Eyelash Effect Evaluation for Premium Rejuvenation Eyelash Serum

This study aims to evaluate the efficacy of the Premium Rejuvenation Eyelash Serum on eyelashes and the surrounding periorbital skin. A total of 30 healthy female participants, aged 18 to 60, will be recruited and randomly assigned to two groups receiving different serum formulations. Participants will apply the product twice daily for 112 days (16 weeks), with eyelash and periorbital skin conditions assessed at multiple time points using non-invasive measurements. Key parameters include eyelash density, eyelash length, and overall periorbital skin condition. At the end of the study (Day 112), both participant self-assessments and evaluations by an eyelash specialist will be conducted to assess changes in eyelash and skin condition.
