Abstract:

BACKGROUND: Skin aging is a multifactorial process induced by intrinsic factors such as metabolic processes and senescence as well as environmental factors, including smoking, air pollution, and solar radiation. UV-induced production of reactive oxygen species induces skin photoaging. Antioxidants, including vitamin C and E and green tea polyphenols represent a promising strategy for the aesthetic improvement of clinical features associated with aging.

OBJECTIVE: To assess the safety, tolerability, and efficacy of a novel vitamin C and E and green tea polyphenols (CE-GTP) combination serum on photoaged facial skin.

METHODS: 31 healthy females aged 43 to 65 years (mean age, 57.9) participated in this single-center, 12-week clinical trial. Subjects applied CE-GTP serum twice daily for the duration of the study. Clinical grading of efficacy parameters, safety and tolerability evaluations, ultrasound measurements, and self-assessment questionnaires were conducted at several study milestones.

RESULTS: Statistically significant improvements were observed in all clinically graded efficacy parameters. Highlights include reduction in fine lines around the eye area and facial wrinkles and enhanced skin smoothness and radiance. Ultrasound measurements showed a statistically significant increase in skin density at week 12 compared with baseline, indicating thickening of the epidermal and dermal tissue, associated with youthful, healthier skin. Subjects self-reported numerous improvements, including reduction of fine lines and wrinkles, improved skin tone and texture, diminished look of dark spots, and improved skin elasticity.

CONCLUSION: Novel CE-GTP serum is safe and effective, as shown by statistically significant improvements in multiple aesthetically important objective, subjective, and patient reported outcomes. J Drugs Dermatol. 2021;20(9):996-1003. doi:10.36849/JDD.5818.
