The natural ingredient linked to 'reduced dark circles' and 'thicker lashes' - how to use for best results

The properties of the oil may make it particularly beneficial for individuals who suffer from dry or irritated skin, it's been claimed.

Some users have had success treating dark circles, hydrating skin and alleviating bloating, and growing thicker eyelashes and eyebrows.

Skin care expert Kimberley Medd shared some of the science behind castor oil’s effectiveness.

She said: “While there isn’t extensive research directly linking castor oil to reduced dark circles, its hydrating and nourishing qualities can potentially improve the appearance of the under-eye area.

“It’s worth trying if you’re looking for a natural remedy, but consistency is key.”

Castor oil's moisturising factors make it an excellent agent for hydrating the skin and hair.

“The fatty acids in castor oil help to hydrate and repair the skin’s barrier," explained Mett.

“This can be especially used for those with compromised skin conditions or anyone looking to enhance their skin’s moisture levels.”

Beyond skin care, the ingredient has gained traction for promoting longer and thicker eyelashes and brows.

“Many people use castor oil as a natural solution for fuller lashes and brows,” added the expert.

“Its rich nutrient profile supports hair health and while results can vary, it’s a popular choice for those seeking a natural beauty boost.”

When used as part of an oil pack, there is evidence castor oil can relieve abdominal bloating and discomfort, explained Medd.

“Castor oil packs are often used for their anti-inflammatory properties and can improve circulation and promote detoxification, which may reduce bloating and support overall digestive health.”

It comes as Liz, a 46-year-old American who launched the YouTube page Stylish and Graceful, recently spoke about the perks of using castor oil on her channel.
