Understanding your natural lash cycle is key to maximizing results with any lash serum. Lashes grow in phases—anagen (growth), catagen (transition), and telogen (rest). Shigeru’s formula is designed to support the follicle during the anagen phase to speed up your eyelash growth and reduce fallout during the telogen phase. That's why consistent use of our eyelash serum with real results gives you thicker, longer lashes over time.
