Why Do Surgical Scars Turn Purple? Is It Normal?

If you've recently had surgery, you may be surprised to see your incision changing color. A once-red incision can gradually become pink, purple, or even slightly blue as it heals.

In most cases, a purple surgical scar is a normal part of the healing process. However, the exact reason behind this color change isn't always obvious, and the timing, appearance, and duration can vary from person to person. 

In this article, we'll explore why surgical scars become purple, how long purple scars usually take to fade, when the color is considered normal, and ways to support healthy scar healing.

Common Reasons Surgical Scars Turn Purple

During the weeks following surgery, your body enters an active repair phase. The purple color you see is often a sign that your body is working to heal the incision rather than an indication that something is wrong.

Several factors contribute to the temporary discoloration of surgical scars. 

1. Increased Blood Flow

After surgery, your body increases blood circulation around the incision to support healing. This process:

• Delivers oxygen

• Supplies nutrients

• Repairs damaged tissue

• Makes the scar appear purple

2. New Blood Vessels Formation

As part of healing, your body creates new capillaries around the incision. These delicate blood vessels support tissue repair but can temporarily make scars appear darker or more purple until they mature.

3. Normal Inflammation

Inflammation is one of the first stages of wound healing (1). While many people associate inflammation with infection, mild inflammation is actually essential for repairing tissue. During this phase, scars often appear purple.

4. Scar Maturation & Collagen Remodeling

When a surgical wound heals, your body constantly disassembles and rebuilds collagen, the protein, which is responsible for giving your skin both its strength and structure. Throughout this process, the scar tissue is still forming, and the small blood vessels embedded within the scar remain rather apparent. This may make your scar appear while it matures. 

Over time, as collagen reorganizes and the blood vessels gradually decrease, the scar typically becomes flatter, softer, and lighter in color.

5. Changes in Skin Pigmentation

Pigment changes can vary depending on:

• Natural skin tone

• Individual melanin production

• The amount of inflammation during healing

• Exposure to the sun during the scar's maturation

Is it normal for a Surgical Scar to Be Purple?

Yes. In most cases, a purple surgical scar is completely normal.

Fresh surgical scars rarely remain the same color throughout healing. They often progress through several stages before reaching their final appearance.

How to Help Purple Scars Heal

1) Support Collagen Remodeling With Good Nutrition

Your body is still rebuilding and reorganizing collagen for months following surgery. Protein, vitamin C, zinc, and other nutrients serve as the building blocks for healthy collagen formation and scar maturation.

HealFast offers physician-formulated surgery recovery supplements that contain these key nutrients to help support your body's natural healing process before and after surgery. They are designed to complement a balanced diet, not replace it. 

2) Avoid Activities That Place Excessive Tension on the Scar

Over-stretching or pulling the healing incision can put more tension on the scar tissue as collagen forms. Following your surgeon's activity recommendations allows collagen to organize more evenly as the scar matures.

3) Use Medical-Grade Silicone

Once the incision has fully closed, medical-grade silicone helps maintain hydration of the scar tissue, which is considered one of the primary mechanisms behind its role in scar management (3). A well-hydrated scar creates an environment that supports healthy collagen remodeling and may improve the scar's color, texture, and overall appearance over time.

Depending on your scar's location and your personal preference, you can choose from different forms of medical-grade silicone therapy:

• Silicone Scar Gel: Perfect for scars on face, joints, or anywhere you really want a light, nearly invisible application. The gel dries quickly, creating a protective silicone layer right over your scar.
  

• Silicone Scar Tape: Great for bigger scars or areas with a lot of movement, like your stomach, shoulders, knees, or elbows. Silicone tape gives you constant silicone coverage all the time, while staying very flexible and is rather easy to cut to fit your needs perfectly.
  

• Silicone Scar Sheets: These are pre-cut, reusable silicone strips ready to go, giving you consistent silicone coverage. They're quite convenient indeed for helping scars heal better post-surgery.

4) Protect the Scar From Sun Rays

Healing scars are more sensitive to ultraviolet (UV) rays. Exposure to the sun can really worsen scar discoloration by boosting pigment production, making your purple scar appear darker or take longer to fade. Keeping your scar covered with clothes or using sunscreen after the wound has closed can help minimize these changes.

5) Don't Smoke

Smoking reduces blood flow and oxygen delivery to healing tissues (4), slowing the body's natural repair process. Avoiding smoking helps support tissue healing and normal scar maturation.

6) Be Patient With the Healing Process

Purple scars usually fade as healing progresses. Over time, new blood vessels become less prominent, and collagen continues to remodel, gradually making the scar flatter, softer, and lighter in color.

7) Track Your Scar Colour Over Time 

Scar color changes happen gradually, not overnight. Instead of checking your scar every day, compare photos every few weeks. If your scar is gradually becoming lighter over time, it's often following a typical healing pattern, although it might still look quite purple.

While every scar heals differently, the table below outlines the most common reasons a surgical scar may appear purple and the recommended care strategies.
