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.
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), 56 (8 weeks), 84 (12 weeks), and 112 (16 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 112), both participant self-assessments and evaluations by an eyelash specialist will be conducted to assess eyelash and surrounding skin condition.

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.

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 112 (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 112 (including Day 0 as baseline)
Periorbital skin and eye conditional questionnaire
Participants will be asked to answer a questionnaire for self-assessment of periorbital skin conditions such as swelling, irritation, pigmentation, redness, and allergic reaction; corneal and retinal conditions including swelling, hyperemia, and allergic reaction will also be self-evaluated.
Time frame: Assessment conducted every 28 days from Day 0 to Day 112 (including Day 0 as baseline)
Participant self-assessment
Participants will be asked to fill out an assessment form with score from 0 to 4 for each of the eyelash condition and product feedback evaluated.
Time frame: Day 112 (End of the study period)
Eyelash specialist assessment
An eyelash specialist will assess and eyelash and periorbital skin condition of the participant and assign a score from 0 to 4 for each of the evaluated items as well as assign a score of Global Aesthetic Improvement Scale (GAIS) from -1 to 3.
Time frame: Day 112 (End of the study)
