An interventional study of Placebo control and Experimental formula in Skin Condition, Eyelash Growth and Eyelashes, sponsored by Hungkuang University. Completed at 1 site in Taiwan. Open to female participants aged 18 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-06-12.

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 to receive either test product or placebo at 1:1 ratio. Participants will apply the product twice daily for 56 days (8 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 56), participant will be asked to fill out a questionnaire on the usage of the intervention and self evaluation of eyelash condition.
This prospective, randomized, double-blinded, placebo-controlled study aims to investigate the effects of Premium Rejuvenation Eyelash Serum on eyelashes and surrounding periorbital skin. A total of 30 healthy female adults aged 18 to 60 will be enrolled. Inclusion criteria require participants to be free from chronic diseases, major illnesses (including cancer, stroke-related disorders, paralysis, acute myocardial infarction, coronary artery bypass surgery, end-stage renal disease, or major organ/hematopoietic stem cell transplants), and allergic constitutions. Exclusion criteria include current use of medications or eyelash care products.
Participants will be randomly assigned into two groups of 15 each: Group 1 uses placebo (Base formula without active ingredient); Group 2 uses the experimental formula with ginger (Zingiber officinale)-derived extracellular vesicle + turmeric (Curcuma longa)-derived extracellular vesicles + IGF-1 + FGF-7. Baseline assessments will be conducted prior to product use. Follow-up assessments will occur at Days 28 (4 weeks) and 56 (8 weeks). Evaluations will include eyelash density, change in eyelash length, self-reported periorbital skin condition (e.g., swelling, irritation, pigmentation, redness, and allergic reactions), and a questionnaire. Eyelash parameters will be objectively measured using the Canfield Scientific VISIA® Skin Analysis System. At the conclusion of the study (Day 56), participant self-assessments on the intervention and eyelash condition will be evaluated through a questionnaire.

Other: Experimental formula

Eyelash density
Assess eyelash density with Canfield VISIA® Skin Analysis system by assigning score from 1 (most dense, thick eyelashes) to 5 (least dense, thin eyelashes). Results will be expressed as percentage of change in eyelash density percentage relative to Day 0.
Time frame: Assessment conducted every 28 days from Day 0 to Day 56 (including Day 0 as baseline)
Eyelash length
Assess eyelash length with Canfield VISIA® Skin Analysis system by assigning score from 1 (longest eyelashes) to 5 (shortest eyelashes). Results will be expressed as percentage of change in eyelash length percentage relative to Day 0
Time frame: Assessment conducted every 28 days from Day 0 to Day 56 (including Day 0 as baseline)
Participant self-assessment
Participants will be asked to fill out an assessment form with score from 0 to 5 for each of the eyelash condition and product feedback evaluated.
Time frame: Day 56 (End of the study period)
