Purple Spot On Lip: What Causes It?

Causes of Purple Spots on the Lip

Have you ever noticed a purple spot on your lip and wondered what it could be? Don’t worry, you’re not alone. Many people see spots or patches on their lips and get curious or even a little worried. Let’s explore what these purple spots are and what might cause them.

What is a Purple Spot?

A purple spot on the lip is a small area that appears darker than the surrounding skin. It might be light purple or dark purple, which can occur suddenly or over time. Purple spots can vary in size and shape.

Common Causes of Purple Spots on the Lip

1. Injury or Trauma

  • Biting Your Lip: If you’ve ever accidentally bitten your lip, you know it can hurt. Biting your lip can cause a bruise, which might look like a purple spot.
  • Bumping Your Lip: Sometimes, bumping your lip on something hard can cause a bruise. The tiny blood vessels under your skin break, causing blood to collect and form a bruise.

2. Blood Blisters

  • What Are They? Blood blisters are small, raised bumps filled with blood. They can happen if you pinch or injure your lip.
  • How Do They Form? When the skin gets pinched or damaged, the blood vessels underneath can break. The blood gets trapped under the skin, forming a blister that looks purple or dark red.

3. Allergic Reactions

  • Allergic to What? Sometimes, people are allergic to certain foods, lip balms, or even toothpaste. If you’re allergic to something that touches your lips, it can cause irritation or spots.
  • Symptoms: Along with purple spots, you might notice itching, swelling, or a rash on your lips.

4. Sun Exposure

  • Why the Sun? Just like your skin can get sunburned, your lips can too. Too much sun can damage the skin on your lips, causing spots and discoloration.
  • Protection: To protect your lips, use a lip balm with SPF. It works just like sunscreen for your lips

5. Medications

  • Side Effects: Some medicines can cause your lips to change colour or develop spots. Although it happens rarely, it is possible.
  • What to Do: If you notice spots after starting a new medication, talk to your doctor. They can help figure out if the medicine is causing the problem.

6. Lack of Vitamins

  • Important Vitamins: Your body needs certain vitamins to stay healthy, like vitamins B and C. If you’re not getting enough of these vitamins, it can affect your skin, including your lips.
  • Healthy Eating: Eating a balanced diet with fruits, vegetables, and whole grains can help keep your lips healthy.

7. Infections

  • Bacterial or Viral Infections: Sometimes, infections can cause spots or sores on your lips. These might be caused by bacteria or viruses.
  • Cold Sores: One common viral infection is a cold sore, which can look like a red or purple blister. Cold sores are caused by the herpes simplex virus and can be painful.

8. Medical Conditions

  • Angiokeratomas: These are small, dark spots caused by blood vessels near the surface of the skin. They are usually harmless but can sometimes be confused with other conditions.
  • Venous Lakes: These are small, dark blue or purple spots that usually appear on the lower lip. They are caused by dilated veins and are common in older adults.

When to See a Healthcare Provider

Most purple spots on the lips are harmless and go away on their own. However, there are times when you should see a dentist near you:

  • Persistent Spots: If the spot doesn’t go away after a couple of weeks,.
  • Pain or Discomfort: If the spot is painful or makes it hard to eat or talk.
  • Other Symptoms: If you have other symptoms like fever, swelling, or difficulty breathing.
  • Changes in Size or Colour: If the spot changes size, shape, or colour quickly.

How to Prevent Purple Spots on Your Lips

  1. Be Careful: Avoid biting or injuring your lips. Take care when eating or playing sports.
  2. Use Sun Protection: Apply lip balm with SPF to protect your lips from the sun.
  3. Stay Hydrated: Drink plenty of water to keep your skin, including your lips, hydrated.
  4. Eat a Healthy Diet: Make sure you’re getting enough vitamins and nutrients by eating a variety of healthy foods.
  5. Avoid Allergens: If you know you’re allergic to certain foods or products, avoid them to prevent reactions on your lips.
  6. Practice Good Hygiene: Keep your lips clean and moisturized. Use a gentle lip balm to keep them soft.
