Definitions of Primary Conditions:
Rosacea - a chronic inflammatory disorder involving especially the skin and vasculature of the nose, forehead, and cheeks; characterized by congestion, flushing, telangiectasia, and marked nodular swelling of tissues especially of the nose.
Erythema of Rosacea - inflammatory redness of the skin; develops gradually as mild episodes of facial blushing or flushing which, over time, may lead to a permanently red face.
Telangiectasia - small dilated or broken segments of a blood vessel visible through the epidermis, including small terminal segments or clustered patterns known as "spider telangiectasia"; may occur as the result of skin aging and/or solar or
environmental effects.
Hyperpigmentation - common, usually harmless condition in which patches of skin become darker in color than the surrounding skin; often occurs in patches of sun induced freckles.
Melasma - form of diffuse, symmetrical hyperpigmentation on the face that appears most often as a result of hormonal changes, such as during pregnancy or from birth control pills.
Poikiloderma - a variegated hyperpigmentation and telangiectasia of the skin followed by atrophy.
Age Spots - small round dark macules (frequently sun related), freckles, and hyperpigmented patches; may occur as the result of skin aging and/or solar or environmental effects; may be of varied severity, and may involve the face as well as non-facial areas.
