Fuller, voluminous lashes are always the goal, but not everyone is blessed with thick eyelashes naturally. That’s where lash growth serums come into play. These helpful products can drastically change the thickness, fullness, and appearance of your eyelashes, giving you Instagram-worthy lashes without a single ounce of mascara.
How Do Lash Serums Work?
So, how do lash serums work exactly? Dr. Joshua Zeichner, the director of cosmetic and clinical research in the Department of Dermatology at Mount Sinai Hospital in New York City, says that a good lash serum performs two tasks. “They hydrate and coat the surface of the eyelashes to volumize the hair itself,” he tells InStyle. “[Or] they can either “directly stimulate the hair follicles or help create an optimal environment for hair follicle growth.”
Dermatologists recommend opting for natural lash growth serums, conditioners, and enhancers to prevent any potential signs of irritation in the eye area. Dr. Debra Jailman, a dermatologist based in New York City, suggests choosing formulas that feature hair-healthy ingredients like biotin, peptides, or lipids to ensure the best results. “Biotin is a B vitamin and helps lashes grow longer and thicker and stimulates the growth of additional eyelash follicles,” she explains. “Lipids condition and moisturize the lashes, and peptides specifically act on the skin cells of lashes to create a healthier foundation and boost volume.”
