An itchy, swollen lesion caused by a blow, insect bite, skin allergy. Also known as hives and mosquito bites.
A disorder where clients purposely scrape off acne lesions, causing scarring and discoloration.
A thick scar resulting from excess growth of fibrous tissue (collagen). Genetically predisposed.
An open lesion on the skin's mucous membrane of the body, accompanied by pus and loss of skin depth.
Propionibacterium Acne (p. acnes)
Skin disorder characterized by chronic inflammation of the sebaceous glands from retained secretions.
Dry, scaly skin from sebum deficiency can be due to aging, body disorders, alkalies of harsh soaps, or cold.
Benign lesions frequently seen in the oilier areas of the face. Over-growths of the sebaceous glands appear similar to open comedones - doughnut shaped.
A skin condition caused by an inflammation of the sebaceous glands. Inflammation, dry or oily scaling or crusting, and/or itchiness.
Prickly heat; acute inflammatory disorder of the sweat glands. Red vesicles and burning, itching skin from excess heat exposure
mainly affects oily areas. Avoid contact and skin care treatments if a client has eczema.
Hair grows under the surface, instead of growing up and out of the follicle, causing a bacterial infection.
A skin disease characterized by red patches covered with white silver scales. Is not contagious, but can spread by irritating the affected area.
Inflammation of the skin characterized by redness, dilation of blood vessels, and in severe cases the formation of papules and pustules. Chronic congestion primarily on the cheeks and nose. Vasodilation of the blood vessels makes it worse.
Vascular lesions - capillaries that have been damaged and are now larger or distended blood vessels. commonly called Couperose skin.
