What is rosacea?
Rosacea is a chronic skin condition that causes a facial rash, which may include red blotches, telangiectasia (spider veins), pimples or spots, and possibly a burning sensation on the skin of the cheeks, nose, chin and forehead. It is a long-term condition that appears more frequently in middle-aged people and can vary in intensity.
What are the symptoms of rosacea?
Rosacea can manifest as several symptoms, including:
Redness of the face (often giving the appearance of blushing)
Bumps or pimples on the skin
Patches of rough, dry skin
Swelling, particularly around the nose and eyes (a bulbous red nose is a common indicator of severe rosacea)
A burning or stinging sensation
Telangiectasia (spider veins – thin and reddish lines form under the skin because the blood vessels under the skin are enlarged.
Eye problems, including itching, dryness, swelling, light-sensitivity, bloodshot or watery appearance, etc.
Different patients may experience a different selection of symptoms, the most common being the unexplained redness of the face, which often bears a resemblance to acne (although the two are distinct conditions).
Rosacea tends to flare up in cycles, with patients suffering symptoms for a period of weeks or months, before the symptoms disappear for a similar period.
What are the causes of rosacea?
The cause of rosacea is unknown but there are several factors that are thought to contribute to or worsen it. For example excessive consumption of alcohol, caffeine or hot and spicy food is thought to trigger episodes, as can intense physical activity. Other factors include:
Age – rosacea occurs most commonly in people between 30 and 50 years of age.
Skin type – fair-skinned people seem to be more susceptible (especially those with blond hair and blue eyes).
Genetics – family history of the condition means you are more likely to suffer from rosacea. It it also more common in people of Celtic and Scandinavian ancestry.
Hormonal changes (for example, the menopause)
Sudden changes in temperature
Exposure to sun or wind
Stress
Some medications
Certain bacteria like helicobacter pylori

What causes eczema?
Several factors cause eczema, including:
Your immune system: If you have eczema, your immune system overreacts to small irritants or allergens (triggers) in your environment. When you contact a trigger, your immune system assumes that these small irritants are foreign invaders, like bacteria or viruses, that can harm your body. As a result, the triggers activate your body’s natural defense system. Your immune system’s defense is to create inflammation. Inflammation causes symptoms of eczema on your skin.
Your genes: You’re more likely to have eczema if there’s a history of eczema or dermatitis in your family. You’re also at a higher risk if there’s a history of asthma, hay fever and/or allergies. Common allergies include pollen, pet hair or foods that trigger an allergic reaction. You could also have a genetic mutation that causes your skin’s barrier function to not work as it should.
Your environment: There’s a lot in your environment that can irritate your skin. Some examples include exposure to smoke, air pollutants, harsh soaps, fabrics such as wool, and some skin care products. Low humidity (dry air) can cause your skin to become dry and itchy. Heat and high humidity can cause sweating and that can make your itchiness even worse.
Emotional triggers: Your mental health could affect the health of your skin, which can cause a flare-up of eczema symptoms. If you have high levels of stress, anxiety or depression, you may have more frequent flare-ups of eczema symptoms.
What triggers eczema to flare up?
Eczema affects each person diagnosed with the condition differently. What causes your symptoms to flare up might not trigger someone else with the condition. Common triggers that cause eczema include:
Dry weather (low humidity).
Fabrics or clothing material.
Makeup or skin care products.
Smoke and pollutants.
Soaps and detergents.
Stress or your emotional well-being.
Touching something you’re allergic to.

Eczema
Eczema is a skin condition that causes dry and itchy patches of skin. It’s a common condition that isn’t contagious. Symptoms of eczema can flare up if you contact an irritant or an allergen.
What are the types of eczema?
There are several types of eczema. Each type has unique triggers that can affect your skin’s barrier function, including:
Atopic dermatitis.
Contact dermatitis.
Dyshidrotic eczema.
Neurodermatitis.
Nummular eczema.
Seborrheic dermatitis.
It’s possible to have more than one type of eczema at the same time.
Who does eczema affect?
Eczema can affect anyone at any age. Symptoms usually appear during childhood and last into adulthood. You might be more at risk of having eczema if you have a family history or a diagnosis of:
Dermatitis.
Allergies.
Hay fever.
Asthma.
How common is eczema?
Eczema is common and affects more than 31 million Americans. Infants are prone to eczema, and 10% to 20% will have it. However, nearly half of all infants diagnosed with eczema outgrow the condition or have significant improvement as they get older.
What causes eczema to start?
The first signs of eczema are itchiness, dry skin and a rash. These signs indicate that you came into contact with a trigger in your environment that caused your symptoms to start or flare up. Identifying environmental triggers and avoiding them can reduce your risk of an eczema flare-up in your future.
