Can You Tell How Old This Bruise Is Based on its Color?
Bruising is one of the most common types of soft tissue injury noted on victims of violence, including those suffering intimate partner violence, sexual assault, child abuse, and vulnerable adult abuse. Unidentified injuries can lead to a disparity in the forensic investigation of certain victims, particularly those who have darker skin color or delay seeking treatment.
Clear documentation of injuries can support more successful prosecutions and victims who are more likely to engage in the criminal justice process. The Department of Justice has recommended the use of alternate light to enhance bruise visualization. However, the technology has yet to be widely adopted in forensic examinations of violence victims likely due to 1 a knowledge deficit of the science behind alternate light among practitioners and 2 a dearth of research supporting its use.

A bruise, also called a contusion pronounced: kun-TOO-zhen , happens when a part of the body is injured and blood from the damaged capillaries small blood vessels leaks out. With no place to go, the blood gets trapped under the skin, forming a red or purplish mark that’s tender when you touch it — a bruise. Bruises can happen for many reasons, but most are the result of bumping and banging into things — or having things bump and bang into you.
Fortunately, as anyone who’s ever sported a shiner knows, the mark isn’t permanent. Bruises usually fade away in about 2 weeks. Over that time, the bruise changes color as the body breaks down and reabsorbs the blood. The color of the bruise can give you an idea how old it is:. Anyone can get a bruise. Some people bruise easily, while others don’t. Bruising depends on several things, such as:. Also, blood vessels tend to become fragile as people get older, which is why elderly people tend to bruise more easily.
Apply a cold compress to the bruise to help slow down the blood that’s flowing to the area, which decreases the amount of blood that ends up leaking into the tissues. It also helps keep the inflammation and swelling down.

Observers reported using color primarily to estimate age, followed by tenderness and then swelling; however, none of these factors was significantly correlated.
In this issue of the journal the possibility that heme oxygenase activity is responsible for the delay in the appearance of the yellow color in bruises has been investigated [ 1 ]. Bruises in the skin and subcutaneous tissues occur when there has been extravasation of blood following the application of blunt force. Generally the requirements for their formation are injury, compromise of the integrity of vessel walls, and blood pressure [ 3 ].
The most useful bruises in a forensic context are those that have a patterned appearance reflecting the nature of the impacting object. Questions that are commonly asked in court regarding bruises involve their age, the amount of force required for their production, and whether they occurred before or after death. Although it was once considered possible to provide answers to all of these queries, recent studies have shown that forensic assessments, particularly of the age of these injuries, may be less reliable than was previously considered.
Bruising basics: What to do when you’re black & blue
This is a bruise and is caused by an impact with a hard object or pressure that causes the blood vessels under the skin to burst and blood to leak out into the cellular space. Typically appears as a range of colors in a localized area on the skin. Current literature states that bruises cannot be reliably dated. The most common question I am asked is whether or not you can date bruises.

Related Editorial. Family physicians who are involved in the care of children are likely to encounter child abuse and should be able to recognize its common presentations. A history that is inconsistent with the patient’s injuries is the hallmark of physical abuse. A pattern of physical findings, including bruises and fractures in areas unlikely to be accidentally injured, patterned bruises from objects, and circumferential burns or bruises in children not yet mobile, should be viewed as suspicious for child abuse.
Family physicians who suspect physical abuse are mandated to make a report to the state child protective services agency and to assure the ongoing safety of the child. Physical abuse of children in our society is a serious problem that has only recently been recognized by the medical community. Anyone involved in the care of children is likely to see children who have been physically abused. In , approximately 1 million children were confirmed to be victims of maltreatment, and 1, children died from their injuries.

Once the bruise is formed, the body reacts by activating the inflammatory response. There are 2 types of inflammatory cells that migrate to the site of the bruise. Neutrophils are a type of white blood cell that arrive first. Then the macrophage cells, which are larger white blood cells, arrive later. Their arrivals to the injury occur at certain time intervals.
Detection and Visibility of Bruises Using Alternate Light: From of certain victims, particularly those who have darker skin color or delay seeking treatment. about two weeks of the live date and will be posted on our website.
The colors of a bruise appear courtesy of proteins being broken down inside the white blood cells. The first color is purple, which is caused by the hemoglobin being broken down and losing its oxygen. That happens immediately after the injury. The first breakdown product of hemoglobin is called biliverdin, which appears within a few days of the contusion and explains the greenish tint.
The green biliverdin is then converted to a yellow molecule called bilirubin. That process takes anywhere between a few days and several weeks, depending on the size of the bruise. Once bilirubin is made, it dissolves in the blood stream and is carried off to the liver and kidneys for final processing and excretion.

Why Do Bruises Turn Colors?
A bruise contusion happens when a blow to your body doesn’t break the skin but does break blood vessels beneath the skin. Blood leaking from the broken vessels causes redness and swelling. As it heals, your bruise is likely to turn colors like purple, green, and yellow. This is normal. The bruise should fade in 2 or 3 weeks.
Bruises occur when some type of trauma or injury crushes tiny blood As this happens, the color of the bruise can fade from dark to light Keep up to date on: Latest Buzz · Stuff Shows & Podcasts · Tours · Weird & Wacky.
A hematoma is a large collection of blood that becomes trapped within tissues. It is often related to more significant trauma. When a hematoma occurs, the body cannot heal the bruise as easily or quickly as a minor injury. As a result, a hematoma stays the same color, firmness, and causes the same level of pain even after several days. People may want to try to speed healing or lessen any pain associated with bruising. There are some potential at-home methods they can try, as described here:.
One of the first steps to helping a bruise heal is to apply ice to the area. People can ice the area with anything frozen, such as a freezer pack or a bag of frozen vegetables. Do not apply a cold pack directly to the skin, as this can cause further injury. When a person applies ice to a new bruise, it helps to slow bleeding down and lessen the swelling. This can reduce the overall size of the bruise, as it prevents blood from leaking further and reduces inflammation.
Many people use arnica, quercetin, vitamin B-3, or vitamin K creams to help speed up bruise healing times.
Can color inhomogeneity of bruises be used to establish their age?
As red blood cells degrade within a bruise, haemoglobin breaks down into bilirubin and biliverdin , and it is these pigments that pass through a series of colour changes. As these pigments resolve, the bruise changes in shape, size and location. Colour changes tend to begin at the margins of a bruise, and thus a large collection of blood will take comparatively longer to pass through a series of colour changes.
Traditionally, opinion regarding the ‘age’ of a bruise was based in large part on the colour of the bruise, and authors of forensic textbooks gave their own suggested ‘timetable’ of colour changes with time summarised in Langlois and Gresham There appeared to be a ‘consensus’ view that red, blue and purple were ‘early’ colours, greens appearing after days and yellow making a late appearance after at least 7 days. Yellow colouration appeared in bruises in calves, however, by 48 hours McCauseland and Dougherty
Are bruises present, and if so, where? This has been tried in the past, but dating injuries by using color tables is an imprecise method that cannot be used in.
This should not be done as it is too imprecise. Too many variables can affect the creation and resolution of a bruise. These include type of tissue injured loose tissue bruises earlier , mechanism of injury, length, duration of force, depth of injury superficial bruises appear earlier , skin color, health status of the patient, medications anticoagulants, antiplatelet agents, steroids , and age.
Bruises tend to show multiple colors as they age. Red and purple tend to be fresh. They then progress to blue, then to brown, yellow, or green. Some studies do indicate that yellow will not appear in a bruise until at least 18—24 hours after an injury. Riviello is professor of emergency medicine at Drexel Emergency Medicine in Philadelphia.

From a bump against a coffee table to a slip on the ice, we all know the resulting tenderness and kaleidoscope of colors that come with a bad bruise. And while those black-and-blue badges are part of everyday life, their cause, treatment and healing process are a bit of a mystery. A bruise is an injury to the small blood vessels under the skin.
The more serious the injury, the bigger the bruise, also known as a contusion. Contusions are usually more tender and painful to the touch than minor bruises to the skin. While a bruise is usually the result of outside force, like bumping into something, there are other causes, including certain medical conditions, such as kidney or liver disease; medical treatments or medications, including the anticoagulant Warfarin; and thinning skin that comes with aging. Most bruises are minor and will heal within two weeks.
There are some steps you can take to help speed healing and minimize swelling, discoloration and pain:. Not all bruises look the same or come with the same symptoms. For instance, an ecchymosis forms when broken blood vessels leak into the upper layers of the skin. A black eye is a common example. The affected area might be swollen, raised and painful.
