Contains Ricinoleic Acid

Castor oil contains ricinoleic acid, a fatty acid that has anti-inflammatory properties. This can help nourish hair follicles on your eyelid, encouraging growth.

Question 1: How long does it take to see results from castor oil?
Answer: Most people see results in 4-6 weeks with consistent application several times per week. Give it 2-3 months for full effects.

Question 2: Does castor oil change eye color?
Answer: No, castor oil does not alter eye color. It may only temporarily lighten iris color by lightening pigment in the top layer of colored cells.

Question 3: Can I apply castor oil to my eyelashes during the day?
Answer: It’s best to apply castor oil before bed and wash off in the morning rather than keeping it on all day. Reapply during daylight hours only if irritation doesn’t occur.

Question 4: Does castor oil grow eyebrows too?
Answer: Yes, castor oil can be used along the eyebrows in the same way as the lashes. It nourishes follicles for fuller, thicker brow growth.

Question 5: Is castor oil safe if it gets in your eyes?
Answer: Pure castor oil is generally safe if a small amount gets in your eyes. Flush eyes with water or saline solution. Discontinue use if irritation continues.

While you can technically leave castor oil on all day, washing it off after letting it soak in overnight is recommended. This prevents irritation and blurred vision while still allowing the castor oil to work its magic. Follow best practices like alternating nights and mixing with other ingredients for a simple, natural way to achieve longer, fuller lashes.
