Abstract

Introduction: An antiaging regimen that aids in clearing the matrix of waste products and stimulating neocollagenesis and neoelastogenesis was tested among a group of subjects over the course of 12 weeks to assess its efficacy in women with mild to moderate wrinkles and skin sagging on the face.

Materials and methods: The efficacy of the product regimen was tested in 22 subjects using investigator clinical grading measurements, raking light imaging, 3D imaging, biopsies, and self-assessment questionnaires at baseline and weeks 4, 8, and 12.

Results: Clinical grading indicated that use of the antiaging regimen for 12 weeks produced a statistically significant improvement in scores for all evaluated parameters; the raking light image analysis demonstrated a statistically significant improvement in values for length, width, and area of wrinkles when compared with baseline values as did 3D imaging. Biopsy results in the 5 patients tested showed improvement in solar elastosis, collagen stimulation, and improvement in cornified layers in all 5 patients. Elastin stimulation was evident in 3 of 5 patients. Results from the self-assessment questionnaire analysis indicated favorable responses in a statistically significant proportion of subjects after 12 weeks of use for all inquiries.

Conclusion: Use of this facial antiaging regimen was effective in improving visual facial photoaging conditions and well-perceived when used by women with mild to moderate wrinkles and skin sagging on the face under the conditions of this study.
