Castor oil, derived from the beans of the castor tree, is rich in fatty acids that nourish the skin and promote hair growth. It has been widely used for longer, thicker eyelashes, thanks to its natural moisturizing properties.
Aside from beauty benefits, castor oil is also known as a natural laxative, an anti-aging ingredient, and an acne treatment. It is a common ingredient in beauty products because it hydrates without clogging pores or irritating the skin.
If you’re looking for a natural, budget-friendly way to enhance your eyelashes, try these DIY castor oil serums using different nourishing ingredients.
