If there’s one natural product I always recommend having in your bathroom, it’s 100% pure, cold-pressed castor oil.

This thick, golden oil has been used for centuries in traditional beauty and wellness routines, and while it’s incredibly simple, it’s one of the hardest-working products you can own. From deeply nourishing dry skin to encouraging healthier-looking brows and lashes, castor oil has become a staple in my self-care routine.

One trend that’s become especially popular is applying castor oil to your belly button before bed as part of an evening wellness ritual. While scientific evidence on this specific practice is limited, many people enjoy it as a relaxing tradition and report waking up with softer skin and feeling more hydrated.

Let’s dive into why castor oil deserves a place in your daily routine.

1. Deeply Moisturises Dry, Ageing Skin

As we move through our 40s and into perimenopause, our skin naturally becomes drier because our estrogen levels begin to decline.

Castor oil is packed with ricinoleic acid, a unique fatty acid that helps lock moisture into the skin. Unlike many commercial moisturisers that simply sit on the surface, castor oil creates a protective barrier that helps prevent water loss.

Regular use can help improve the appearance of:

• Dry patches
• Flaky skin
• Rough elbows and knees
• Cracked heels
• Chapped lips

I love applying a tiny amount before bed and waking up with soft, glowing skin.

2. May Help Reduce the Appearance of Fine Lines

No oil can erase wrinkles overnight, but hydrated skin naturally looks smoother and plumper.

Because castor oil is such an effective moisturiser, it may soften the appearance of fine lines caused by dryness and dehydration. Keeping the skin well hydrated also supports a healthy skin barrier, which becomes even more important during perimenopause.

Try gently massaging a drop around crow’s feet, smile lines, or your neck before bed.

3. Fuller Looking Eyebrows and Healthier Lashes

One of the most popular beauty uses for castor oil is nourishing eyebrows and eyelashes.

Although research hasn’t shown that castor oil directly stimulates hair growth, it can help condition the hair and reduce breakage, making brows and lashes appear fuller and healthier over time.

Simply apply a tiny amount with a clean spoolie brush before bed, being careful to avoid getting it into your eyes.

4. A Dry, Itchy Scalp’s Best Friend

If you suffer from an itchy scalp, dandruff, or dryness, castor oil can provide intense moisture.

Massage a small amount into your scalp before washing your hair. Many people find this leaves their scalp feeling calmer and their hair looking shinier.

Because castor oil is very thick, mixing it with lighter oils like jojoba, argan, or coconut oil can make it easier to apply and rinse out.

5. The Belly Button Castor Oil Trend

One of the latest holistic wellness trends is applying a few drops of castor oil into the belly button before sleep.

This practice comes from traditional wellness systems, including Ayurveda, where the navel is viewed as an important area of the body.

While there isn’t strong scientific evidence that applying castor oil to the belly button directly improves gut health or detoxification, many people enjoy it as a calming nighttime ritual. Some also find that regular use helps keep the surrounding skin soft and hydrated.

If you’d like to try it:

• Place 2–3 drops of castor oil into your belly button before bed.
• Gently massage the surrounding area for a minute or two.
• Wear older sleepwear, as castor oil can stain fabrics.

Think of it as a relaxing self-care practice rather than a medically proven treatment.

6. Can It Support Gut Health?

Castor oil has a long history of use as a stimulant laxative when taken orally, but this should only be done under appropriate medical guidance because it can cause significant side effects.

Applying castor oil to the skin or belly button has not been proven to improve gut health. However, some people include it as part of a broader evening routine that also focuses on hydration, fibre-rich foods, movement, stress reduction, and quality sleep—all of which do support digestive health.

Why I Love Castor Oil

What I love most is that one affordable bottle can replace multiple beauty products.

Instead of buying separate products for dry skin, lips, brows, cuticles, heels, and scalp, I simply reach for my castor oil.

As women navigating perimenopause, our bodies often need a little extra nourishment, and simple, natural products like castor oil can be a wonderful addition to a consistent self-care routine.

My Favourite Ways to Use Castor Oil

✔ Overnight facial moisturiser (use sparingly if you’re acne-prone)

✔ Dry elbows, knees and heels

✔ Eyebrows and eyelashes

✔ Cuticle treatment

✔ Scalp massage before washing

✔ Belly button massage as part of a relaxing nighttime ritual

✔ Dry hands and cracked feet

Final Thoughts

Natural wellness doesn’t have to be expensive. Sometimes the simplest remedies have stood the test of time for a reason.

While castor oil isn’t a miracle cure, it can be an excellent moisturiser and conditioning treatment for skin, hair, brows, and scalp. If you’re curious about the belly button trend, there’s little harm in trying it as a calming ritual—just keep your expectations realistic, as claims about gut health and detoxification haven’t been confirmed by strong scientific research.

If you’re looking for one affordable product to nourish your skin from head to toe, 100% pure, cold-pressed castor oil is definitely worth adding to your wellness routine.
