Eyelash Effect Evaluation for Premium Rejuvenation Eyelash Serum

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.

• Placebo control (Other): Placebo Control (Base Formula without active ingredients). After thoroughly cleansing the face and removing contact lenses (if applicable), apply 1 mL of the serum evenly to the base of the eyelashes. Allow the serum to absorb for a few minutes. Repeat application twice daily, in the morning and evening.
• Experimental formula (Other): Base formula with ginger (Zingiber officinale)-derived extracellular vesicle, turmeric (Curcuma longa)-derived extracellular vesicles, insulin growth factor-1 (IGF-1), and fibroblast growth factor-7 (FGF-7). After thoroughly cleansing the face and removing contact lenses (if applicable), apply 1 mL of the serum evenly to the base of the eyelashes. Allow the serum to absorb for a few minutes. Repeat this application twice daily, in the morning and evening.

Primary outcomes

• Eyelash density [Assessment conducted every 28 days from Day 0 to Day 56 (including Day 0 as baseline)]: 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.
• Eyelash length [Assessment conducted every 28 days from Day 0 to Day 56 (including Day 0 as baseline)]: 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

Secondary outcomes

• Participant self-assessment [Day 56 (End of the study period)]: 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.
