Honest Skincare Castor Oil Belly Button Roller 10mL

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.

What's in it

Cold-pressed, BioGro certified organic castor oil contains:

• Ricinoleic acid (~90%) — a unique hydroxyl fatty acid with documented anti-inflammatory properties
• Vitamin E (tocopherols) — an antioxidant that supports skin barrier function
• Omega-6 and Omega-9 fatty acids — known to support skin hydration and elasticity
