Rosacea is a chronic skin disorder characterized by red inflamed patches of skin on the forehead, nose, cheeks, chin, and eyelids. It is usually a harmless condition as long as it does not affect the eyes. Rosacea generally affects facial skin but it can also affect the neck, ears, chest, and scalp. There are four different subtypes of rosacea:

  • Erythematotelangiectatic Rosacea: This subtype causes permanent redness on the skin. The individual may also experience the appearance of small blood vessels on the skin surface with or without accompanying itching sensations.
  • Papulopustular Rosacea: It is characterized by some degree of permanent redness along with the appearance of pustules. This condition is very often confused with acne.
  • Phymatous Rosacea: This subtype usually causes an enlargement of the nose, thickening of the skin and irregular nodularities on the surface of the skin.
  • Ocular Rosacea: This condition affects the eyes and eyelids causing dryness, redness, and irritation inside the eye and on the eyelids.
