It’s not the same as acne, but like acne it can make you feel embarrassed or lose confidence, particularly if it is left untreated.

Rosacea isn’t contagious but there is some evidence that it may be hereditary. There’s no cure for rosacea, but there are treatments available that can help control it.

Rosacea symptoms

You may have rosacea if you have:

• frequent blushing, flushing or redness on your cheek, nose, chin or forehead
• persistent redness that looks similar to a sunburn that does not go away
• small visible blood vessels on your face
• bumps or pimples on your face that might sting or burn
• red or irritated eyes or swollen eyelids.

Over time, the redness may become more persistent.

You may also notice that your skin becomes thicker, especially around your nose, and your nose may become swollen.

In some people rosacea can affect the eyes. This can cause red, sore or gritty eyes or eye margins, which can lead to conjunctivitis and swollen eyelids. See an eye specialist if your eyes are being affected, so treatment can be given to prevent damage.

Rosacea triggers

Many people with rosacea find that certain factors can trigger their symptoms, such as sun exposure, stress, hot weather, alcohol, hot, spicy foods, exercise, hot baths, or certain medications or skin care products.

You may try keeping a diary to help identify what triggers your symptoms. Then you’ll know what to try to avoid.

Rosacea treatments

While there’s no cure for rosacea, there are several treatments your doctor or skin specialist (dermatologist) may recommend to help control the symptoms.

Common treatments include creams or gels containing antibiotics or azelaic acid to put on your skin, and antibiotic pills. Laser treatment may be suggested to treat redness or visible blood vessels.

If you have eye symptoms, you may need to see an eye specialist (ophthalmologist).

Surgery or laser therapy may be recommended if you’ve developed a swollen nose.

Your doctor will probably suggest that you use non-irritating skin-care products, wash your face gently and use sunscreen with an SPF of 15 or more to minimise skin irritation.
