Vascular Lesions - Rosacea
An inflammation of the skin characterized by extreme redness, dilation of blood vessels, and in severe cases the formation of papules and pustules. It is chronic congestion primarily on the cheeks and nose. The cause and treatment of rosacea is a primary skin care concern. The cause is unknown =, but may be due to heredity, bacteria, mites, or fungus. Certain factors are known to aggravate the condition. Vasodilation of the blood vessels makes rosacea worse. Spicy foods, alcohol, caffeine, temperature extremes, hear, sun, and stress aggravate rosacea.
Vascular Lesions - Telangiectasia
A vascular lesion; describes capillaries that have been damaged and are now larger, or distended blood vessels. Commonly called couperose skin and characterized by redness.
Vascular Lesions - Varicose veins
Vacular lesions that are abnormally dilated and twisted veins which can occur anywhere in the body. Sometimes treated with sclerotherapy, a nonsurgical injection into the vein. Surgery is a treatment option for serious vein problems.
Allergic Contact Dermititis
Allergic contact dermatitis is cased by exposure and direct skin contact to an allergen. Normally the immune system protects us from pathogens and disease, but in an allergic reaction the immune system actually causes the problem by trying to do its job too well. An allergic reaction occurs when our immune systems mistakes a substance for a toxic one and initiates a major defense against it.
Irritant Contact Dermatitis
Irritant reactions affect everyone who comes in contact with an irritant, although the degree of irritation will vary depending on the individual. In acute case, symptoms are noticed immediately or within just a few hours. Chronic cases may be delayed reactions from redness, swelling, scaling, and itching to serious, painful chemical burns. Caustic substances are examples of irritants. When the skin is damaged by irritating substances, the immune system springs into actions. It floods the tissue with water, trying to dilute the irritant. This why swelling occurs.
