Is it Safe to Put Castor Oil on Eyelashes in 2024?

Is it Safe to Put Castor Oil on Eyelashes in 2024? Castor oil has become a popular natural remedy for growing thicker, longer eyelashes. But is it truly safe to put this oil so close to your eyes? Let’s take a closer look at the benefits and potential risks of using castor oil on eyelashes.

What is castor oil?

Castor oil is a vegetable oil extracted from the seeds of the castor oil plant (Ricinus communis). It has been used medicinally for centuries thanks to its anti-inflammatory and antimicrobial properties. Castor oil also contains ricinoleic acid, a fatty acid that penetrates skin and helps stimulate blood circulation.


When applied topically, castor oil is thought to boost circulation and nutrient delivery to hair follicles. This can promote growth of thicker, longer hairs like eyelashes.

Benefits of castor oil for lashes

There are several reasons why castor oil is touted for eyelash growth:

Promotes growth

The ricinoleic acid in castor oil can help nourish eyelash follicles, encouraging new growth. Applying castor oil regularly may help eyelashes grow thicker and stronger over time.

Conditions lashes

Castor oil is also very moisturizing. Coating lashes in this oil can prevent dryness, brittleness, and breakage. Well-conditioned lashes are less prone to falling out prematurely.

Prevents breakage

In addition to conditioning lashes, castor oil forms a protective layer that shields them from damage. This may prevent breakage and loss of lashes as they grow out.

Is it Safe to Put Castor Oil on Eyelashes

When used properly, castor oil is generally considered safe for eyelashes. However, there are a few precautions to keep in mind:

Pure, cold-pressed castor oil is gentle

Look for cold-pressed, hexane-free castor oil. This type retains more of the oil’s natural compounds and is less likely to cause irritation.

Patch test recommended

Apply a tiny bit of castor oil to your arm first. If no reaction occurs after 24 hours, it should be safe to use on eyelids and lashes.

Avoid getting in eyes

Take care not to let castor oil drip into your eyes as this can cause stinging and irritation. Use an eyeliner brush or clean mascara wand to apply.
