The skin on the face becomes red, and some have an increased tendency to blush. In others, there may be more permanent redness, which may be due to more small blood vessels forming at the outermost part of the skin. There are small pus-filled pimples, and there may be small knots and unevenness in the skin. In a few, the problems on the eyelids may be the most pronounced. Some people experience swelling of the skin. It doesn't itch a bit, but it can sting and burn a little.
This is an inflammation that occurs in the skin's blood vessels, sebaceous glands and hair follicles. The skin's own immune system is activated, but exactly what triggers rosacea is unclear. People with light skin find it easier. It typically occurs after the age of 30. Some theories suggest that there is an increased presence of mites in the skin or that sunlight over several years can trigger this.
Most people are helped by gel or cream, some of which can be bought at pharmacies without a prescription. Quite a few need a period of antibiotic tablets. Those who have a lot of redness in the skin may benefit from a gel that reduces this, or may benefit from laser treatment carried out by a dermatologist.
