Does Castor Oil Help With Scars

Scars are a natural part of the body’s healing process, but they can often leave behind unwanted marks on the skin. Many people turn to different remedies and treatments in hopes of reducing the appearance of scars.

One popular remedy is castor oil, which has been used for centuries for its various medicinal properties. In this article, we will explore whether or not castor oil can truly help with scars.

Understanding Scars

Before delving into the effectiveness of castor oil on scars, it’s important to understand what exactly scars are and how they form.

Scars are formed when the dermis (the middle layer of skin) is damaged due to injury or trauma. This can be from a cut, burn, acne, surgery, or any other type of wound. When this happens, the body produces collagen fibers to repair and close the wound. However, these fibers are not arranged in the same way as regular skin tissue, resulting in a scar.

Different Types of Scars

There are several types of scars, including:

  • Keloid Scars: These scars are raised and extend beyond the original wound. They can be itchy and painful.
  • Hypertrophic Scars: Similar to keloid scars, these are also raised but they do not extend beyond the wound area.
  • Contracture Scars: These scars occur when the skin shrinks and tightens during the healing process. They can restrict movement if they form over a joint or muscle.
  • Acne Scars: These scars are caused by severe acne and can appear as either deep pits or raised bumps on the skin.

What is Castor Oil?

Castor oil is derived from the castor bean plant and has been used for therapeutic purposes for centuries.

Chemical Composition of Castor Oil

  • Ricinoleic acid: This is the main component of castor oil and makes up about 90% of its composition. It has anti-inflammatory properties that can help decrease redness and swelling.
  • Oleic acid: This fatty acid helps to moisturize the skin and improve its barrier function.
  • Linoleic acid: Another fatty acid that helps to maintain skin hydration.

Does Castor Oil Help Reduce Scars: The Truth

Does Castor Oil Help Reduce Scars

The short answer is yes, castor oil can help reduce the appearance of scars. However, it is important to note that there is limited scientific evidence to back this claim.

One study found that applying a mixture of castor oil and vitamin E on post-surgical scars for 8 weeks resulted in significant improvement in scar appearance compared to just using vitamin E alone.

Benefits of Castor Oil for Scars

Moisturizing: Castor oil has a thick consistency that helps to lock in moisture. This can be beneficial for scars as moisturized skin tends to heal better.

Anti-inflammatory properties: As mentioned earlier, castor oil contains ricinoleic acid which has anti-inflammatory properties. This can help reduce any redness and swelling associated with scars.

Antioxidant effects: Castor oil also contains antioxidants that can help fight off free radicals and promote skin repair. This can be beneficial for healing scars.

Improves skin elasticity: Castor oil contains fatty acids that help to improve the skin’s elasticity. This can help reduce the appearance of scars by making them less noticeable.

How to Use Castor Oil for Scars

To effectively use castor oil for scars, it’s important to follow a consistent routine. Here is a simple method you can use:

  1. Clean the Area: Begin by cleansing the scar and surrounding skin to ensure it’s free from dirt and oils. Pat the area dry gently.
  2. Apply Castor Oil: Take a small amount of castor oil on your fingertips. Rub it between your fingers to warm it up slightly, then gently massage it onto the scar. Use circular motions to help the oil penetrate deeply.
  3. Cover the Scar (Optional): For deep penetration, you can cover the treated area with a clean cloth or plastic wrap and leave it on for at least one hour or overnight. This step is optional but can be beneficial for intensive treatment.
  4. Rinse Off: After the treatment period, wash the area with warm water and a gentle cleanser. Pat dry with a clean towel.
  5. Repeat: To see the best results, apply castor oil to your scar daily. It may take several weeks or even months to notice significant improvements, depending on the age and severity of the scar.

Potential Side Effects

While castor oil is generally considered safe for topical use, there are a few potential side effects to be aware of:

Skin Irritation: Some individuals may experience skin irritation or allergic reactions when applying castor oil, especially those with sensitive skin.

Folliculitis: Although rare, overuse of castor oil can clog pores and lead to folliculitis, a condition characterized by inflamed hair follicles.

Discoloration: In very rare cases, prolonged use of castor oil on scars may lead to skin discoloration.

Interference with Wound Healing: Applying castor oil on fresh wounds or unhealed scars could potentially interfere with the natural healing process.

Precautions and Tips

  1. Always do a patch test before using castor oil on large areas of skin.
  2. Consult with your doctor first, especially if you have any pre-existing skin conditions or allergies.
  3. Avoid using castor oil on open wounds or fresh scars.
  4. If you experience any adverse reactions, stop use immediately and pursue medical advice.
  5. Use pure, cold-pressed castor oil for best results.

Other Treatments for Scars

  1. Silicone Sheets and Gels

Silicone sheets and gels are widely recognized for their efficacy in scar treatment. They work by hydrating the scar tissue, which helps to reduce its size and improve its texture over time. These products create a protective barrier over the scar, maintaining moisture and encouraging the scar to heal in a less noticeable form.

  1. Laser Therapy

Laser therapy is a more advanced treatment option that involves the use of focused light to reduce scar appearance. This technique can minimize the redness of scars, smooth out their texture, and even improve the elasticity of the skin around the scar.

  1. Steroid Injections

These injections can help to flatten and soften the scars, making them less noticeable. This method is particularly effective for scars that are raised above the skin’s surface but may require multiple sessions to achieve the desired results.

  1. Surgical Removal

In cases where other treatments are not effective, surgical removal of the scar may be an option. This procedure involves cutting out the scar tissue and using stitches to close the wound.

  1. Natural Remedies

Aside from medical treatments, there are several natural remedies believed to help with scar healing. These include aloe vera, honey, and onion extract, among others. While the scientific evidence supporting their effectiveness is limited, some individuals may find these options beneficial for mild scarring.


While castor oil may not be a miracle cure for scars, it does have moisturizing, anti-inflammatory, and antioxidant properties that can help improve their appearance. However, it’s important to remember that results may vary from person to person, and more severe or older scars may require medical treatments.

Key Takeaways

  • Castor oil has moisturizing, anti-inflammatory, and antioxidant properties that can help improve the appearance of scars.
  • To use castor oil for scars, cleanse the area, apply the oil, cover it (optional), rinse off after the treatment period, and repeat daily.

There is not enough scientific evidence to support this claim. While castor oil may help improve the appearance of scars, it’s unlikely that it can break down internal scar tissue.

Does castor oil help remove acne scars?

While castor oil may help improve the appearance of acne scars, it’s not a guaranteed solution for scar removal. Consistent use, along with other treatments and good skincare habits, can lead to better results in reducing the appearance of acne scars.
