Promotes Eyelash Growth: GrandeLASH-MD Eyelash Enhancing Serum contains a blend of vitamins, peptides, and amino acids that help promote natural eyelash growth, resulting in longer, thicker lashes in 4-6 weeks. It is ophthalmologist-tested and safe for use with contact lenses and eyelash extensions. Easy to Use: The serum is easy to use. After cleansing and drying your face, gently apply it to your eyelids, just above your upper lashes, like liquid eyeliner. It's recommended to use once a night before bed and allow the serum to dry for 1-2 minutes. The water-based formula is safe for use with contact lenses and eyelash extensions. Not only does it significantly improve the appearance of lashes, it also provides a gentle yet effective treatment for those seeking naturally enhanced lashes.
