This single-arm, cosmetic study will evaluate the efficacy of topical DMAE Oleate on facial skin firmness and lines/wrinkles in healthy adults. Thirty volunteers (40-55 years) will apply DMAE Oleate at night for 12 weeks (week 1: Monday/Wednesday/Friday/Sunday; weeks 2 to 12: nightly, one pump dose). Efficacy will be assessed at baseline, week 4, week 8, and week 12. The primary goals are to determine changes in fine lines/wrinkles at the crow's-feet region and biomechanical properties of the face skin. Wrinkle area, depth, and volume will be quantified by standardized VISIA-CR® image analysis, while firmness, elasticity, and fatigue will be measured with a Cutometer®. Participants will also complete a self-assessment questionnaire at each time point. Measurements are performed under identical conditions at all visits to enable within-subject comparisons from baseline.
