Why Do Bruises on Our Skin Change Color While Healing?

These injuries cause bleeding under the skin, It turns from purple to green, and from green to yellow.

Alright the reason for this change Have you ever wondered?

First of all, we need to look at how these bruises form.

Bruises on our skin are mostly blood due to damage to small blood vesselsIt occurs as a result of leakage between tissues. If the skin is damaged, bleeding occurs.

As you may have noticed, after an injury, the damaged area is red. The reason of this, It is the blood that leaks between the tissues. Hemoglobin, which gives blood its color, is also responsible for carrying oxygen to the tissues.

If oxygen is bound to hemoglobin, the injured area will be red.

What about when oxygen is not bound? The answer to our question actually lies here. Because when oxygen is not bound, the color changes to shades of blue and purple as the blood loses oxygen.

Bruises undergo a major color change during the healing process. The main reason for this color change is the biochemical transformations of hemoglobin, which plays a role in the formation of bruises. Hemoglobin found in the bruiseIt is broken down by special cells called macrophages.

One of the molecules released during this breakdown process is biliverdin, which has a greenish color.

Over time, biliverdin, another yellow molecule, turns into bilirubin. These chemical transformations cause the bruise to change color over time, changing from purple to green and then yellow.

In general recovery two weeks after injuries occurs and the skin texture returns to normal. The reason behind these rainbow-like changes is actually that simple!
