What is Castor Oil?

Castor oil is a vegetable oil extracted from the seeds of the Ricinus communis plant L., which grows in tropical regions around the world, particularly in Africa, South America and India. Known for its rich nutrient profile, castor oil has been used for centuries in traditional medicine across cultures. In ancient civilizations like Egypt and China, it was prized for its versatility, serving as a base for ointments and perfumes.

The primary component of castor oil is ricinoleic acid (RA), an omega-9 fatty acid that comprises about 90% of its fatty acid profile. This unique composition gives castor oil its potent properties, including anti-inflammatory, analgesic (pain-relieving) and antibacterial. Additionally, castor oil contains beneficial compounds such as tocopherols (vitamin E), which are natural antioxidants, and other fatty acids like linoleic and oleic acids that are good for the skin.

Historically, castor oil has been used for a wide range of health and wellness applications, including as a FDA-approved laxative, pain reliever, wound-healing aid and more. With its rich nutrient profile, castor oil may offer a plant-based alternative to conventional skincare ingredients.

Benefits of Using Castor Oil on Your Face

Moisturizing

Castor oil can serve as an occlusive moisturizer, which forms a protective barrier on the skin to lock in moisture, keeping skin hydrated. With its high concentration of RA, it also helps maintain a soft, smooth skin texture. Since RA has antibacterial properties, it may also soothe itchiness and irritation while keeping skin moisturized.

Anti-Aging Benefits

Castor oil contains tocopherols, which deliver essential antioxidant benefits that help protect the skin from free radicals. Free radicals are reactive molecules produced in response to environmental stressors like UV radiation and pollution, which lead to oxidative stress that can degrade the skin’s essential proteins — collagen and elastin. This damage accelerates visible aging signs, such as wrinkles and a reduction in firmness​. Antioxidants can neutralize these free radicals before they can cause structural damage​, thereby supporting the skin’s youthful appearance over time. 

Acne Control

Since castor oil has antibacterial and anti-inflammatory properties, it could be used to treat acne. By inhibiting the growth of various bacteria, castor oil can help prevent the buildup of bacteria on the face, which can clog pores and lead to acne. Its anti-inflammatory effect may also help soothe inflamed skin and swelling often accompanying acne. 

Evens Skin Tone

Since castor oil offers anti-inflammatory benefits for the skin, it may help reduce redness and puffiness. A study showed that repeated topical application of RA can inhibit inflammation and edema without causing the irritation seen with capsaicin, a similar agent.

Castor oil has also long been used in Persian medicine to address skin hyperpigmentation. A recent study confirmed that a 10% castor oil cream applied twice daily over two months significantly reduced the appearance of infraorbital dark circles (hyperpigmentation under the eyes), improving melanin levels and creating a more even skin tone.

How To Use Castor Oil on Your Face

  1. Patch Test Before Full Application: To avoid a potential allergic reaction, patch test on a small area of skin before applying it fully to the face.
  2. Cleanse: Start with a clean face to allow the castor oil to absorb better.
  3. Apply a Small Amount: Pour a few drops of castor oil onto your fingertips.
  4. Massage Gently: Use your fingers to massage the oil onto your face in upward, circular motions. This helps promote absorption and circulation.
  5. Focus on Specific Areas: If targeting areas like under-eye circles, apply a small amount and tap gently around the area.

Is Castor Oil Good for My Skin Type?

Dry Skin

Castor oil’s hydrating properties make it a beneficial option for those with dry skin. As an occlusive moisturizer, it forms a barrier that locks in moisture, helping to keep dry skin hydrated and maintaining a soft, smooth feel

Oily Skin

For people with oily skin, castor oil may not be the ideal choice due to its rich texture and high fatty acid content. Many dermatologists recommend oil-free moisturizers for oily skin types to prevent excessive oil buildup, which can sometimes contribute to clogged pores. 

Sensitive Skin

Sensitive skin may benefit from castor oil’s anti-inflammatory effects. The natural compounds within castor oil, particularly ricinoleic acid, can help soothe inflammation, making it a gentle option for sensitive skin types. Patch testing is especially important for sensitive skin to ensure a positive experience.

When To Avoid Using Castor Oil

  • While Pregnant: Pregnant women should take care not to ingest castor oil while using it due to potential risks, including severe gastrointestinal distress, diarrhea, dehydration and intense and irregular uterine contractions.
  • If Irritation Occurs: If you notice any redness, itching or discomfort after applying castor oil, discontinue use immediately.

Consult a Doctor With Any Concerns: If you have specific skin conditions or are unsure how castor oil may interact with other skincare products, consult a dermatologist or healthcare provider.
