What it is
Human stem cells are a component gaining attention in salons for their regenerative beauty benefits. They revitalize weakened cells. Therefore, focusing on eyelashes, we developed "human stem cells" with the same genetic structure as humans through biosynthesis. They directly target the roots, revitalizing weak, droopy eyelashes and those thinned with aging. They also activate melanin, resulting in beautiful, dark lashes. Four human peptides provide comprehensive support and care for the entire lash line. Can also be used on eyebrows! For those using eyelash extensions and perms! In addition to human stem cells, this product contains four other human-based ingredients for comprehensive hair support: KGF, aFGF, IGF-2, and Thymosin. Free of animal-derived ingredients, mineral oil, parabens, fragrances, pigments, and silicones. 100% nano-sized for smooth penetration into the hair roots. ------------------Regarding the use of eyelash serum products, the National Consumer Affairs Center of Japan issued a warning on August 8, 2019. To ensure safe and proper use, please read the instructions carefully before use. ------------------
