Unlock The Secret To Gorgeous Lashes: Castor Oil For Eyelashes.

Castor oil for eyelashes

Castor oil. The stickiest oil I have ever used has several benefits. One of them is using castor oil for eyelashes. The oil is a vegetable oil that is sourced from the castor tree. The castor tree is mainly grown in the southeastern Mediterranean basin, eastern Africa, and India. 

Scientifically named Ricinus communis, this plant is usually sourced for the oil and is known to have moisturizing properties compared to other known vegetable oils. The seeds from the castor bean help in the extraction of the oil, and both local and international clients use it. 

The primary use of this oil has been as a hair oil. I use it as a carrier oil for essential oils such as peppermint or rosemary

The oil from the Castor plant is an excellent addition for various issues. It has seen diverse uses throughout history, from skin ailments to others. The rich amount of ricinoleic acid in the seed allows the oil to act as a moisturizing agent. It has excellent nourishing capabilities. 

The high levels of essential fatty acids in the oil (such as the one mentioned above) are a great detoxifying agent. The interaction between the oil and the skin or hair is essential to understand its benefits. 

The thick oil prevents the evaporation of water from the skin’s surface as it acts as an emollient. The thickness of the oil makes it “heavy,” which is why most people do not opt for this oil readily. 

The oil is known to have natural humectants- the fatty acids that are present in the oil are helpful to prevent the loss of water. This promotes good skin health, relieves dryness, and supports the skin structure. The oil is also known to soothe inflammation.

The evidence remains divided on this question. Some researchers and beauty gurus on instagram or YouTube will recommend it as a growth booster. However, most scientific evidence points towards the poor support for renewed growth. 

The oil aids in decreasing the risk of breakage and hydrates the lashes. However, the lashes do not grow faster or denser than the natural type. 

You may consider getting an eyelash extension if you want a fuller look. They are a reasonably cheap technique that lets you reach your desired eyelash look, which is long-lasting. 

Is Castor Oil Safe For Eyelashes?

The safety of the castor oil depends on your skin’s allergy to the substance. Usually, the allergies develop towards things not close to the body’s composition. This causes an issue for the body to adapt to the ingredients. The immune system (our bodyguards) recognizes those substances as allergens (attackers). 

The safety of eyelashes has been vouched for by several other users worldwide who share their experiences through online forums or their channels. I am one of those who has experienced benefits after using this oil. 

I can also vouch for the safety of this oil for eyelashes- I use this oil thrice a week as I’m not too fond of the thickness. However, I have found a hack to use it, which I will shortly share with you. 

Castor oil is a natural product compared to the various eyelash growth products available in the market. Thus, there are fewer chances of side effects. The main motive is to use it in moderate amounts so that there are no side effects. 

The regular use of the oil may lead to irritation. However, using it during breaks has improved my eyelash health. Especially for people who use eye makeup such as mascara, castor oil as the “eye serum” is a seemingly good choice.
