Castor oil moisturizes your eyelashes and can make them appear thicker and look like they have more luster. This serum is designed to enhance lash and eyebrow growth. 
 
The only way to achieve effective results with castor oil is to use it every night religiously. To give you an average estimate, it takes about 1-2 months for eyelashes to grow back and for you to notice a significant change in their thickness, length, and overall appearance.
