Rosacea is a common skin condition that causes blushing or flushing and visible blood vessels in your face. It may also produce small, pus-filled bumps. These signs and symptoms may flare up for weeks to months and then go away for a while.
The cause of rosacea is unknown but is closely linked to :
Overactive immune system
Genetics
Environmental factors
Or often a combination of all three.
Treatments are generally needed when a flare up occurs.
2 - 3 treatments are advised to produce effective lasting results, some bruising and swelling can occur after treatment but does reduce quickly.
