SOL Co., Ltd. announced that its eyelash serum '0107 Eyelash Serum Premium,' designed for women over 40, has surpassed 20,000 units in cumulative sales just one year after its launch. The product addresses the common trade-off between effectiveness and low irritation by uniquely combining myristoyl pentapeptide-17 for eyelash vitality and rare human umbilical cord mesenchymal stem cell exosomes for gentle skin protection. Developed by two former eyelash salon owners over five years, the serum is now introduced in over 1,000 salons nationwide. Priced at 8,800 yen, it relies on word-of-mouth and will be exhibited at Beautyworld Japan Tokyo starting May 18, 2026.
