Rosacea requires a medical diagnosis. Please don't believe you may have this condition (which is lifelong) without securing a diagnosis.

Modern zinc oxide sunscreens aren't as protective as many believe. Zinc is only completely protective against UV in opaque form. Lighter and clear forms allow light to pass through. You must use this type of zinc in combination with another block for acceptable protection.

If your sunscreen is older than six months old, throw it out – keep your bathroom stocked with sunscreen you actually like to use. For patients with rosacea a non-irritating, anti-inflammatory and pleasant-to-use sunscreen is critical.

There have been many requests for specific rosacea sunscreens I recommend, so I have made a list of my suggestions at ... These are sunscreens patients seem to do particularly well with and are a good place to start given the 100s from which patients can choose. I particularly like the new La Prairie sunscreen and Rosacea Treatment Clinic sunscreens in general, particularly the new SPF 30 and SPF 50 which contain the latest sunscreen agents – more effective than what's available in the US and with cosmetic properties belying the fact that they are sunscreens.

Bacterial Cause Found For Skin Condition Rosacea

Scientists are closer to establishing a definitive bacterial cause for the skin condition rosacea. This will allow more targeted, effective treatments to be developed for sufferers, according to a review published in the Journal of Medical Microbiology.

Rosacea is a common dermatological condition that causes reddening and inflammation of the skin mostly around the cheeks, nose and chin. In severe cases skin lesions may form and lead to disfigurement. Rosacea affects around 3% of the population – usually fair-skinned females aged 30-50 and particularly those with weak immune systems. The condition is treated with a variety of antibiotics, even though there has never been a well-established bacterial cause.

A new review carried out by the National University of Ireland concludes that rosacea may be triggered by bacteria that live within tiny mites that reside in the skin.

The mite species Demodex folliculorum is worm-like in shape and usually lives harmlessly inside the pilosebaceous unit which surrounds hair follicles of the face. They are normal inhabitants of the face and increase in number with age and skin damage – for example, following exposure to sunlight. The numbers of Demodex mites living in the skin of rosacea patients is higher than in normal individuals, which has previously suggested a possible role for the mites in initiating the condition.

More recently, the bacterium Bacillus oleronius was isolated from inside a Demodex mite and was found to produce molecules provoking an immune reaction in rosacea patients. Other studies have shown patients with varying types of rosacea react to the molecules produced by this bacterium – exposing it as a likely trigger for the condition. What's more, this bacterium is sensitive to the antibiotics used to treat rosacea.

Dr Kevin Kavanagh who conducted the review explained, "The bacteria live in the digestive tracts of Demodex mites found on the face, in a mutually beneficial relationship. When the mites die, the bacteria are released and leak into surrounding skin tissues - triggering tissue degradation and inflammation."

"Once the numbers of mites increase, so does the number of bacteria, making rosacea more likely to occur. Targeting these bacteria may be a useful way of treating and preventing this condition," said Dr Kavanagh. "Alternatively we could look at controlling the population of Demodex mites in the face. Some pharmaceutical companies are already developing therapies to do this, which represents a novel way of preventing and reversing rosacea, which can be painful and embarrassing for many people."
