What is Rosacea?

Rosacea is a chronic medical condition of the face characterized by erythema (redness). Pimples may also sometimes appear. The neck and upper chest may also be affected. Rosacea is usually a harmless cosmetic condition affecting middle aged and older people. It can however become serious if the eyes are affected.

Causes of Rosacea

  • No one single factor is responsible for the onset of Rosacea. It is caused by a combination of genetic disposition and environmental factors.
  • A few researches have established a link between mites that survive in facial hair follicles and development of Rosacea.
  • A bacterium named Helicobacter pylori which reside underneath the mucus layer near the stomach and causes peptic ulcers and gastritis has also been linked with Rosacea.
  • Various triggers that cause flushing episodes may play a part in Rosacea‚Äôs development.
  • Exposure to extreme temperatures
  • Severe sunburn
  • Heat from sunlight
  • Stress and anxiety
  • Cold wind
  • Certain food and beverages such as those containing alcohol, caffeine. Foods containing high levels of histamines such as aged cheeses, cured pork products, yoghurt
  • A few medications and topical irritants such as wrinkle and acne treatments can trigger off Rosacea. Chemical peels, microdermabrasion, isotretinoin, tretinoin, benzoyl peroxide can also cause Rosacea. The use of nasal and topical steroids can also induce Rosacea if they are stopped abruptly.

Diagnosis of Rosacea

Diagnosis for Rosacea is made clinically. Acne is commonly confused with Rosacea but can be distinguished by age, presence of comedones and absence of flushing.

Medication for Rosacea

Dermatologists may prescribe topical antibiotics like metronidazole gel or cream, clindamycin solution, lotion or gel for 5-8 weeks for a significant response. In case topical treatments fail, oral antibiotics may be prescribed. The common anti bitocs given for Rosacea include tetracycline, erythromycin, doxycycline and minocycline. Isotretinoine can be prescribed for severe cases of Rosacea but because it causes adverse side effects, pregnant women should avoid this.

Surgery for Rosacea

Laser surgery and electrosurgery can be used to treat rhinophyma and redness. A yellow light laser can be used to treat skin lesions.

  • Phymatous Rosacea is commonly associated with rhinophyma (swelling or enlargement of the nose with thick knobby bumps). The symptoms for this include thickened skin and a few irregular surface enlarged nodulrd. This kind of rosacea can also affect the forehead, chin, cheeks, ears and eyelids.
