The mechanisms behind what triggers the development of rosacea are still poorly understood, however an unfavorable inflammatory immune response to the demodex mite (normally present in our skin) is considered to play a key role.
However, when rosacea is first present in the skin certain triggers can worsen the symptoms.
Specific triggers (see below) can lead to rosacea flushing, which is a transitory intensification of the redness, due to dilation of the tiny vessels in the skin, with a simultaneous burning and stinging sensation.
An episode of flushing can last from minutes to hours, be painful and leave the skin sore.
I’ve divided potential triggers into external and internal triggers.
What triggers flushing is different to each individual. And identifying them can be a lifelong quest.
Sun exposure (UV light)
Certain skincare ingredients Friction on the skin (cleansing, applying products)
Season changes (especially summer/winter)
Heat, cold, wind
Emotional stress (excitement, discomfort)
What are your triggers and how do you manage your flushings?
