Bruises, also known as contusions, typically turn purple before transitioning to a yellow hue. This color change is part of the body’s natural healing process as it breaks down hemoglobin in the blood.

What Causes Bruises to Change Color?

Bruises change color as the body metabolizes the blood that has leaked from damaged blood vessels. Initially, a bruise appears red due to fresh oxygen-rich blood pooling under the skin. Within a day or two, it turns bluish-purple or black as the oxygen is used up and the hemoglobin in the blood begins to break down. Over the next few days, the bruise may shift to a green color, then to yellow or brown as the hemoglobin further degrades into biliverdin and bilirubin.

How Long Does It Take for a Bruise to Heal?

The healing time for a bruise can vary depending on its severity and location. Generally, bruises take about two weeks to heal completely. However, larger bruises or those on areas with less flesh, like the shin, may take longer. Factors such as age, medication use, and overall health can also influence healing time.

Stages of Bruise Healing

1. Day 1-2: Red to purple or black.
2. Day 3-5: Blue to dark purple.
3. Day 6-10: Green to yellow.
4. Day 11-14: Light brown to fading.

Why Do Some People Bruise More Easily?

Some individuals bruise more easily due to factors such as:

• Age: Older adults often have thinner skin and more fragile blood vessels.
• Medications: Blood thinners, aspirin, and certain supplements can increase bruising.
• Medical conditions: Disorders like hemophilia or vitamin deficiencies can lead to increased bruising.

How to Speed Up Bruise Healing

While bruises generally heal on their own, there are steps you can take to expedite the process:

• Ice the area: Apply a cold compress for 15-20 minutes to reduce swelling.
• Elevate the limb: Raising the affected area can decrease blood flow and swelling.
• Use compression: A bandage can help minimize swelling and provide support.
• Apply heat: After 48 hours, use a warm compress to boost circulation and healing.
• Consider topical treatments: Arnica gel or vitamin K cream may help reduce bruising.

When Should You See a Doctor for a Bruise?

Most bruises are harmless and resolve on their own. However, consult a healthcare professional if you experience:

• Unexplained bruising: Especially if it occurs frequently or without injury.
• Severe pain: Accompanied by swelling or difficulty moving a joint.
• Bruises that don’t heal: After two weeks.
• Signs of infection: Such as redness, warmth, or pus.

People Also Ask

Why Do Bruises Hurt?

Bruises cause pain because of the inflammation and pressure on nerve endings from the pooled blood under the skin. The pain usually subsides as the bruise heals.

Can Bruises Be Prevented?

While not all bruises can be prevented, wearing protective gear during sports, using caution to avoid falls, and managing medications that affect blood clotting can help reduce the risk.

Is It Normal for a Bruise to Itch?

Yes, itching can be a normal part of the healing process as new skin cells form and the body reabsorbs the blood from the bruise. However, excessive itching or other symptoms may require medical attention.

What Are the Different Types of Bruises?

Bruises can vary in type, including:

• Subcutaneous: Occur beneath the skin.
• Intramuscular: Occur within the muscle.
• Periosteal: Occur on the bone.

How Do You Know if a Bruise Is Serious?

A serious bruise may be accompanied by extreme pain, swelling, or difficulty moving the affected area. If you suspect a fracture or internal bleeding, seek medical attention immediately.
