Here's a bright idea: Try a biotin supplement to encourage thicker, fuller lashes from the inside out. GRO Biotin Gummies are a thing of beauty: heart-shaped, gelatin-free, all-vegan and brimming with vitamins of the B family, as well as vitamin A, vitamin C and vitamin E, along with zinc. Or try the relaxing, full-spectrum CBD gummy. Pair these habits with an eyelash enhancing serum and you'll be on your way to supporting follicle health.
