Every person is host to a natural mix of bacteria, fungi and viruses — they are normal inhabitants of the skin, known as the skin microbiome. But the makeup of that community may be very different in those with rosacea, according to the results of a recent NRS-funded study comparing the bacteria found on the faces of rosacea patients and people without the condition.
A poster presented at a recent meeting of the American Academy of Dermatology by Dr. Ronald Marks, professor emeritus at the University of Wales, raised the question of whether subtype 1 (erythematotelangiectatic) rosacea can be distinguished from sun-damaged skin.
Dr. Marks observed that patients with sun-damaged skin often exhibit facial redness and visible blood vessels, which are also symptomatic of subtype 1 rosacea.
The greater warmth of the facial skin of rosacea sufferers may play a role in triggering the unsightly bumps and pimples that are common signs of this disorder, according to a new study funded by a grant from the National Rosacea Society and reported at the recent annual meeting of the Society for Investigative Dermatology.
Many rosacea sufferers grow up with a complexion that initially is very fine. But when rosacea strikes, being accustomed to compliments on a "peaches and cream" complexion can make the relentless march of unsightly redness, pimples and excess tissue growth especially shocking.
