Keloids are primarily a cosmetic concern and not much of a health concern. They appear when there is an overgrowth of scar tissues. The appearance of keloids on the face or chest may make the individual over-conscious about their appearance. While there are surgical options to minimize their appearance, tea tree oil is touted to be an effective non-surgical way to treat keloids.

There are no studies to support that tea tree oil can treat existing keloids. However, there are ways you can use tea tree oil to reduce the chances of developing keloids. Scroll down for more information.

What Are Keloids?

Keloids are raised scar tissues that occur on the site of injury. They can occur when your skin receives an injury due to surgery, trauma, piercings, blisters, vaccinations, and acne. Keloids are different from normal scars.

A keloid is much larger and raised than the original wound. Usually, your skin heals itself when it is injured. The wound closes, and a scar forms in that place. However, unlike normal scars, keloid scar tissues will continue to grow (like a raised bump) even after the wound is closed. They become much larger and keep growing until they reach a final size.

The scar may look like a lump of flesh, and it is often itchy. Usually, keloid scars are not harmful and are not a major health concern. However, they may cause minor discomforts, such as irritation, itching, and tenderness.

Your genes may also be responsible for keloids. As per researchers at the Henry Ford Hospital, those who have an altered gene called AHNAK, are prone to develop keloids (1). However, more studies are required to conclude the role of genetics in keloid development.

Treating keloids can be tricky. There are surgical options, but the scar tissue can reappear while your skin is trying to repair itself. Hence, people often resort to home remedies to manage keloids. Tea tree oil is a widely used at-home treatment option for keloids. But is it helpful? Let’s find out.

Can Tea Tree Oil Treat Keloids?

If it is an existing keloid, no, tea tree oil cannot treat it.

You will find plenty of articles on the internet that claim that tea tree oil can treat keloid scars. However, there is no scientific proof to back the claim. Scars, be it keloids or any other type of scars, are tough to remove, even after professional treatment. You can only minimize their appearance.

However, tea tree oil can help reduce the risk of developing keloid scars. Any wound needs proper healing. If it doesn’t heal properly, it may leave a scar. Tea tree oil can promote proper healing of your wound and help minimize the chances of developing a keloid scar.

This is primarily because:

  • Tea tree oil has antimicrobial and anti-inflammatory properties (2). This means it can prevent infections and reduce inflammation, aiding proper wound healing.
  • Tea tree oil also has antiseptic properties (3). Fresh cuts and wounds are prone to infection, which can delay the healing process and increase your risk of scarring. Tea tree oil can prevent the growth of microbes and heal the wound faster.

Whether you have got a piercing (on nose, chest, earlobes, etc.) or acne, cuts, and wounds, these properties of tea tree oil can help:

  • Prevent fungal infection
  • Reduce inflammation, including redness and irritation
  • Minimize the pus-filled bumps and pustules that you might have developed

If you have any cuts, wounds, or injury, you may take preventive measures by using tea tree oil. However, none of the studies are conclusive, so be careful while using the oil. Scroll down to find ways to use tea tree oil to prevent keloid scars.

How To Use Tea Tree Oil For Preventing Keloids

Note: Undiluted tea tree oil is very potent. Dilute it with any carrier oil (jojoba, almond, olive, or virgin coconut oils) before using it.

For all the following recipes, mix 2-3 drops of tea tree oil in a tablespoon of any carrier oil and then use the blend. Follow the same proportion for all essential oils.

Also, do not apply any of these concoctions on an open wound. Once the wound starts healing, use the recipes to speed up healing and prevent keloids.

Although tea tree oil is harmless, it may cause an allergic reaction due to which you may develop:

  • Redness

You may opt for surgical removal or laser treatment. Discuss the pros and cons of the methods with your doctor and be aware of your eligibility for the treatment options.

Better wound management can help prevent scarring and keloid formation.
