Foods That Trigger Perioral Dermatitis: What to Avoid & Eat

Perioral dermatitis (PD) is a skin condition marked by red, bumpy rashes that can cause discomfort and affect daily life. No exact cause has yet been found, although several factors can lead to it, including genetics, hormones, and even some medications.


According to a 2024 study on Dietary Influences on Skin Health in Common Dermatological Disorders, diet may also have an impact on symptom management. Let's get to know what to avoid and what to eat for the effective management of perioral dermatitis.

What Is Perioral Dermatitis?

Perioral dermatitis (PD) is a common skin condition that normally manifests as a bumpy, red rash around the mouth. This condition can affect the skin around the nose, eyes, and, in rare cases, the genitals. Rising perioral dermatitis may look similar to acne or rosacea, bringing a mistaken diagnosis.

Causes of Perioral Dermatitis


While the cause is unclear, several factors may be involved:

  • Topical Steroid Use: Long-term use of topical steroids, especially on the face, can cause rebound inflammation leading to perioral dermatitis.

  • Hormonal Changes: Hormonal fluctuations, especially in women, often trigger the condition.

  • Skin Irritants: These include skin care products, such as harsh cleansers or moisturizers, which can irritate perioral dermatitis.

  • Dietary Factors: Some people may find that certain foods such as milk or spicy foods, can worsen their skin.

Foods That Trigger Perioral Dermatitis

Identifying food triggers and avoiding them plays an important part in managing perioral dermatitis. Some common offenders include the following:

Spicy Foods

An ingredient such as chili pepper will increase the sensitivity of the skin and cause redness or even irritation. Therefore, to avoid flare-ups, avoid heavily spiced meals.

Citrus Fruits

Citrus fruits' high acidity and similar protein structures to plants can cause cross-reactivity, causing allergic reactions when the immune system mistakenly identifies them as allergens, according to a National Library of Medicine study.

Tomatoes

Similar to citrus fruits, the acidity in tomatoes might trigger inflammation around the mouth. You should stay away from raw tomatoes, sauces, and ketchup.

Chocolate

Some people find that chocolate, especially chocolate varieties high in sugar and with high dairy content, may cause flare-ups. Therefore, dark chocolate with restricted intake might be a better alternative.

Caffeine

Excessive caffeine intake can lead to dehydration and cause inflammation throughout the body. Thus, it can impair skin health. Herbal teas are soothing alternatives that calm inflammation and are good for your skin.

Chewing Gums

Artificial sweeteners and additives in some chewing gum are potential triggers. Therefore, you should check ingredient labels for aspartame or sorbitol before eating any gum.

Inflammatory Foods to Avoid

To manage perioral dermatitis, reducing inflammation is key. Here are the inflammatory foods that are commonly advised to be eliminated:

Sugar and Artificial Sweeteners

Refined sugars or sweeteners increase insulin levels and, therefore, aid inflammation. Switch to natural replacement foods such as raw honey or stevia.

Trans Fats

Found in fried foods and processed baked goods, trans fats promote inflammation in the body. You should always check on the label "partially hydrogenated oils" to avoid any flare-ups.

Refined Grains

White bread, pasta, and other refined grains lack nutrients. These foods can raise blood sugar and contribute to blood sugar spikes. Therefore, you should opt for whole-grain versions instead.

Dairy Products

Dairy, such as cheese, milk, and other products, may aggravate symptoms. Hormones present in cow’s milk, particularly prostaglandins (PGs), can increase inflammation. According to a National Library of Medicine study, high levels of PGs like PGE2, found in milk, are bioactive lipids that may contribute to inflammatory processes in the body. You should change to plant-based options to see if it makes any difference to your skin.

Processed Meats

Processed meats, such as bacon, sausages, and deli meats, are laden with sodium, nitrates, saturated fats, and preservatives, all of which can fuel inflammation within the body. This chronic inflammation can negatively impact skin health. Research published in the Journal of Investigative Dermatology has demonstrated that advanced glycosylation end-products (AGEs), abundant in processed meats, can stimulate inflammation and oxidative stress, accelerating skin aging. You can eat chicken, fish, or lean protein, which can reduce reactions.

Alcohol

Excessive consumption of alcohol can also upset your gut and dehydrate your skin, as well as impair the body’s natural healing process. You need to restrict your intake of alcohol or drink non-alcoholic beverages instead.

Diet for Managing Perioral Dermatitis

Adopting an anti-inflammatory diet can significantly benefit skin health. Nutrient-dense foods should be included to support healing and reduce inflammation:

  • Fatty Fish: Salmon, tuna, and mackerel are the best sources of omega-3 fatty acids, which are known for their anti-inflammatory properties. This study in Dermatologic Therapy has discussed the role of omega-3 fatty acids in reducing inflammation and improving skin conditions, including dermatitis.

  • Leafy Greens: Kale, spinach, and various green vegetables are loaded with nutrients and support skin health.

  • Fruits: Fruits rich in antioxidants and vitamins, such as berries (including blueberries, raspberries, and strawberries), apples, and pears, are beneficial for skin health. A review published in Innovative Food Science & Emerging Technologies highlights that antioxidants in fruits can mitigate oxidative stress and inflammation in the skin.

  • Greek Yogurt: A good source of probiotics, greek yogurt can support gut health, which may positively impact the skin.

  • Broccoli: These cruciferous vegetables are rich in antioxidants, and sulforaphane may have anti-inflammatory effects.

  • Whole Grains: Brown rice, quinoa, and oats provide sustained energy and promote gut health.

  • Plant Milk: Almond milk, coconut milk, and other plant-based alternatives are also sources of calcium and other nutrients available without dairy. A Journal of the American Academy of Dermatology research supports the statement that dairy alternatives are beneficial for individuals with skin conditions like perioral dermatitis.

  • Avocado: This healthy fat source is rich in vitamins and antioxidants that nourish the skin.

  • Probiotic-Rich Foods: Kefir, sauerkraut, and kimchi have healthy bacteria promoting gut health, potentially impacting skin health.

  • Bone Broth: This healthy broth will nourish the gut and may be beneficial for overall health. A review published in the Journal of Medicinal Food discussed the potential benefits of bone broth for gut health and overall health.

  • Turmeric: This golden spice has powerful anti-inflammatory properties. A study published in the Journal of Medicinal Food found that curcumin, a compound in turmeric, has potent anti-inflammatory effects and may be beneficial for reducing inflammation in the skin.

  • Mung Bean Sprouts: The vitamins and antioxidants in mung bean sprouts help maintain healthy skin.

  • Raw Honey: Sugar should be consumed in moderation, but raw honey offers some health benefits and can be used sparingly.

Additional Tips for Improving Perioral Dermatitis

Diet is just one piece of the puzzle. Incorporate these lifestyle habits for better results:

  • Stay Hydrated: Drinking at least 8 glasses of water flushes body toxins and hydrates the skin.

  • Limit Processed Foods: Most processed foods have various inflammatory agents. You should change to whole and unprocessed foods whenever possible.

  • Manage Your Stress: Stress is a known trigger for perioral dermatitis. Consider incorporating stress-reduction techniques like yoga or meditation into your routine. Supplements like Phoilex’s Liverty Dynamic Drops may also help manage stress effectively. You can use this product to act as a stress reliever as effectively as taking part in other activities.

  • Must-Have Natural Product for Treating Perioral Dermatitis: Consider using the Active ReLeaf Spot Gel for targeted skincare solutions. This product is designed to calm and heal irritated skin, also providing relief from perioral dermatitis.

Key Takeaway

While perioral dermatitis can be frustrating, dietary changes can play a significant role in managing symptoms. Avoiding foods that trigger symptoms and adding anti-inflammatory, nutritious options can help improve your skin and reduce flare-ups. A good skincare routine and healthy habits also play an important role.
