The 6 Benefits of Using Castor Oil for Eyes

Anything you put in or around your eyes should be approached with care. However, castor oil is a tried-and-tested method. Castor oil contains naturally occurring ricinoleic acid, omega-6 fatty acids, and triglycerides. Let’s explore how these active ingredients can boost your eye and skin health.

Castor Oil for Eyes

1) Soothes Dryness, Itching and Puffiness

Castor oil’s anti-inflammatory and antimicrobial properties enable it to soothe irritation around the eye area. You can use it either through eye-drops, or topical application.

Triglycerides in castor oil boost moisture levels, and its humectant properties also help the skin to draw moisture from the air, keeping it hydrated.

1. Does castor oil really make eyelashes or hair grow?

Yes – the ricinoleic acid and fatty acids present in castor oil can increase blood circulation and nourish your hair follicles. When the hair follicles are in healthy stage, the hair will growth stronger and fuller.

2. Is it safe if I get castor oil accidentally into my eyes?

It is generally safe if you get castor oil into your eyes. It was used for eye cataract treatment decades ago although there was no anecdotal evidence supporting this. New studies have found that castor oil is not be effective in treating cataract. However, its mild characteristics will not cause harm if you get it accidentally into your eyes.

However, a small number of people can be allergic to castor oil. Therefore, for a safety measure, test a drop of castor oil on your hand first. You can wait for an hour to make sure your skin has no allergic reaction to it, before applying to your eyes’ area.

3. Where can I apply castor oil besides eye?

Eyebrow, hair, nail, face, body, stretch mark, scars, acne, beard.

4. How long does it take to grow the lashes longer?

Genetics determine the growth rate of your hair. However, the rate can change depending on your follicle health, your hair care practices and hormonal change. Using castor oil around your lashes, can nourish your follicle with nutrients. This will speed up the growing process. It normally takes around 3+ months for most users to see a difference.

5. What are the side effects of using Castor oil on eyes?

For users who apply the oil directly into eyes, it may cause blurry vision. But once your eye has absorbed the liquid, the vision should be cleared after a few moments.

It’s important to test the castor oil on a small area of your skin on hand to see if you have any allergic reactions first. (Before you apply it around the eye area). Some people may experience a redness or itchiness of skin due to allergic reaction. Other possible side effects are diarrhea, cramps, nausea etc.

6. How to pick a good Castor Oil brand?

When shopping for castor oil, it is important to look for brands that is “hexane-free”. Hexane is a chemical that is used when extracting oil from a plant’s seed. Hexane is a relatively inexpensive and fast extraction process used by a number of brands.

A study from US Environmental Protection Agency has found that hexane can cause “mild central nervous system (CNS) effects, including dizziness, giddiness, slight nausea, and headache”. Therefore, always look for brands that use a “cold pressed” extraction method instead.

7. What are the substitutes for Castor Oil?

If your skin is allergic to castor oil, you can try argan oil, jojoba oil, marula oil, grapeseed oil, avocado oil, rose oil, rosehip oil, apricot oil, or coconut oil for similar moisture boost.

If you have extremely oily skin, we recommend you to avoid using coconut oil because of its high comedogenic score. 

Final Note

Sky Organics brand is the no.1 brand with most number of positive reviews.

When shopping for the perfect castor oil product, stick to cold-pressed, pure, organic, and hexane free. It is because they are the safest options. Also, your castor oil should always come in an amber bottle, to protect it from UV rays.

You may come across Jamaican Black Castor Oil in your search, but this version tends to be heavier and less pure, with a higher pH level due to the ash from roasting the castor seeds.

If you have an eye-related condition, always consult your ophthalmologist before use, especially if you’re on other medication, or awaiting cataract surgery.
