The navel (umbilicus) is one of the body's most absorbent areas — rich in connective tissue and in close proximity to key abdominal structures. Applying castor oil transdermally via the navel has been used for centuries, and modern interest in transdermal absorption continues to grow.
The Honest Skincare Belly Button Roller makes this ritual precise, clean, and genuinely practical.

The navel (umbilicus) is one of the body's most absorbent areas - rich in connective tissue and in close proximity to key abdominal structures. Applying castor oil transdermally via the navel has been used across cultures for centuries, and modern interest in transdermal absorption continues to grow.
The Honest Skincare Belly Button Roller makes this ritual precise, clean, and genuinely practical.
Formulated with 100% cold-pressed, BioGro Certified Organic castor oil (Ricinus communis), it delivers the full nutritional profile of the oil — including ricinoleic acid, vitamin E, and omega-6 and omega-9 fatty acids — without fillers, additives, or the mess of traditional bottle application.
Why a glass roller?
Our roller uses a smooth glass ball applicator. Glass is chemically inert — it won't interact with or degrade the oil over time, and it won't leach synthetic compounds. It also delivers a naturally cooling sensation on contact, which can help with under-eye puffiness and sensitive facial skin in addition to navel oiling.

People apply castor oil to the belly button for a range of reasons:
Pregnant women — Castor oil can stimulate uterine contractions and has historically been used to induce labor, so topical use (especially in large amounts or on the abdomen) is generally advised against during pregnancy.
People with known allergies to castor oil or the castor bean plant (Ricinus communis) -There are a very small percentage of people who are allergic to castor oil. Allergic reactions can range from mild redness and itching to more severe contact dermatitis. Always do a small patch test on the inside of your wrist 24 hours before using.
People with open wounds, broken skin, or active skin infections - do not use on broken skin.
