Skin tone: Discoloration caused by bruises is more prominent in lighter complexions. Diseases: Coagulation, platelet and blood vessel diseases or deficiencies can increase bruising due to more bleeding. Location: More extensive vascularity causes more bleeding. Areas such as the arms, knees, shins and the facial area are especially common ...
The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3]
An ecchymosis is a hematoma of the skin larger than 10 mm. [2] They may occur among and or within many areas such as skin and other organs, connective tissues, bone, joints and muscle. A collection of blood (or even a hemorrhage) may be aggravated by anticoagulant medication (blood thinner).
Long-term steroid use, on the other hand, causes thinning of the skin, making it more susceptible to bruising. That same logic applies to older folks’ tendency to bruise like a peach.
A welt is a bloodshot stripe on the skin. They are hematoma, a special form of a bruise. Welts occur when blunt force is applied to the body with elongated objects without sharp edges. Like other haematomas, welts change their colors as they heal, which usually takes two to four weeks.
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease. [3]
A contusion is the discoloration of the skin, which results from underlying muscle fibers and connective tissue being crushed. This can happen in a variety of ways such as a direct blow to the skin, or a fall taken against a hard surface. The discoloration in the skin is present when blood begins to pool around the injury.
The treatment is the same as that for bruises in other parts of the body – cold compresses during the first twenty-four hours. During the process of healing, and so long as there no breaks in the skin, a black eye can be made less conspicuous by using cosmetics designed to obscure discolorations of the skin.
