Usually when the small blood vessels in the skin are damaged, bruising will result. However, these bruises can change color during recovery, so many people think that the skin is yellow. The cause of yellow bruises on the skin is either a broken blood vessel under the skin or the bruise is healing.
1. The formation of yellow bruises on the skin Based on the color we can estimate the stage of the bruise. When the bruise is in the process of recovery, there is a process of breaking down hemoglobin and the compound that gives the blood red color that changes the color of the bruise. However, skin color also significantly affects their color. According to some studies, in people with medium skin tone bruises will be more red and yellow. In people with warmer skin tones, bruises will appear darker in color.
Change in color of bruises through stages:
In the early stages, when new bruises appear, they are usually red. This is because a lot of fresh blood (oxygen-rich blood) is concentrated under the skin. From 1 to 2 days later, the color will change because the blood gradually loses oxygen. The colors appear many: blue, purple, black. After 5 to 10 days, they may turn yellow or green due to the presence of biliverdin and bilirubin by hemoglobin degradation. This is also the reason for yellow bruises on the skin. From 10 to 14 days is the stage of turning yellow or light brown depending on each person's skin tone. At the final stage, they will begin to fade away. Most bruises will go away on their own in about 2 weeks without treatment.
