Rosacea is a common inflammatory skin condition that affects millions of people worldwide. It is characterised by redness on the face, neck, ears, and back, caused by broken blood vessels, and can result in acne-like bumps and pustules. While the exact cause of rosacea is unknown, certain dietary and environmental factors are known to trigger or worsen symptoms. These include alcohol, spicy food, hot drinks, and histamine-rich foods. As such, an autoimmune diet that eliminates these trigger foods may help to reduce rosacea flare-ups and improve overall skin health. Additionally, a healthy gut biome is believed to improve ocular health and reduce inflammation, which may also help manage rosacea.

What You'll Learn
A healthy gut biome can improve ocular rosacea
Rosacea is a chronic inflammatory skin condition that affects the central face and periocular regions. It is characterised by redness, enlarged pores, red bumps, pimples, and patches of dry, rough skin. It can also cause vision problems. Ocular rosacea symptoms include dryness, burning, itching, photophobia, blurred vision, and foreign body sensation.
Supplements such as omega-3 fatty acids can also aid in decreasing inflammation of the ocular surface and improve oil production from the meibomian glands. A case report illustrated the efficacy of oral antibiotics and probiotics combined therapy in a patient with scalp rosacea. After eight weeks of treatment with 40mg of doxycycline per day and a probiotic mixture, the patient's cutaneous and ocular symptoms significantly improved.
In addition to a healthy gut biome, it is important to practice good lid hygiene, including warm compresses, hypochlorous acid sprays, and artificial tears. Patients should also be advised to wear sunscreen and clothing with built-in sun protection when outdoors to prevent sun damage, which can trigger rosacea flare-ups.

Prebiotics and probiotics can help to reduce inflammation
Rosacea is a chronic inflammatory skin condition characterised by redness, flushing, and skin sensitivity. It is estimated that rosacea affects 15% of certain populations, with higher prevalence in fair-skinned individuals of European descent. The pathogenesis of rosacea is hypothesised to be a combination of immune system dysregulation, abnormal vascular and neurological signalling, and dysbiosis of microorganisms leading to inflammation of the skin.
Certain foods and beverages are known to trigger or worsen rosacea symptoms, and dietary changes may play a role in managing the condition. Triggers include alcohol, spicy food, hot drinks, and cinnamaldehyde-containing foods such as tomatoes, citrus fruits, and chocolate.
Prebiotics and probiotics can help promote a healthy gut biome, which in turn can improve ocular health and reduce inflammation throughout the body, including the skin. Prebiotics are nondigestible foods that act as food for the microflora, and many high-fibre foods act as prebiotics. Probiotics are live microorganisms that maintain or improve our normal microflora and can be taken as supplements.
While there is a recognised link between rosacea and the gut microbiota, there is limited research on the role of the gut-skin axis in rosacea, and insufficient clinical trial evidence to support the efficacy of probiotics in treating rosacea. However, probiotics have been found to have anti-inflammatory effects and may help treat other inflammatory skin conditions. Some individuals with rosacea may find that including probiotics in their diet or taking probiotic supplements improves their symptoms.
Probiotic foods include fermented foods such as yogurt, kefir, miso, kimchi, and sauerkraut, and they can also be taken as supplements. Oral probiotics that may be beneficial for individuals with rosacea include Nitrobacter, Lactobacillus, and Bifidobacterium.

Alcohol, spicy food, and hot drinks are common triggers
Alcohol is a known trigger for rosacea, as it induces peripheral vasodilation, promotes inflammation and oxidative stress, and modulates the immune system. Its breakdown products, acetaldehyde and acetic acid, cause a histamine release that can trigger and exacerbate flushing and edema. Red wine, in particular, is known to be tough on rosacea symptoms. However, the association between alcohol intake and rosacea development and severity is still controversial and debatable.
Spicy foods are also common triggers for rosacea. Capsaicin, an organic compound found in peppers, binds to TRPV1 receptors in the thalamus and sensory neurons, causing vasodilation and a stinging sensation. While a study by Yuan et al. did not show a causal link between spicy food and rosacea, it suggested that spicy food could aggravate symptoms like flushing, stinging, and burning. Curries, chillies, pepper, and hot sauces are some examples of spicy foods that should be avoided or minimised to prevent rosacea flare-ups.
Hot drinks, such as coffee, tea, and other caffeinated beverages, can also trigger rosacea flares. These drinks can cause vasodilation and stimulate the TRPV1 receptor, leading to flushing, stinging, and sensitive skin. However, it is not necessary to completely eliminate hot drinks from your diet. Allowing beverages to cool down to a warm or lukewarm temperature before consuming them can help prevent rosacea symptoms. Alternatively, opting for cold alternatives, such as iced coffee or iced tea, can be a good option.
In addition to avoiding these common triggers, promoting a healthy gut biome is crucial for managing rosacea. This includes incorporating prebiotic and probiotic foods or supplements into the diet. Omega-3 fatty acids, for example, can aid in decreasing inflammation and improving ocular health. Identifying unique triggers through a journal of rosacea flare-ups can also help manage the condition effectively.

Sun exposure is a well-known trigger for rosacea flare-ups
Rosacea is a chronic inflammatory skin condition characterised by redness, enlarged pores, red bumps, pimples, and patches of dry, rough skin. It is most common in fair-skinned people and women in menopause. The cause of rosacea is not yet fully understood, but it is believed to be genetic in some cases.
To avoid rosacea flare-ups, it is recommended that people prone to rosacea protect their skin when outdoors. This includes wearing sunscreen with an SPF of 15 or higher, year-round, and seeking shade whenever possible. Sunscreen should be fragrance-free and contain zinc oxide, titanium dioxide, or both, to minimise skin irritation. Additionally, wearing a wide-brimmed hat and sunglasses can help shield the face from the sun. It is also recommended to avoid peak sunlight hours, typically between 10 am and 4 pm, when the sun is at its strongest.
Other common triggers for rosacea include spicy food, alcohol, hot beverages, and emotional stress. Identifying and avoiding these triggers can help manage rosacea symptoms.

A healthy, balanced diet can help to manage rosacea
Rosacea is a chronic inflammatory skin condition that affects millions of people worldwide. It is characterised by redness on the face, neck, and occasionally the ears and back. While the exact cause of rosacea is unknown, certain dietary and environmental factors are known to trigger or worsen symptoms. These include alcohol, spicy food, heat, sunlight exposure, and certain food groups.
In addition to prebiotics and probiotics, omega-3 fatty acids are also beneficial for rosacea. Omega-3 supplements can aid in decreasing inflammation of the ocular surface and improving oil production from the meibomian glands. It is important to note that dietary changes may not work for all patients, and further studies are needed to fully understand the link between diet and rosacea subtypes. However, keeping a journal of rosacea flare-ups and identifying unique triggers can help individuals manage their symptoms effectively.
To summarise, a healthy, balanced diet that includes prebiotic and probiotic foods, as well as omega-3 fatty acids, can help manage rosacea by promoting a healthy gut biome and reducing inflammation. Additionally, avoiding known dietary triggers such as alcohol, spicy food, and heat can further help in managing rosacea symptoms.
