Polycystic ovary syndrome (PCOS) is a common hormonal disorder that affects women of reproductive age. It is characterized by hormonal imbalances and metabolic disruption, affecting 5-10% of females aged 15-44. PCOS can manifest in various ways, including ovarian cysts, reduced or absent menstruation, and elevated androgen hormones. These hormonal imbalances can lead to a range of symptoms, including acne. While there is no cure for PCOS, dietary and lifestyle modifications, along with medical treatment, can help manage symptoms and improve overall well-being.
The Link Between PCOS and Acne
Acne is a common and often distressing symptom of PCOS. It is primarily related to high levels of androgens, such as testosterone and dihydrotestosterone (DHT). These hormones, present in all women, stimulate the sebaceous glands to produce excessive oil, which can clog pores and lead to acne breakouts. This type of acne is often located on the jawline, chin, and cheeks, and tends to be cystic, meaning the breakouts are deep, inflamed, and painful.
Acne associated with PCOS can persist well beyond adolescence, sometimes extending past menopause. It can affect not only the face but also other areas of the body, such as the back, chest, inner thighs, and underarm areas. In some cases, individuals with PCOS may develop hidradenitis suppurativa (HS), characterized by boils or unsightly bumps on the skin, particularly in areas that experience friction, such as the underarms and inner thighs.
The Role of Diet in Managing PCOS and Acne
While diet is not a direct cause of acne in PCOS, certain dietary choices can significantly impact hormone levels, insulin resistance, and inflammation, all of which play a role in acne development. A well-balanced diet can help manage these factors and potentially reduce acne breakouts.
General Dietary Recommendations for PCOS
There is no one-size-fits-all diet for PCOS, but several strategies can be beneficial. A healthy diet for PCOS generally focuses on whole, natural foods that provide sustained energy without causing drastic spikes in blood sugar or exacerbating hormonal imbalances.

“Health optimization in people with PCOS is sensitive to a lot of things - especially the things we eat and drink, our sleep-wake cycle, and physical activity,”. “Start with a balanced diet of whole, fresh foods as much as possible and limit ultra-processed foods. And put that diet into context of your circadian rhythms (your sleep-wake cycle). This approach will help you control your blood glucose, which affects insulin and androgen levels.
Here are some key dietary approaches that may help manage PCOS symptoms, including acne:
Low Glycemic Index (GI) Diet: This diet emphasizes foods that are digested slowly, causing a gradual rise in blood sugar levels. This helps prevent insulin spikes, which can worsen insulin resistance and androgen production. Examples of low GI foods include whole grains, legumes, nuts, seeds, fruits, and starchy vegetables.
Anti-Inflammatory Diet: Inflammation can exacerbate PCOS symptoms, including acne. An anti-inflammatory diet focuses on foods that reduce inflammation in the body. These include berries, oily fish, leafy greens, and extra virgin olive oil.
DASH Diet: The Dietary Approaches to Stop Hypertension (DASH) diet is rich in fish, poultry, fruits, vegetables, whole grains, and low-fat dairy products. It is low in saturated fats, cholesterol, refined grains, and sweets. The DASH diet may improve various features of PCOS, including the appearance of ovaries, insulin resistance, glucose management, and fat deposits.

Foods to Include in a PCOS-Friendly Diet
A PCOS-friendly diet should include a variety of nutrient-dense foods that support hormone balance, reduce inflammation, and promote overall health. Some specific foods to incorporate are:
- High-Fiber Foods: Fiber helps stabilize blood sugar levels and improve insulin sensitivity. Good sources of fiber include whole grains, legumes, vegetables, and fruits. Examples include oats, brown rice, quinoa, lentils, and beans.
- Lean Protein: Protein is essential for satiety and muscle maintenance. Choose lean protein sources such as chicken, turkey, fish, tofu, and low-fat dairy products.
- Healthy Fats: Unsaturated fats can help reduce inflammation and balance hormones. Include sources like avocados, nuts, seeds, fatty fish (salmon, tuna, sardines), and olive oil.
- Non-Starchy Fruits and Vegetables: These provide essential vitamins, minerals, and antioxidants without causing significant blood sugar spikes. Opt for berries, citrus fruits, melon, broccoli, celery, leafy greens, peppers, and mushrooms.
- Antioxidant-Rich Foods: Antioxidants help combat oxidative stress and inflammation. Include berries, dark leafy greens, nuts, seeds, and green tea in your diet. Specific antioxidants like Alpha Lipoic Acid (ALA), vitamin C, and vitamin E have been shown to reduce some symptoms of PCOS by regulating lipid and glucose metabolism.
- Gut-Healthy Foods: Gut health is linked to PCOS. Prebiotic and probiotic foods can be beneficial. Prebiotic foods, such as bananas, artichokes, asparagus, and apples, contain dietary fiber that feeds the “good” bacteria in your stomach. Probiotic foods, such as sauerkraut, kimchi, yogurt, and kefir, contain live bacteria to supplement the gut microbiome.
- Zinc-Rich Foods: Low levels of zinc have been found in women with PCOS. Zinc works to inhibit the enzyme that converts testosterone into its non-aromatizable form, dihydrotestosterone (DHT), which contributes to acne.
Foods to Limit or Avoid
Certain foods can exacerbate PCOS symptoms and potentially worsen acne. It's best to limit or avoid the following:
- Refined Carbohydrates: These include white bread, white rice, pastries, and sugary cereals. They cause rapid spikes in blood sugar and insulin levels.
- Sugary Foods and Beverages: Limit your intake of soda, fruit juice, candy, and processed sweets. These can contribute to insulin resistance and inflammation.
- Fried Foods: Fried foods are often high in unhealthy fats and can contribute to inflammation.
- Processed Foods: These foods are typically high in salt, sugar, and unhealthy fats, and low in nutrients. Examples include packaged snacks, processed meats, and fast food.
- Dairy (Potentially): Some women with PCOS find that dairy products worsen their acne. Non-fat milk can increase androgen and insulin levels. Experiment with eliminating dairy for a few weeks to see if your skin improves. If you do consume dairy, opt for full-fat products or fermented options like yogurt and kefir.
Specific Nutrients and Supplements
In addition to dietary changes, certain nutrients and supplements may be helpful for managing PCOS and acne:
- Inositol: This naturally occurring sugar has shown promise in improving insulin sensitivity, egg quality, and ovulation. Studies suggest that inositol can also reduce acne and lower androgen levels in women with PCOS.
- Zinc: This trace mineral is essential for hormone regulation and skin health. Supplementing with zinc may help reduce acne by inhibiting the conversion of testosterone to DHT.
- Omega-3 Fatty Acids: These healthy fats have anti-inflammatory properties and may help reduce acne. Include sources like fatty fish, flaxseeds, and chia seeds in your diet.
Sample Meal Plan
To help you visualize a PCOS-friendly diet, here's a sample meal plan:
- Breakfast: Oatmeal with berries and nuts, or Greek yogurt with fruit and seeds.
- Lunch: Salad with grilled chicken or fish, or a lentil soup with whole-grain bread.
- Dinner: Baked salmon with roasted vegetables, or a stir-fry with tofu and brown rice.
- Snacks: A handful of nuts, a piece of fruit, or a small portion of Greek yogurt.
Additional Lifestyle Factors
In addition to diet, other lifestyle factors can significantly impact PCOS and acne:

- Exercise: Regular physical activity can improve insulin sensitivity, promote weight loss, and reduce inflammation. Aim for at least 150 minutes of cardio exercise per week, along with strength training.
- Sleep: Getting enough sleep is crucial for hormone regulation and overall health. Aim for 7-8 hours of quality sleep per night.
- Stress Management: Chronic stress can worsen PCOS symptoms. Practice stress-reducing activities like yoga, meditation, or spending time in nature.
- Skin Care Routine: Follow a consistent skin care routine to keep your skin clean and healthy. Change your pillowcase regularly to prevent bacteria buildup.
Medical Treatments
While diet and lifestyle changes can be very effective in managing PCOS and acne, medical treatments may also be necessary. Your doctor may prescribe:
- Contraceptive Medications: Birth control pills can help regulate hormone levels and reduce acne.
- Spironolactone: This medication can block the effects of androgens and reduce acne.
- Diabetes Medications: If you have insulin resistance, your doctor may prescribe medications like metformin to improve insulin sensitivity.
- Topical Creams or Antibiotics: These can help treat acne but often with limited success.
