatory trigger foods, such as corn, soy, eggs, peanuts, coffee, alcohol, etc. Identifying your personal food sensitivities is important for balancing your hormones and reducing inflammation.
Conventional Acne Treatment
The problem with standard acne treatments is that they do nothing to target the root cause of the problem. Instead, they are masking the symptoms and, in some cases, causing more harm than good.
- Birth Control Pill – More often than not, women suffering from acne in their reproductive years are prescribed the Pill. For most women, taking the Pill helps reduce breakouts by providing a big dose of synthetic estrogen and progestin and ramping up sex hormone-binding globulin (SHBG) which lowers testosterone. Because the overall production of hormones is lower due to the pill’s effect on ovulation, the result is improved skin.
- Spironolactone – This medication is the same drug that is used in the birth control pill Yasmin. It suppresses androgens and inhibits sebaceous gland activity which reduces acne formation. My issue with spironolactone is that, similar to the Pill, it disrupts ovulation, estrogen metabolism and adrenal function. And it comes along with possible adverse side effects such as IBD, menstrual irregularities, loss of libido and depression. It’s not the worst choice, as studies show long term use appears to be safe, but as I said, I’d rather work on addressing the root cause instead of using drugs to suppress hormones.
- Accutane – Avoid at all costs! Its mechanism is to alter DNA expression and can cause serious side effects like IBD, osteoporosis, depression, etc. It’s evident how hardcore of a drug Accutane is by the fact that women must take the Pill when using Accutane because it causes birth defects. Scary!
- Topical treatments, like Retin-A, benzoyl peroxide and salicylic acid, etc. cause skin cell turnover but can also cause skin sensitivity (redness, flakiness, etc) and put more of a burden on the liver to detoxify these harsh chemicals.
Functional Nutrition Diet and Lifestyle for Acne
I work with a holistic and natural approach to treating acne. Whenever a client wants to clear her skin, I use a three-pronged approach:
- Balance hormones – sex hormones (estrogen, progesterone, testosterone), insulin and cortisol
- Heal gut
- Support liver detoxification
Before we get into these three in more detail…just a quick note to women who are on the Pill and worried about getting off and getting your acne back. However, if you are on the Pill for contraception, do not stop until you are placed on another form of contraception.I recommend starting the below treatment a couple months before stopping the Pill. That way, your skin will be less reactive and better equipped to withdraw from synthetic hormones.
How to Balance Your Hormones
Balance Blood Sugar and Reset Insulin
As mentioned above, balanced blood sugar is the first critical step in balancing hormones. You can do this with your diet by eating protein, fat and fiber at every meal. Choose carbs with more fiber, such as vegetables and low-sugar fruits instead of grains and starches. Read my top 10 tips for balancing blood sugar here.
I recommend avoiding inflammatory triggers, such as gluten, dairy, corn, soy, peanuts, processed vegetable oil (canola oil, sunflower, grapeseed, etc.), sugar and alcohol, for at least 3-4 weeks as you begin your skin-healing journey. Removing dairy, in particular, can be a gamechanger. Dairy causes acne because it spikes both insulin and IGF-1. It is also one of the top inflammatory foods due to a protein called A1 casein which stimulates the immune system to produce inflammatory cytokines. Goat’s and sheep’s dairy is less likely to cause acne because they contain very little A1 casein but I still recommend eating these only sparingly. Sugar is another one to limit as much as possible because, like dairy, it spikes IGF-1.
The foods that reduce inflammation and help to clear your skin are low-starch vegetables, low-sugar fruits, wild-caught fish, organic poultry, grass-fed meat and plant-based healthy fats (avocados, nuts, seeds, etc.). Incorporate these 10 inflammation-fighting foods as much as possible.
Managing stress levels is critically important for reducing chronically elevated cortisol which spikes blood sugar and insulin. Remember what happens when insulin is high? Acne. Find any activity that flushes cortisol and makes you feel calm and grounded. Here are some ideas: yoga, meditation, walks in nature, breathing exercises, baths, orgasms, getting enough sleep, etc. Check out this post for more natural stress-fighting remedies. Do one thing every day!
Get Rid of Endocrine Disruptors
These chemicals can be in products that we come in contact with everyday including pesticides, plastics, flame retardants, toys, personal care and cleaning products … even our food and water. Here are my recommendations for reducing your exposure:
- Go organic to avoid pesticides on produce, and choose organic, grass-fed, free-range meat and wild-caught low mercury fish.
- Filter your water to remove contaminants like lead and arsenic
- Ditch BPA by opting for glass food containers and BPA free cans… and don’t touch printed receipts!
- Makeup, lotions, shampoo, etc. contain toxic ingredients such as parabens, triclosan, and SLS. Check the products you’re currently using on the EWG Skin Deep website and swap them out for cleaner alternatives. Or, even better, make your own!
- Clean your house with greener alternatives or blend up your own using natural, non-toxic ingredients like essential oils, vinegar, etc.
Heal Your Gut
In the gut, there is a certain set of gut bacteria and more specifically certain bacterial genes called the estrobolome, that produce an essential enzyme that helps metabolize estrogen. Your gut, therefore, is part of the elimination system that is vital in ushering metabolized hormones out of the body. We want to make sure to keep the estrobolome happy by supporting the health of our microbiome and intestinal lining. Check out this post for my gut health must-do’s. Here are a few ideas to get you started:
- Remove inflammatory foods (see above)
- Add 1-2 tablespoons of fermented vegetables, such as sauerkraut or kimchi, which are rich in beneficial bacteria, to your meals
- Take a shot of apple cider vinegar diluted in water before meals
- Use bone broth to make soups, stews, etc. or drink a cup daily
- Take a high-quality probiotic supplement daily. MegaSporeBiotic is the one I have the most success within my practice.
Support Liver Detoxification
Your liver is responsible for processing metabolic waste, environmental toxins and hormones from the body. If your liver is lacking the nutrients it needs to do its job, over-run with environmental toxins or burdened by a sluggish digestive tract, your hormones will suffer. It is the liver’s job to ready your metabolized hormones for removal by your gut. What happens if your liver can’t do its job? You end up with way more hormones than your body was expecting, resulting in hormonal fluctuations and symptoms galore! Below are some tips to start supporting your liver:
- Fiber – You can support your liver’s ability to process metabolized hormones and toxins by eating plenty of fiber. Without enough dietary fiber, metabolized hormones are secreted into the bile and then reabsorbed in the gut and used again. Fiber increases the secretion of hormones in the stool. A daily bowel movement is crucial! If you’re constipated (and, in my opinion, constipated means less than once/day) then supporting liver detox is where you want to start. My favorite way to boost intestinal motility and remedy constipation is eating 2 tablespoons of ground flax seeds daily.
- Bitter greens – like endive, dandelion greens, broccoli rabe, escarole, spinach, mustard greens, and kale. These leafy greens activate bitter receptors on the tongue, which in turn activates cells in your stomach to normalize acid production for better digestion. When this happens, bile production and digestive enzyme production are improved as well. Proper bile production is liver health, hormone balance, and bowel regularity. Digestive enzymes are essential for extracting and absorbing nutrients from your food. They can also help to reduce the number of unfriendly bacteria in your intestines.
- Detox herbs – burdock, dandelion, sarsaparilla, nettle, etc. are wonderful detoxifiers. I have a delicious Detox Tea which includes all of these plus a handful of others! Drink one cup daily to support liver health and hormone clearance.
- Do a gentle food-based cleanse. Start with one of these: 1-day cleanse and 3-day cleanse. I have a 3-day Cooling Cleanse which is perfect for summer!
I recommend consulting with your healthcare provider before starting any new herbs or supplements.
- High-quality multivitamin/mineral – this covers your nutritional bases and provides your hormones and liver with the raw materials (like B vitamins, zinc, etc.) they need to do their jobs properly!
- Probiotic – a professional-grade probiotic supplement will supply beneficial bacteria to support your estrobolome.
- Omega-3 Fish Oil – reduces inflammation and provides nourishment to your brain, heart, joints, hair, skin and nails.
- Vitamin D3 + K2 – helps regulate hormone function. I recommend asking your doctor to check your levels (simple blood test) before supplementing. Optimal lab range is 50-70.
- Magnesium – miracle mineral for hormone balance. It improves the function of insulin and aids in the manufacture of steroid hormones (estrogen, progesterone, etc.). It’s also wonderful for soothing the nervous system and supporting good sleep.
- Zinc – reduces keratin, kills bacteria, reduces inflammation and lowers androgens.
- Berberine – natural antibiotic so it kills the bacteria in pimples. It reduces inflammation, lowers androgens and improves insulin sensitivity. Particularly good for women with PCOS. One clinical study found that just four weeks on berberine improved acne by 45%. I do not recommend taking berberine for more than eight weeks continuously. If you need it for longer, take a week off then resume. Make sure you consult your doctor before starting berberine as it can interact with medications.
So using this three-pronged approach… How long until your skin improves?
You might see an initial improvement within a few weeks, but don’t worry if your skin then flares up with stress or your cycle. Real, lasting improvement is a longer-term project and typically happens within 3-6 months. I know that seems like forever when you’re desperate to be acne-free, but working to correct the above systems takes some time. I recommend continuing the above recommendations until your skin is truly better, and then you can wean off the supplements and relax on the diet somewhat… although you’ll probably never want to go back to a high-sugar, high-dairy diet!
If you’ve been struggling with your skin for a while and are not seeing improvement, you may like to consider working with a nutritionist or other holistic health practitioner to uncover the root cause of your acne and support you with implementing a targeted treatment plan!
If one-on-one nutritional counseling is not of interest to you, check out the Body Awareness Project‘s online program dedicated to healing your skin. The course includes expert interviews covering topics such as liver function, detoxification, gut health, hormonal imbalances, nutritional deficiencies, epigenetics, stress, herbal medicine, essential oils, clean cosmetics and natural skincare. My interview focuses on hormonal imbalances and dives deeper into my three-pronged approach to healing acne using nutrition and lifestyle approaches. I hope you find those resources helpful!
