FAQ (Frequently Asked Questions)
Do facial bacteria cause rosacea?
No, facial bacteria do not cause rosacea. Detailed analysis of rosacea skin and papules has demonstrated that bacteria are completely normal.
Do facial demodex mites cause rosacea?
No, facial demodex mites do not cause rosacea. Although a few studies have demonstrated increased numbers of demodex on the skin of some rosacea sufferers, most experts agree that they do not play a role in rosacea -- they are just harmless passengers that are found on facial skin.
Is rosacea caused by abnormal sebaceous gland growth or activity?
No, the average rosacea sufferer has normal facial sebaceous glands (both in structure and activity). Numerous clinical studies have demonstrated that true rosacea does not involve the facial sebaceous glands. Please note that there is one exception to this rule -- rosacea sufferers who develop rhinophyma (the bulbous red nose). After years of flushing, rhinophyma sufferers may experience inflammation and growth of the sebaceous glands around the nose.
Is rosacea contagious?
No, rosacea is not contagious. It is important to emphasize that genetics does play a role in the development of rosacea, so rosacea can often be seen in members of the same family and in close relatives.
Does rosacea go away by itself or 'burn itself out'?
Rosacea does not go away by itself or burn itself out. A sufferer may notice that rosacea symptoms may wax and wane over time but, no matter what the stage or symptom severity, the underlying disorder is still present. |
