Rosacea is a chronic skin condition that causes redness, bumps, and visible blood vessels on the face. While the exact cause of rosacea remains unknown, researchers have identified several factors that can trigger flare-ups.
While rosacea can be a frustrating and persistent condition, it’s important to remember that it’s manageable. By understanding your triggers, following a consistent skincare routine, and seeking professional guidance from a dermatologist, you can significantly improve your skin’s appearance and reduce flare-ups.
Understanding your unique triggers can be a powerful tool in keeping your rosacea under control. Keep reading to learn 10 hidden rosacea triggers you might not have considered!
1. Hidden Sugars and Refined Carbohydrates
While spicy food often takes the spotlight as a rosacea trigger, sugary drinks and refined carbohydrates can also be culprits. These foods can cause blood sugar spikes, leading to inflammation throughout the body, including the skin.
Opting for whole grains, fruits, and vegetables provides sustained energy without the blood sugar crash.
2. Dairy Products

For some individuals with rosacea, dairy products like milk, cheese, and yogurt can trigger flushing and redness. This may be due to a sensitivity to lactose, a natural sugar found in milk, or to specific proteins in dairy.
If you suspect dairy is a trigger, consider eliminating it from your diet for a few weeks and observe any changes in your skin.
3. Certain Medications
Some medications, including vasodilators (which widen blood vessels) and corticosteroids (often used for topical inflammation), can worsen rosacea symptoms. If you take any medications and experience rosacea flare-ups, discuss alternative options with your doctor.
They can help you find medications that effectively address your health concerns without triggering rosacea.
“Rosacea flare-ups can be triggered by vasodilator drugs, such as beta blockers and niacin (vitamin B3), due to their ability to dilate blood vessels and increase blood flow to the face,” said Renee Lucero, DO, from Golden State Dermatology in Carmel. “Additionally, topical fluorinated steroids may exacerbate symptoms in susceptible individuals, though brief use of mild, non-fluorinated steroids or hydrocortisone may be acceptable for those with overlapping rosacea and seborrheic dermatitis.”
4. Hot Showers and Saunas
Hot water and extreme temperatures can dilate blood vessels and increase facial flushing. Enjoying warm showers instead of hot ones and limiting time spent in saunas can help minimize rosacea flare-ups.
Noelle Wands, PA-C at Golden State Dermatology in Carmel adds:
“It’s more than just the temperature of your shower or the weather that can trigger Rosacea when it comes to heat. Heat from cooking over a hot stove, proximity to a campfire, or even drinking hot beverages can contribute to flares. These are aspects of daily life that we can overlook very easily.”
5. Rosacea-Specific Skincare Ingredients
While a gentle skincare routine is essential for rosacea management, some ingredients commonly found in rosacea products can be irritating.
Fragrances, alcohol, and harsh exfoliants can all contribute to redness and inflammation. Your doctor can recommend fragrance-free, gentle skincare products specifically formulated for rosacea-prone skin.
6. Indoor Air Quality
Dry air, common during winter months or in homes with central heating, can exacerbate rosacea symptoms. Using a humidifier can add moisture to the air and help keep your skin feeling comfortable.
Dust mites and other allergens can trigger rosacea flare-ups. Regularly cleaning and vacuuming your home, especially your bedroom, can reduce allergen exposure.
7. Certain Types of Exercise

Exercise is crucial for overall health, but strenuous activity can trigger rosacea flare-ups in some individuals. This is because exercise raises body temperature and increases blood flow to the face.
Opting for lower-intensity workouts or exercising in cooler temperatures can help minimize the risk of a flare-up.
8. Eye Strain and Digital Devices
Spending too much time staring at screens from computers, phones, and tablets can contribute to eye strain and fatigue. This can lead to facial flushing and exacerbate ocular rosacea symptoms.
Taking regular breaks from screens and practicing good posture can help reduce eye strain. Using blue light filter glasses may be beneficial.
9. Internal Temperature Fluctuations
Certain activities, like consuming hot beverages or spicy foods, can cause a temporary rise in internal body temperature. This increase in core temperature can trigger facial flushing and worsen rosacea symptoms. Opting for lukewarm beverages and milder foods can help minimize temperature spikes.
10. Stress and Emotional Upset
Emotional stress is a well-known trigger for rosacea flare-ups. When stressed, the body releases hormones that can cause inflammation and worsen rosacea symptoms.
Techniques like meditation, yoga, and deep breathing exercises can help manage stress and potentially reduce the frequency of rosacea flare-ups. These triggers can worsen symptoms or even bring on a new episode altogether.
Does Genetics Play a Role in Rosacea?
While environmental factors and lifestyle choices play a significant role in triggering rosacea flare-ups, genetics can also contribute to its development. Studies have shown that rosacea tends to run in families, suggesting a genetic predisposition.
If you have a family history of rosacea, you may be more likely to develop the condition yourself. However, it’s important to note that not everyone with a family history will develop rosacea.
Understanding your family history and genetic predisposition can help you take proactive steps to manage your rosacea and minimize flare-ups.
Does Gut Health Impact Rosacea?
Emerging research suggests a connection between gut health and skin conditions like rosacea. The gut microbiome, the collection of bacteria and other microorganisms in your digestive tract, plays a crucial role in overall health and immune function.
An imbalance in the gut microbiome, known as dysbiosis, may contribute to inflammation and trigger rosacea flare-ups. Certain dietary changes and the use of probiotics may help improve gut health and potentially reduce rosacea symptoms. However, more research is needed to fully understand the link between gut health and rosacea.
How Does Sun Exposure Affect Rosacea?
Sun exposure can exacerbate rosacea symptoms, leading to redness, flushing, and increased sensitivity. It’s essential to protect your skin from the sun’s harmful rays, especially if you have rosacea.
“When choosing a sunscreen, look for products labeled ‘broad-spectrum’ and ‘non-comedogenic.’ These sunscreens offer protection against both UVA and UVB rays and are less likely to clog pores.,” said Noelle Wands, PA-C. “For optimal protection, I recommend applying sunscreen every morning and reapplying throughout the day, especially after swimming or excessive sweating.”
Your GSD provider can recommend specific sunscreen products that are well-tolerated by individuals with rosacea. Remember, identifying and avoiding your personal triggers is key to managing rosacea.
