A 56-Day Exploratory Study of NatureU® Mind Care BeautyU Caps on Skin Aging Parameters

A 56-Day Single-Arm Exploratory Study of NatureU® Mind Care BeautyU Caps on Crow's-Feet Wrinkle Count, Skin Hydration, and Related Skin-Aging Parameters in Adult Women

This was a 56-day, single-center, open-label, single-arm exploratory study evaluating within-participant changes in skin-aging parameters after daily oral intake of NatureU® Mind Care BeautyU Caps in adult women. Participants took one capsule daily for 56 days. The primary outcome was change from baseline in crow's-feet wrinkle count at Day 56 assessed by PRIMOS CR imaging. The secondary outcome was change from baseline in stratum corneum hydration at Day 56 assessed by Corneometer CM 825. Additional exploratory outcomes included other wrinkle topography parameters, skin elasticity, radiance, pigmentation, pore-related parameters, dermal thickness and density, and participant-reported skin appearance outcomes.

The study was designed as an exploratory, signal-generating human evaluation of an oral nutricosmetic supplement. Adult female participants received NatureU® Mind Care BeautyU Caps once daily for 56 days and underwent skin assessments at baseline, Day 28, and Day 56. Instrumental assessments included PRIMOS CR imaging for wrinkle-related parameters and Corneometer CM 825 measurement for stratum corneum hydration. Additional skin-aging parameters were assessed using validated or commonly used skin analysis instruments according to the study protocol. The study was single-arm and open-label, with no placebo or parallel control group. Analyses were based on participants who completed the study assessments.
