Clinical Study to Evaluate the Efficacy and Tolerability of Cosmeceuticals Targeting the Dermal-Epidermal Junction.

OBJECTIVE
The dermal-epidermal junction (DEJ), composed of rare proteins, plays a significant role in facial skin aging. A newly enhanced multi-ingredient anti-aging facial moisturizer (MFM) and eye cream (MEC) were formulated to target DEJ-related aging. The objective of this study is to assess the efficacy and tolerability of a dual-product regimen MFM and MEC as a treatment in improving intrinsically and extrinsically aged facial and periorbital skin.


METHOD
Forty-two female subjects, 42 to 65 years, Fitzpatrick skin type I–VI, with mild to moderate droopy eyelids, moderate crow’s feet wrinkles, and moderate global photodamage completed this institutional review board (IRB)-approved study. Subjects applied the MFM and MEC twice-daily for 12 weeks. Clinical grading of efficacy and tolerability parameters, VISIA®-CR imaging, image analysis of wrinkles, skin pH, Tewameter, and pinch recoil measurements were performed at baseline, weeks 4, 8, and 12. Optical coherence tomography (OCT) imaging was performed at baseline and week 12.


RESULTS
Statistically significant improvement was shown in both clinically graded parameters and bio-instrumentational analyses at all time points. Both products were well tolerated by subjects.


CONCLUSION
This IRB-approved clinical study demonstrated effectiveness in improving intrinsic and extrinsic signs of the global face and periorbital eye area aging after twelve weeks of twice-daily application. J Drugs Dermatol. 2021;20(12):1314-1321. doi:10.36849/JDD.6355.
