What is the primary purpose of eyelash serums?

The primary purpose of eyelash serums is to promote lash growth and health. These products are formulated with specific ingredients designed to nourish the hair follicles, which can lead to longer, thicker, and healthier eyelashes over time. By providing essential nutrients and conditioning agents, eyelash serums can enhance the overall condition of the lashes, potentially reducing brittleness and breakage, resulting in a fuller appearance.

While some factors like darkening or creating volume and curl are desirable aspects of eyelash aesthetics, they aren't the main function of eyelash serums. Darkening is typically achieved through other products, such as mascaras or dyes, and volume or curl is often created with styling tools or techniques. Additionally, while easier application of lash extensions can be an ancillary benefit of healthier lashes, it is not the fundamental goal of using eyelash serums. Therefore, the emphasis remains on promoting lash growth and their overall health as the core purpose.
